A. statistically significant difference in the mean blood hemoglobin levels between breastfed infants and formula-fed infants at α = 0.05.

B. the 95% confidence interval for the difference in population means between breast-fed infants and formula-fed infants is (−0.06, 1.18).

C. Both the hypothesis test and the confidence interval lead to the same conclusion that there is a difference in the mean blood hemoglobin levels between the two feeding regimens.

What is null hypothesis?

In statistics, the null hypothesis (H0) is a statement that assumes that there is no significant difference between two or more groups, samples, or populations.

(a) To test the hypothesis that there is a difference in the population means between breast-fed infants and formula-fed infants, we can use a two-sample t-test with equal variances. The null hypothesis is that the population means are equal, and the alternative hypothesis is that they are not equal. Using α = 0.05 as the significance level, the critical value for a two-tailed test with 40 degrees of freedom is ±2.021.

The test statistic can be calculated as:

t = (x1 - x2) / (Sp * √(1/n1 + 1/n2))

where x1 and x2 are the sample means, Sp is the pooled standard deviation, and n1 and n2 are the sample sizes. The pooled standard deviation can be calculated as:

Sp = √(((n1 - 1) * s1² + (n2 - 1) * s2²) / (n1 + n2 - 2))

where s1 and s2 are the sample standard deviations.

Plugging in the values from the table, we get:

t = (13.3 - 12.4) / (1.776 * √(1/23 + 1/19)) = 2.21

Since the absolute value of the test statistic is greater than the critical value, we reject the null hypothesis and conclude that there is a statistically significant difference in the mean blood hemoglobin levels between breastfed infants and formula-fed infants at α = 0.05.

(b) To construct a 95% confidence interval for the difference in population means between breast-fed infants and formula-fed infants, we can use the formula:

(x1 - x2) ± tα/2,Sp * √(1/n1 + 1/n2)

where tα/2,Sp is the critical value of the t-distribution with (n1 + n2 - 2) degrees of freedom and α/2 as the significance level.

Plugging in the values from the table, we get:

(x1 - x2) ± tα/2,Sp * √(1/n1 + 1/n2)

= (13.3 - 12.4) ± 2.021 * 1.776 * √(1/23 + 1/19)

= 0.56 ± 0.62

Therefore, the 95% confidence interval for the difference in population means between breast-fed infants and formula-fed infants is (−0.06, 1.18).

(c) The hypothesis test and the confidence interval both lead to the conclusion that there is a difference in the mean blood hemoglobin levels between breast-fed infants and formula-fed infants. In part (a), we rejected the null hypothesis that the population means are equal, which means we concluded that there is a difference. In part (b), the confidence interval does not contain 0, which means we can reject the null hypothesis that the difference in means is 0 at the 95% confidence level.

Therefore, both the hypothesis test and the confidence interval lead to the same conclusion that there is a difference in the mean blood hemoglobin levels between the two feeding regimens.

The number of 5-digit numbers in which every two neighboring digits differ by 3 is 144.

To find the number of 5-digit numbers in which every two neighboring digits differ by 3, we can start by considering the possible values for the first digit.

The first digit can be any number from 1 to 9 (since it's a 5-digit number). Let's analyze the possibilities:

If the first digit is 1, the second digit can be either 4 or 8.

If the first digit is 2, the second digit can be either 5 or 9.

If the first digit is 3, the second digit can be either 6 or 0.

If the first digit is 4, the second digit can be either 7 or 1.

If the first digit is 5, the second digit can be either 8 or 2.

If the first digit is 6, the second digit can be either 9 or 3.

If the first digit is 7, the second digit can be either 0 or 4.

If the first digit is 8, the second digit can be either 1 or 5.

If the first digit is 9, the second digit can be either 2 or 6.

After determining the possibilities for the first two digits, we can continue this pattern for the next three digits. Each digit will have two possible options, determined by the previous digit.

Hence, the total number of possibilities is obtained by multiplying the number of choices for each digit

Number of possibilities = 9 (options for the first digit) × 2 (options for the second digit) × 2 (options for the third digit) × 2 (options for the fourth digit) × 2 (options for the fifth digit)

= 9 × 2⁴

= 9 × 16

= 144

Therefore, the number of 5-digit numbers in which every two neighboring digits differ by 3 is 144.

Answer:

What forces act on the ball in the horizontal direction as it rolls? None. So that means there is no horizontal acceleration and therefore the horizontal component of the ball's speed is constant.

And since the ball was only travelling horizontally at the instant it rolled off the table, initially the vertical component of its speed is 0. That means the time taken to hit the ground after rolling off the table is the same as if it was just dropped 0.950 m. We can find this time using one of the kinematic equations of motion in the vertical direction, taking downwards as positive. Then we have the following information:

u = initial velocity = 0 m/s

d = distance fallen = 0.950 m

a = acceleration (due to gravity) = 9.8 m/s²

t = time = ?

d = ut + 1/2 at². Since u = 0 this reduces to d = 1/2 at² and rearranges to t = √(2d/a) = √(2*0.95/9.8) = 0.4403 s.

