A bag of apples weighs 7 2/7
pounds. A crate of bananas is 5 times as heavy as the apples. What is the total weight of the fruit?
Answer:
43.71428571
Step-by-step explanation:
First, convert 7 2/7 into an improper fraction: 51/7
Second, multiply 51/7 by 5: 255/7
Third, add 255/7 and 51/7 to get 306/7
306/7 = 43.71428571
A hemispherical tank is filled with water and has a diameter of 12 feet. If water weighs 62.4 pounds per cubic foot, what is the total weight of the water in a full tank, to the nearest pound?
Answer:
The total weight = 1286 × 62.4 = 80246 pounds.
Step-by-step explanation:
The formula of the volume of the sphere is
V = 4/3×π×r³
Given
d = 17 feet
d = 2r
r = d/2 = 17/2 = 8.5 feet
V = 4/3×π×r³
Since we need half of the volume as it is a hemispherical tank.
= 1286 ft³
Given that the weighs 62.4 pounds per cubic foot
Thus, the total weight = 1286 × 62.4 = 80246 pounds.
Suppose an Oklahoman comes to Texas to go turkey hunting. He takes up camp 150 meters from the base of a cliff. When he sees a turkey he raises his shotgun, shoots, but misses (being a poor shot).

A student believes that a certain 6-sided number cube, with the numbers 1 to 6, is unfair and is more likely to land with a 6 facing up. The student rolls the cube 100 times and lands with 6 facing up 20 times. The P-value for the test of the hypotheses, H0:p=0.17 and Ha:p>0.17, is 0.19. What is the correct conclusion given a=0.05?
Because the P-value is less than a=0.05, the student should reject H0.
Because the P-value is less than a=0.05, the student should reject H0.
Because the P-value is greater than a=0.05, the student should reject H0.
Because the P-value is greater than a=0.05, the student should fail to reject H0.
Answer:
third one
Step-by-step explanation:
To find the p-value of a data set, we can use the rejection region data to predict where the answer will lie.
P-ValueTo find the p-value of this data set, let's write out the data given in the question.
Data;
H_o = p = 0.17Ha = p>0.17Technically, the p-value is greater that the Ha and this affect the data significantly.
Since the p-value is greater than the ha value, we can accept that the value of H_o and assume the student will reject the H_o

Step-by-step explanation:
A spinner is divided into five colored sections that are not of equal size: red, blue, green, yellow , and purple. The spinner is spun several times, and the results are recorded below: Spinner Results Color Frequency 18 15 Red Blue Green Yellow Purple 20 18 13 Based on these results , express the probability that the next spin will land on purple as a decimal to the nearest hundredth.
Answer:
0.15
Step-by-step explanation:
The probability would be the amount of times the pointer landed on purple divided by the total times the pointer was spun.
This would be 13/(18+15+20+18+13) = 13/84 = 0.15476
The probability that the next spin will land on purple nearest hundredth will be 0.15.
What is probability?Its fundamental concept is that someone will nearly surely occur. The proportion of positive events in comparison to the total of occurrences.
Then the probability is given as,
P = (Favorable event) / (Total event)
The table is given below.
Color Frequency
Red 18
Green 15
Blue 20
Yellow 18
Purple 13
Based on these results, the probability that the next spin will land on purple in decimal to the nearest hundredth is calculated as,
P = 13 / (18 + 15 + 20 + 18 + 13)
P = 13 / 84
P = 0.15
The probability that the next spin will land on purple nearest hundredth will be 0.15.

Answer:
x = 3.6
B. {7.88}
Step-by-step explanation:
[tex]\frac{6}{x}= \frac{10}{6}[/tex]
x · 10 = 6 · 6
10x = 36
10x ÷ 10 = 36 ÷ 10
x = 3.6
[tex]\frac{9}{8} =\frac{x}{7}[/tex]
8 · x = 9 · 7
8x = 63
8x ÷ 8 = 63 ÷ 8
[tex]x=7\frac{7}{8}[/tex] or x = 7.875
7.875 rounded to the nearest tenth is 7.88.
