Answer:
2.1 ft³
Step-by-step explanation:
Put the given radius and height into the volume formula and do the arithmetic.
V = 1/3πr²h
V = 1/3(3.14159)(1 ft)²(2 ft) ≈ 2.094 ft³
Rounded to tenths, this is 2.1 cubic feet.
__
The picture cuts off your rounding requirements. If it is hundredths, you need to use 2.09 ft³. If it is thousandths, your answer will depend on the value of pi you are asked to use.

4 games at 2/3 chance for each = 16/27
We look at 1/3 x 1/3 = 11/ 20
we look at 2/3 x 2/3 = 0.444 = 22/50 = 11/25
The other two games are
1/3 x 2/3 = 0.22 + 0.22 = 0.44
0.44 = 11/25
+ 3/20
= 16/27

Step-by-step explanation:
7.
Add the lengths of the sides. Each square on the grid has side 2 units.
9 + 4 + 4 + 8 + 11 + 3 + 2 + 15 = 56
8.
Find the lengths of the bases and the height of the trapezoid. Each square on the grid is 2 units.
Area of trapezoid = (1/2)(b1 + b2)h
area = (1/2)(15 + 11)(9) = 117
5. Casey's bank account offers him 2% interest every year, given by the equation
g(x)= 1.02. If Casey deposits $5,625 in his bank account, which equation
represents the amount of money that will be in his account after 2 years?
Answer:
Casey will have 5852.25 in his bank account after 2 years.
Step-by-Step Explaination:
2%=0.02
0.02*5625=112.5
112.5+5625=5737.5
0.02*5737.5=114.75
114.75+5737.5=5852.25

Find a value of k such that kx2 + 12x − 4 = 0 has one real-number solution. Explain.
Answer: if x is to the 2 power then
kx^2+12x-4=0 Add 4 to the both sides
kx^2+12x=4 Divide both sides by 12
kx^2=1/3x square root the both sides
k=0.6x

With double-digit annual percentage increases in the cost of health insurance, more and more workers are likely to lack health insurance coverage (USA Today, January 23, 2004). The following sample data provide a comparison of workers with and without health insurance coverage for small, medium, and large companies. For the purposes of this study, small companies are companies that have fewer than 100 employees. Medium companies have 100 to 999 employees, and large companies have 1000 or more employees. Sample data are reported for 50 employees of small companies, 75 employees of medium companies, and 100 employees of large companies.
Health Insurance
Size of Company Yes No Total
Small 33 17 50
Medium 68 7 75
Large 88 12 100
Conduct a test of independence to determine whether employee health insurance coverage is independent of the size of the company. Use = .05.
1. Compute the value of the 2 test statistic (to 2 decimals).
2. The p value is :_____.
a. less than .005
b. between .005 and .01
c. between .01 and .025
d. between .025 and .05
e. between .05 and .10
f. greater than .10
3. What is your conclusion?
a. health insurance coverage is not independent of the size of the company
b. Cannot reject the assumption that health insurance coverage and size of the company are independent
4. The USA Today article indicated employees of small companies are more likely to lack health insurance coverage. Calculate the percentages of employees without health insurance based on company size (to the nearest whole number).
Small %
Medium %
Large %
Answer:
1. χ² = 15.3902
2. The p value is :_____.a. less than .005
3. Conclusion
a. health insurance coverage is not independent of the size of the company
4. The percentages of employees
Small %= 33/50= 0.66
Medium %= 68/75 = 0.91
Large %= 88/100= 0.88
Step-by-step explanation:
1) We set up our null and alternative hypothesis as
H0: the employee health insurance coverage is independent of the size of the company
against the claim
Ha: the employee health insurance coverage is not independent of the size of the company
2) the significance level alpha is set at 0.05
3) the test statistic under H0 is
χ²= ∑ (O - E)²/ E where O is the observed and E is the expected frequency
which has an approximate chi square distribution with ( 3-1) (2-1)= 2 d.f
4) Computations:
Under H0 , the observed frequencies are :
Observed Expected E (O-E) (O-E)² (O-E)²/E
33 42 -9 81 1.928
68 63 5 25 0.3968
88 84 4 16 0.1904
17 8 9 81 10.125
7 12 -5 21 1.75
12 16 -4 16 1
15.3902
Expected Values are calculated using the formula :
Row Total * Column Total / sample size
E1= (33+17) (33+ 68+88)/ 50+75+100= 42
E4= (33+17) (17+ 7+ 12)/ 50+75+100=8
E2= (68+7) (33+ 68+88)/ 50+75+100= 63
E5= (68+7) (17+ 7+ 12)/ 50+75+100= 12
E3= (88+12) (33+ 68+88)/ 50+75+100= 84
E6= (88+12) (17+ 7+ 12)/ 50+75+100= 16
5) The critical region is χ² ≥ χ² (0.05)2 = 5.99
6) Conclusion:
The calculated χ² = 15.3902 falls in the critical region χ² ≥ 5.99 so we reject the null hypothesis that the employee health insurance coverage is NOT independent of the size of the company.
2. The p value is :_____.
a. less than .005
The p-value is .000385.
3. Conclusion
a. health insurance coverage is not independent of the size of the company
4. The percentages of employees
Small %= 33/50= 0.66
Medium %= 68/75 = 0.91
Large %= 88/100= 0.88

A rectangular swimming pool has a width of 42 ft and a diagonal of 70 ft. Find the length of the pool.
Answer:
56 feet.
Step-by-step explanation:
The formula for finding the length of a rectangle, given the diagonal and the width is [tex]\sqrt{d^2 -{w^{2}[/tex]. So, [tex]\sqrt{4900 - 1764[/tex]. If you put this thing in the calculator you get 56.

An aquarium is to be drained. The aquarium is shaped like a rectangular prism with length 40 in, width 22 in, and height 16 in. Suppose
water is pumped out of the aquarium at a rate of 704 in per minute. If the aquarium starts completely full, how many minutes does it take
to empty the aquarium?
9514 1404 393
Answer:
20 minutes
Step-by-step explanation:
The volume is given by ...
V = LWH
V = (40 in)(22 in)(16 in) = 14,080 in³
If water is removed at the rate of 704 in³/minute, the time to remove it all is ...
t = quantity/rate = (14,080 in³)/(704 in³/min) = 20 min
It takes 20 minutes to empty the aquarium.
Use the formula SA = 2(lw) + 2(wh) + 2(lh) to find the surface area for a rectangular prism with the L of 2.1 yd, a width w of 1.86 yd, and a high h of 6 yd.
Answer:
SA = 19.92 yd²
Step-by-step explanation:
SA = 2(2.1) + 2(1.86) + 2(6) = 19.92 yd²
