Answer:

The Distributive property states that

a(b+c)=ab+ac

Now, let's simplify:

6(3a-4)

18a-24

Answer:

**Answer:**

first you multiply 6 and 3a which equals 18a. Then you multiply 6 and 4 which equals 24. So in the end it should look like: 18a-24

**Answer: **1.88

**Step-by-step explanation:**

**The confidence interval for population mean is given by :-**

**Given : **Significance level :

Critical value :

By using the standard normal distribution table for z, we find the critical value of corresponds to the p-value 0.03.

**Hence, the z-value that was used in the computation must be 1.88 .**

What is the area of the circle using π = 3.14?

113.04 in2

452.16 in2

1,017.36 in2

4,069.44 in2

**Answer:**

1017.36 in²

**Step-by-step explanation:**

__Information we need to know:__

Radius = diameter ÷ 2

Area of circle = πr²

**1) Find the radius of the circle**

We have to make sure the we are using the radius of the circle instead of the diameter as the formula using the value of __r__. If we were to use the diameter our answer would be wrong.

- 36 ÷ 2 = 18

**2) Find the area**

To find area we can distribute the numbers given into the formula...

- 3.14 (π) x 18 (r)² = 1017.36

**Hope this helps, have a lovely day! :)**

Answer:

A = 1,017.36 in²

The answer is option C

Step by step solved:

The formula to calculate the area of a circle is

A = πr²,

where A is the area and r is the radius of the circle. In this case, the diameter of the circle is given as 36 inches, so the radius is half of that, which is 18 inches.

Using the value of π as 3.14, we can plug in the values and calculate the area as follows:

A = πr²

A = 3.14 x 18²

A = 3.14 x 324

A = 1,017.36 in²

Therefore, the area of the circle with a diameter of 36 inches using π = 3.14 is 1,017.36 in². The answer is option C

**This gives:**

**Take arccos of both sides**

Answer:

The test statistic is -2.5

Yes, I can reject the null hypothesis at 5% significance level.

Step-by-step explanation:

Null hypothesis: The average number of sardines in a can is 9.75

Alternate hypothesis: The average number of sardines in a can is greater than 9.75

Test statistic (z) = (sample mean - population mean) ÷ sd/√n

sample mean = 9.75

population mean = 10

sd = 1

n = 100

z = (9.75 - 10) ÷ 1/√100 = -0.25 ÷ 0.1 = -2.5

The test is a one-tailed test. At 5% significance level, the critical value is 1.645

Conclusion:

Reject the null hypothesis because the test statistic -2.5 is less than the critical value 1.645

please!! I need it right jnow

**Answer:**

62.8 ft (of edging)

**Step-by-step explanation:**

We need to find the circumference of this circle, using C = 2(pi)r.

Here, C = 2(3.14)(10 ft) = 62.8 ft (of edging)

**Answer:**

**63 feet is needed to go around the garden.**
