The sum of two consecutive natural numbers is 575. Find the numbers. (Enter your answers as a comma-separated list.)

Answers

Answer:

Step-by-step explanation:

To find the two consecutive natural numbers whose sum is 575, we can set up the following equation:

x + (x+1) = 575

where x and x+1 are the two consecutive natural numbers.

We can solve this equation by combining like terms:

2x + 1 = 575

Subtracting 1 from both sides, we get:

2x = 574

Dividing both sides by 2, we get:

x = 287

Therefore, the two consecutive natural numbers are 287 and 288. Our final answer is 287, 288.

Answer:

287,288

Step-by-step explanation:

Question

The sum of two consecutive natural numbers is 575. Find the numbers

soln

x +( x + 1) = 575

x + x + 1 = 575

2x + 1 = 575

2x = 575 – 1

2x = 574

$ \frac{2x}{2} = \frac{574}{2} $

x = 287

since we got x as 287, lets solve(x+1)

by substituting

287 + 1 = 288

hence the consecutive numbers are 287,288

Check

287 + 288 = 575

we are correct.

The human heart beats approximately 1.152x10^5 times per day. Approximately how many times does the heart beat per year?

Answers

The number of times does the heart beats per year is 4.2 x 10^7 times

How to determine the number of times does the heart beat per year?

From the question, the given parameters are:

The human heart beats approximately 1.152x10^5 times per day

This means that

Daily heart beat = 1.152 x 10^5 times per day

There are 365 days in a year

So, the number of heart beats in a year is the product of the number of days in a year by the daily heart beats

So, we have

Yearly heart beat = Number of days in a year * Daily heart beat

Substitute the known values in the above equation

Yearly heart beat = 365 * 1.152 x 10^5 times

Evaluate the products

So, we have

Yearly heart beat = 420.48 x 10^5 times

Rewrite as

So, we have

Yearly heart beat = 4.2048 x 10^7 times

Approximate

Yearly heart beat = 4.2 x 10^7 times

Hence, the number of times does the heart beats per year is 4.2 x 10^7 times

Q: A baseball is hit into the air by the Blue Jays' batting coach.
It's height h, in meters, after t seconds is h = - 4.9t² + 27.44t + 0.584

(a) write the equation in vertex form by completing the square

b) How high off the ground was the ball when it was hit?

c) When does the ball reach it's maximum height? what is it's maximum height?

d) For how long is the ball in the air ? Round answer to 1 decimal place

Answers

The ball is in the air for approximately 2.8 + √7 seconds, which rounds to 5.2 seconds when rounded to one decimal place.To write the equation in vertex form, we need to complete the square.

The given equation is h = -4.9t² + 27.44t + 0.584. We can rewrite it as:

h = -4.9(t² - 5.6t) + 0.584

Now, we want to complete the square inside the parentheses. To do this, we need to add and subtract the square of half the coefficient of t. In this case, the coefficient is -5.6, so we have:

h = -4.9(t² - 5.6t + (5.6/2)² - (5.6/2)²) + 0.584

Simplifying, we get:

h = -4.9((t - 2.8)² - 2.8²) + 0.584

Expanding further:

h = -4.9(t - 2.8)² + 4.9(2.8)² + 0.584

Thus, the equation in vertex form is: h = -4.9(t - 2.8)² + 34.328

b) The ball's height when it was hit can be found by evaluating the equation at t = 0:

h = -4.9(0 - 2.8)² + 34.328

h = -4.9(-2.8)² + 4.328

h = -4.9(7.84) + 34.328

h ≈ 0.784 meters

To find the time at which the ball reaches its maximum height, we can use the fact that the maximum height occurs at the vertex of the parabolic equation. The vertex of a parabola in the form h = a(t - h₀)² + k is given by (h₀, k). Comparing this to our equation, we can see that the vertex occurs at t = 2.8 and h = 34.328. Therefore, the ball reaches its maximum height at 2.8 seconds, and the maximum height is 34.328 meters.

The total time the ball is in the air can be determined by finding the time it takes for the ball to reach the ground. When the ball hits the ground, its height is 0. To find this time, we can set the equation equal to 0 and solve for t:

0 = -4.9(t - 2.8)² + 34.328

4.9(t - 2.8)² = 34.328

(t - 2.8)² ≈ 7

t - 2.8 ≈ ±√7

t ≈ 2.8 ± √7

Since time cannot be negative in this context, we can ignore the negative value.

PEMDAS is the order of operations, and stands for:

First, add 5 to both sides of the equation:

7y - 5 = 51

7y - 5 (+5) = 51 (+5)

7y = 51 + 5

7y = 56

Next, divide 7 from both sides of the equation:

(7y)/7 = (56)/7

y = 56/7

y = 8

8 is your answer for y.

solve the system by substitution × = 6y -22x +5y =47

Answers

We have the following system:

$\begin{gathered} x=6y-2\ldots(A) \\ 2x+5y=47\ldots(B) \end{gathered}$

Solving by substitution method.

