Answer:

7/9

Step-by-step explanation:

-7/5÷-9/5

- cancelled with each other

(7×5)/(9×5)

5 also cancelled with 5

then your answer is 7/9

Answer: 900

Step-by-step explanation:

To estimate the value of √81.3 × 98.8, we can first simplify the expression inside the square root:

√81.3 ≈ √81 = 9

Then, we can estimate the product of 9 and 98.8 by rounding 98.8 to 100 and multiplying:

9 × 100 = 900

Therefore, an estimate for the value of √81.3 × 98.8 is approximately 900.

________________________________________________________

We can estimate the value of \(\sqrt{81.3}\) as approximately \(9\) and the value of \(98.8\) as approximately \(100\). Then we have:

\({\sqrt{81.3} \times 98.8 \approx 9 \times 100 = \boxed{900}}\)

This is a rough estimate of the actual value, but it should be close enough for most purposes.

The length of side X in simple radical form with a rational denominator is 25/√3.

In Mathematics and Geometry, a 30-60-90 triangle is also referred to as a special right-angled triangle and it can be defined as a type of right-angled triangle whose angles are in the ratio 1:2:3 and the side lengths are in the ratio 1:√3:2.

This ultimately implies that, the length of the hypotenuse of a 30-60-90 triangle is double (twice) the length of the shorter leg (adjacent side), and the length of the longer leg (opposite side) of a 30-60-90 triangle is √3 times the length of the shorter leg (adjacent side):

Adjacent side = 5/√3

Hypotenuse, x = 5 × 5/√3

Hypotenuse, x = 25/√3.

The value of p when q is 2 is 1

Inverse variation is the relationships between variables that are represented in the form of y = k/x, where x and y are two variables and k is the constant value.

This means that has x increases y will decrease and vice versa.

If p is inversely proportional to q , then p = kq

when p = 2, q = 4

2 = k4

k = 2/4

k = 1/2

When q = 2

p = 1/2 × 2

p = 1

We can say that the tree's height increased by 12.5% over the course of the six-week experiment.

To calculate the percent increase in the tree's height, we need to find the difference between its new height and its old height, and then express that difference as a percentage of the old height.

We start with the formula:

percent increase = (new value - old value) / old value * 100%

In this case, the old value is the height of the tree at the beginning of the experiment, which is 32 inches. The new value is the height of the tree six weeks later, which is 36 inches.

So, plugging in those values, we get:

percent increase = (36 - 32) / 32 * 100%

Simplifying this expression gives us:

percent increase = 4 / 32 * 100%

And when we evaluate that expression, we get:

percent increase = 12.5%

Therefore, the percent increase in the tree's height is 12.5%.

Step-by-step explanation:

we are looking for the greatest common factor of the 3 numbers.

e.g. by prime factorization :

18 = 2×3×3

36 = 2×2×3×3

45 = 3×3×5

the largest chain of prime factor multiplication that is contained in all 3 numbers is 3×3.

the GCF is therefore 3×3 = 9.

Answer:

the ratio is 6:11

Step-by-step explanation:

Yes, they are quite similar. the p-value obtained using the theory-based method (p < 0.0001) agree with that obtained using the randomization/simulation - based method (p < 0.0001)

P- value is the probability of obtaining a value of test statistic more extreme in the direction of alternative hypothesis than the observed one. In easy words if p -value < level of significance we reject H0 in favor of H1.

Here:

p-value < 0.0001 => we reject H0.

If the statistical software renders a p value of 0.000 it means that the value is very low, with many "0" before any other digit.

So the interpretation would be that the results are significant, same as in the case of other values below the selected threshold for significance.

Therefore, yes they are quite similar.