In the same amount of time, the ball travels a horizontal distance of 0.352 m. We already know the horizontal velcoity is constant, so horizontal velocity is just horizontal distance divided by time = (0.352 m)/(0.4403 s) = 0.799 m/s.

The slope of the line that divides the region bounded by the parabola \(y=5x-3x^2\)and the x-axis into two regions with equal area is 5.

To find the slope of the line that divides the region into two equal areas, we need to determine the point of intersection between the parabola and the x-axis. Since the line passes through the origin, its equation will be y = mx, where m represents the slope.

Setting the equation of the parabola equal to zero, we find the x-values where the parabola intersects the x-axis. By solving the equation\(5x - 3x^2 = 0\), we get x = 0 and x = 5/3.

To divide the region into two equal areas, the line must pass through the midpoint between these x-values, which is x = 5/6. Plugging this value into the equation of the line, we have y = (5/6)m.

Since the areas on both sides of the line need to be equal, we can set up an equation using definite integrals. By integrating the equation of the parabola from 0 to 5/6 and setting it equal to the integral of the line from 0 to 5/6, we can solve for m. After performing the integration, we find that m = 5.

Therefore, the slope of the line that divides the region into two equal areas is 5.

The numbers of flowers spaced every 4 feet, are needed

to surround a circular garden with a 70-foot radius, 105

Circumference is the distance around the perimeter of a circular object. It is defined as the length of the circle that is found by multiplying the diameter of the circle by π (pi), which is approximately equal to 3.14.

The formula for the circumference of a circle is given by:

C = 2πr,

To calculate the circumference of the circular garden, we can use the formula:

C = 2πr

where C is the circumference, π is the mathematical constant pi (approximated as 3 in this case), and r is the radius. Plugging in the given values, we have:

C = 2 x 3 x 70

  = 420 feet

Now, since the flowers are spaced every 4 feet, we can divide the circumference by 4 to find the number of flowers needed:

number of flowers = C / 4

                               = 420 / 4

                               = 105

Therefore, 105 flowers spaced every 4 feet are needed to surround a circular garden with a 70-foot radius.

2x + 9 + 3x + x = 6x

2x + 9 + 3x + x = 15

2x + 9 + 3x + x = 6x + 9

Based on the given conditions,

(1) No solutions :

There will be no solutions when the left side is inconsistent with the right side:

2x + 9 + 3x + x =  _ x + _

We can sum of difference,

6x + 9 = 6x

Subtract 6x from both sides,

6x - 6x = -9

9 = 0

9 = 0 which is absurd and hence the equation has no solution.

(2) One solutions :

There will be one solution when the left side and right side are not inconsistent and not the same.

2x + 9 + 3x + x = 15

6x + 9 = 15

Subtract 9 from both sides.

6x = 6

Divide both sides by 6.

x = 1 and this is the only solution.

(3) Infinity solutions :

There will be an infinite number of solutions when the equation is true for any value of x. This will be the case when the left side and right side are identical.

2x + 9 + 3x + x = 6x + 9

6x + 9 = 6x + 9

Subtract 6x from both sides,

9 = 9, both sides are balanced which means, the equation has infinitely many solutions.

Therefore,

2x + 9 + 3x + x = 6x

2x + 9 + 3x + x = 15

m3 = 79 degrees and m3 is also 35 in this parallelogram. In a parallelogram, opposite angles are equal. Given that m2 = 3x - 28 and m4 = 2x - 7, we know that m3 is equal to m1.

Since m1 and m2 are consecutive angles, their sum equals 180 degrees. So, we have:
m1 + m2 = 180
m1 + (3x - 28) = 180
Now, we also know that m1 is equal to m4:
m1 = 2x - 7
Substitute m1 back into the first equation:
(2x - 7) + (3x - 28) = 180
Combine like terms:
5x - 35 = 180
Add 35 to both sides:
5x = 215
Divide by 5:
x = 43
Now, find m3 which is equal to m1:
m3 = m1 = 2x - 7
m3 = 2(43) - 7
m3 = 86 - 7
m3 = 79
So, m3 = 79 degrees.

To find m3 in a parallelogram, we know that opposite angles are congruent. So, m2 is congruent to m4, and m1 is congruent to m3. Therefore, we can set m2 equal to m4 and solve for x:
m2 = m4
3x - 28 = 2x - 7
x = 21
Now that we know x, we can substitute it into either m2 or m4 to find their values, which are both equal:
m2 = 3x - 28
m2 = 3(21) - 28
m2 = 35
So, we know that m2 and m4 are both 35. Since opposite angles are congruent in a parallelogram, we know that m1 is also 35. And since m1 is congruent to m3, we have:
m3 = m1
m3 = 35
Therefore, m3 is also 35 in this parallelogram.

Now... 3/6 + 5/6 = 8/6

8/6 will have to be converted into a mixed number so...

that will be 1 2/6

8 + 2/6 = 8 2/6

now simplify that and you get 8 1/3