If we substitute equation A into B, we get

$2(6y-2)+5y=47$

which gives

$12y-4+5y=47$

By combining similar terms, we have

$\begin{gathered} 12y+5y-4=47 \\ 17y-4=47 \end{gathered}$

If we move -4 to the right hand side, we obtain

$\begin{gathered} 17y=47+4 \\ 17y=51 \end{gathered}$

Then, if we move the coefficient of y to the right hand side, wehave

$\begin{gathered} y=\frac{51}{17} \\ y=3 \end{gathered}$

Then, we can substitute this result into equation A, which gives

$x=6(3)-2$

so, xi given by

Therefore, the answer is

Answer:

Hi! The answer would be 21.

Step-by-step explanation:

Based on the table, what is the equation of the linear relationship in slope-intercept form?
y = 2x − 8
y = 2x + 8
y = −2x + 4
y = −2x − 4

Answers

The equation of the linear relationship in slope-intercept form is y = 2x - 8. Option A is the correct answer.

To determine the equation of the linear relationship in slope-intercept form based on the table, we need to find the slope and y-intercept.

By observing the table, we can calculate the slope by selecting any two points. Let's choose the points (0, -8) and (4, 0).

Slope (m) = (change in y) / (change in x)

= (0 - (-8)) / (4 - 0)

= 8 / 4

= 2

Now that we have the slope, we can find the y-intercept by substituting the values of one point and the slope into the equation y = mx + b and solving for b.

Using the point (0, -8):

-8 = 2(0) + b

b = -8

Therefore, the equation of the linear relationship in slope-intercept form is: y = 2x - 8. Option A is the correct answer.

(make sure to type a zero in front of the decimal place ie. 0.1 vs .1 otherwise your answer will be marked incorrect) Lower limit

Answers

Answer:

99% Confidence interval is given as;

Lower Limit = 0.062

Upper Limit = 0.130

Step-by-step explanation:

Given the data in the question;

x = 48

n = 500

sample proportion p = x/n = 48/500 = 0.096

with 99% confidence

significance level ∝ = 1 - 99% = 1 - 0.99 = 0.01

∝/2 = 0.01 / 2 = 0.005

Critical Z-value = $Z_{\alpha /2$ = $Z_{0.005$ = 2.576

Now,

Standard error of p : SE = √[ (p × ( 1 - p) / n ) ]

we substitute

SE = √[ (0.096 × ( 1 - 0.096) / 500 ) ]

SE = √[ (0.096 × 0.904) / 500 ]

SE = √[ 0.086784 / 500 ) ]

SE = 0.0131745

Margin of Error E = $Z_{\alpha /2$ × SE

E = 2.576 × 0.0131745

E = 0.0339

Now 99% confidence interval will be

⇒ 0.096 ± 0.0339

⇒ (0.096 - 0.0339, 0.096 + 0.0339 )

⇒ ( 0.062, 0.130 )

Lower Limit = 0.062

Upper Limit = 0.130

A random sample of adult men was asked if they would return the money if they found a wallet on the street. Of 143 men, 29 said they would. The true proportion of all adult men who would return the money is 18%. Which of the following do you expect would accurately describe the sampling distribution of the sample proportion of men would return money from a found wallet?
Select one or more:
a. The mean of the sampling distribution will be equal to 0.18.
b. The mean of the sampling distribution will be equal to 0.2028.
c. The sampling distribution would be approximately standard normal.
d. The sampling distribution will be skewed right.
e. The sampling distribution will be skewed left.
f. The sampling distribution will be approximately normal.
g. The standard deviation of the sampling distribution will be 0.0336.

Answers

Answer:

b. The mean of the sampling distribution will be equal to 0.2028.

f. The sampling distribution will be approximately normal.

g. The standard deviation of the sampling distribution will be 0.0336.

Step-by-step explanation:

We use the Central Limit Theorem to solve this question.

Central Limit Theorem:

For a proportion p in a sample of size n, the sampling distribution of the sample proportion will be approximately normal with mean $\mu = p$ and standard deviation $s = \sqrt{\frac{p(1-p)}{n}}$.

The sample proportion being approximately normal means that option f. is correct.

Of 143 men, 29 said they would.

This means that $p = \frac{29}{143} = 0.2028$

This means that option b is correct.

g. The standard deviation of the sampling distribution will be 0.0336.

Lets find the standard deviation.

Sample of 143, so $n = 143$

$s = \sqrt{\frac{0.2028*0.7972}{143}} = 0.0336$

So option g. is correct.

The statements that accurately describe the sampling distribution of the sample proportion of men would return money from a found wallet are;

B) The mean of the sampling distribution will be equal to 0.2028.

F) The sampling distribution will be approximately normal.

G) The standard deviation of the sampling distribution will be 0.0336.

Central Limit Theorem.

We are given the true proportion of all adult men who will return the money as; p = 18% = 0.18

Thus, the population mean = 0.18

Now, out of 143 men, 29 said they will return the money. Thus;

Sample mean = Sample proportion = 29/143 = 0.2028

The formula for the sampling standard deviation is;

s = √[p^(1 - p^)/n]

s = √[0.2028(1 - 0.2028)/143]

s = √0.001130574545

s = 0.0336

Looking at the options and comparing to the answers gotten above, only option B, F and G are correct.