Step-by-step explanation:

Let x and (x + 1) be the page numbers Josiah can see

Hint 1: x(x + 1) = 930

⇒ x² + x = 930

⇒ x² + x - 930 = 0

Using quadratic formula,

\(x = \frac{-b\pm\sqrt{b^2 -4ac} }{2a}\)

a = 1, b = 1 and c = -930

\(x = \frac{-1\pm\sqrt{1^2 -4(1)(-930)} }{2(1)}\\\\= \frac{-1\pm\sqrt{1 +3720} }{2}\\\\= \frac{-1\pm\sqrt{3721} }{2}\\\\= \frac{-1\pm61 }{2}\\\)

\(x = \frac{-1-61 }{2}\;\;\;\;or\;\;\;\;x= \frac{-1+61 }{2}\\\\\implies x = \frac{-62 }{2}\;\;\;\;or\;\;\;\;x= \frac{60 }{2}\\\\\implies x = -31\;\;\;\;or\;\;\;\;x= 30\)

Sice x is a page number, it cannot be negative

⇒ x = 30 and

x + 1 = 31

The two pages Josiah can see are pg.30 and pg.31

Type I error is generally worse than a Type II error in all of these scenarios, as it can have more severe consequences.

The Null Hypothesis is a statement that assumes that there is no significant difference or effect between two groups or variables. The Alternative Hypothesis is a statement that assumes that there is a significant difference or effect between two groups or variables.

Type II error: We conclude that the drug does not cure a cold, but it actually does.

Ramifications: If we make a Type I error, we may give the drug to people who do not need it, which can have negative side effects. If we make a Type II error, people who could have benefited from the drug will not receive it.

Answer:

5 hours

Step-by-step explanation:

Let's express each scenario as a function in a slope-intercept form, y = mx + b,

Where,

y = total amount of water

x = number of hours

m = rate of at which water is drained or filled per hour

b = initial quantity of water in the tank

✔️Equation for Tank A:

m = 2 gallons/hour = 2

b = 100 gallons = 100

Substitute m = 2 and b = 100 into y = mx + b:

y = 2x + 100

✔️Equation for Tank B:

m = 6 gallons/hour = -6 (this is negative 6 because water drains)

b = 140 gallons = 140

Substitute the values into y = mx + b

y = -6x + 140

✔️Set the two equation equal together to determine the number of hours (x) that must pass for the total amount of water (y) in tank A and tank B to be the same.

2x + 100 = -6x + 140

Collect like terms

2x + 6x = -100 + 140

8x = 40

Divide both sides by 8

x = 40/8

x = 5

Therefore, 5 hours must pass for the total amount of water in both tanks to be the same.

Answer:

bagel $1.25

Step-by-step explanation:

Let the price of a bagel = b.

A latte costs 3 times as much as a bagel, so the price of a latte is 3b.

4b = 5

b = 1.25

3b = 3.75

Answer:

bagel $1.25

latte: $3.75

Answer: A bagel cost 1.25$ and a latte cost 3.75$

Step-by-step explanation:

Let a latte be y

Let a bagel be x

3x = y   Total cost = 5$

A bagel is x, plus the 3x

4x = 5

Hello!

The variable of interest is:

X: Number of people that support the candidate.

You need to calculate the sample size to estimate the population proportion of supporters given a confidence level of 99% and a margin of error of 4%

The margin of error of the confidence level for the population proportion is

d= \(Z_{1-\alpha /2}\) * \(\sqrt{\frac{p'(1-p')}{n} }\)

From this formula you have to clear the value of n:

\(\frac{d}{Z_{1-\alpha /2}}\)= \(\sqrt{\frac{p'(1-p')}{n} }\)

\((\frac{d}{Z_{1-\alpha /2}})^2\)= \(\frac{p'(1-p')}{n}\)

\(n*(\frac{d}{Z_{1-\alpha /2}})^2\)= \(p'(1-p')\)

n= \(p'(1-p') * (\frac{Z_{1-\alpha/2}}{d} )^2\)

\(Z_{1-\alpha/2}= Z_{0.995}= 2.586\)

sample proportion "p'" since there is no sample information, nor any previous information is known, you have to consider it as the "worse case scenario" and use the value of p'= 0.50

d= 0.04

\(n= p'(1-p') * (\frac{Z_{1-\alpha/2}}{d} )^2= 0.5*0.5*(\frac{2.586}{0.04} )^2= 1044.9= 1045\)
