There are 5 feet and 2 inches in 62 inches. Hope this helps!
A. Since the ribbons come in rolls of 15, we need groups of 15 yards. Since we are told that we have 322 yards. We have to find a way to express this number into groups of 15. To do that we can simply divide. 322 /15 = 21.466... since we can’t have one fourth of a role, we have to buy a whole one to be able to get that .4. So, Quincy needs 22 roles.
B. Twice means two times something. So all you do is multiply 322( the number of yards Quincy needs) times 2 = 644. Alice needs 644 yards of ribbon.
C. All you have to do is break 285 yards into 3 groups so: 285/3= 95. So, Elena needs 95 yards of yellow, 95 yards of red, and 95 yards of blue.
Hope this helped and pls mark as brainliest!

Step-by-step explanation:
Answer:
(a) State the appropriate null and alternative hypotheses to assess whether women are taller today.
Solution:
Definition of null hypothesis : The null hypothesis attempts to show that no variation exists between variables or that a single variable is no different than its mean. it is denoted
Alternative Hypothesis: In statistical hypothesis testing, the alternative hypothesis is a position that states something is happening, a new theory is true instead of an old one (null hypothesis).
We are given that The mean height of women 20 years of age or older was 63.7 inches.
So, null hypothesis :
Alternative Hypothesis :
b)The P-value for this test is 0.16.
Solution: The p-value represents the probability of getting a sample mean height of 65.1 inches.
c) Write a conclusion for this hypothesis test assuming an alpha equals 0.10 level of significance.
Solution:
p- value = 0.16
Since the p - value is high .
So, we will accept the null hypothesis
So,
Hence The mean height is 63.7 inches
Hello!
7r/3s + 3r/4s =
= 4×7r/4×3s + 3×3r/3×4s =
= 28r/12s + 9r/12s =
= 28r+9r/12s =
= 37r/12s
Good luck! :)
