Answer:
In 10 seconds, the garden hose will emit 15 quarts of water.
Step-by-step explanation:
The amount of water emitted by the garden hose over time can be expressed as a ratio: 9/6, or 9 quarts of water for every 6 seconds of time. We can then simplify this ratio to 3/2, or 3 quarts of water for every 2 seconds of time. Since the ratio will remain constant, or the same, over time, we can set up an equivalent ratio, or fraction to find the amount of water emitted in 10 seconds: 3/2 = x/10. We look at the denominators and see that 2 x 5 = 10. In order to make the ratios equivalent, we would also multiply the numerator by 5: 3 x 5 = 15, which gives us the amount of water emitted in 10 seconds.

Answer:
yes
Step-by-step explanation:
For some integer n, the squirrel lands on numbers that are ...
5n +6
We want to see if n is an integer when ...
5n +6 = 101
5n = 95
n = 19 . . . . yes, an integral number of jumps will get the squirrel to 101
Answer:
This gives us a pair of simple equations:
100percent =150(1). xpercent =114(2).
therefore, 114 is 76percent of 150
Answer:
We conclude that that there is enough evidence to support the claim mean credit card debt for individuals is greater than $5,100.
Step-by-step explanation:
We are given the following in the question:
Population mean, μ = $5,100
Sample mean, 
= $ 5,270
Sample size, n = 27
Alpha, α = 0.10
Sample standard deviation, s = $550
a) First, we design the null and the alternate hypothesis
We use one-tailed t test to perform this hypothesis.
b) Formula:
Putting all the values, we have
c) Now,
Since,
d) We fail to accept the null hypothesis, and accept the alternate hypothesis.
e) We conclude that that there is enough evidence to support the claim mean credit card debt for individuals is greater than $5,100.
