pentagon [3]3 years ago

4 0

Answer:

9

Step-by-step explanation:

1/2 bh (b1+b2)
Count all the squares for the base (6 squares)
Half it bc 1/2bh, which is not 3(h)
Now count the amount of squares to the top of it from the bottom (3 as well)
Now the problem is 3(3) which is 9.
So, the answer is 9

Hope this helps! Comment on it if you need more explanation!:)

A cylinder has a volume of 96 pi cubic centimeters and a diameter of 12 centimeters. What is the height of the cylinder in centi

jonny [76]

Answer:

2 2/3 cm

Step-by-step explanation:

The volume of a cylinder is given by

V = pi r^2 h

We know the volume =96 pi and the diameter is 12

We want the radius

r =d/2 = 12/2 =6

96 pi = pi * (6)^2 h

96 pi = 36 pi h

Divide each side by 36 pi

96 pi/36 pi = 36pi h / 36 pi

8/3 = h

Changing from an improper fraction to a mixed number

2 2/3 = h

Last year, 46% of business owners gave a holiday gift to their employees. A survey of business owners indicated that 20% plan to

alisha [4.7K]

Answer:

Part a: So the number of business owners giving holiday gift to their employees from survey is 12.

Part b: p-value is 0.00003

Part c: value of p is less that a we reject the null hypothesis.

Step-by-step explanation:

Part a

number of business owners=20% x n

number of business owners= 0.2x 60

number of business owners=12

Part b

H0: p=0.46

H1: p<0.46

Here

n=60, $\hat{p}$ =0.2, p=0.46

So test statistics is given as

$z=\frac{\hat{p}-p}{\sqrt{\frac{p(1-p)}{n}}}\\z=\frac{0.20-0.46}{\sqrt{\frac{0.46(1-0.46)}{60}}}\\z=\frac{-0.26}{0.064}\\z=-4.04$

p-value is P(z<-4.04)= 0.00003

Part c

As value of p is less that a we reject the null hypothesis.

Tell whether the sequence is arithmetic. If it is, what is the common difference? (1 point)

larisa [96]

Since an arithmetic sequence is a sequence of numbers and the difference of any two successive members of the sequence is a constant

So this question is arithmetic because it keep minus by 7

from 19 - 7 = 12

12 - 7 = 5

5 - 7 = -2

so common difference is -7

or you can check with arithmetic formular as

$a_{n}$ = $a_{1}$ + (n−1)d

I will just put in the 4th term which is -2 and n will equal to 4

and $a_{1}$ is the 1st term which is 19

-2 = 19 + (4−1)d

-2 - 19 = 3d

d = $\frac{-21}{3}$

d = -7

A club collected $1,085.00. If 75% of that came from membership dues, how much money came from sources other than membership?

bagirrra123 [75]

Answer:

100% - 75% = 25% so the answer is 25% of 1085 = 0.25 * 1085 = $271.25.

Estimate the time it would take you to drive 361 miles at 42 miles per hour. Round to the nearest hour.

polet [3.4K]

Answer:

It would take you 9 hours

Step-by-step explanation:

Speed (s) = Distance (d) / Time (t)

given that; Speed = 42 miles/hour

Distance = 361 miles

42 miles/hour = 361 miles / Time (t)

Time (t) * 42 miles/hour = 361 miles

Time (t) = 361 miles / 42 miles/hour

Time (t) = 8.59 hours

≈ 9 hours (to the nearest hour)
