Answer:
biking at a moderate speed of 12 to 13.9 miles per hour will cause a 155-pound person to burn 298 calories in 30 minutes. At a faster rate of 14 to 15.9 miles per hour, a person of the same weight will burn 372 calories.

There will be 9 pairs of socks with one sock with no match
19 (socks all together) ÷ 2 (how many are in a pair) = 9 (how many actual pairs) with a remainder of 1 (the odd sock out)
Answer:
A
Step-by-step explanation:
Given
3![(1.5)^{t}](https://tex.z-dn.net/?f=%281.5%29%5E%7Bt%7D)
When the culture was created t = 0, thus
3
= 3 × 1 = 3
That is there were initially 3 bacteria in the culture → A
Answer:
Option A
Step-by-step explanation:
The set of values for which y is a function of x is the set where each x-value has exactly on y-value. No x-value has more than 1 y-value.
✅Option A: y is A FUNCTION of x because it has exactly one y-value assigned to each x-value.
❌Option B: y is NOT a function of x because there are two y-values, 4 and 2, that are assigned to one x-value, -1.
❌Option C: y is NOT a function of x because there are two y-values, 10 and 12, that are assigned to one x-value, 1.
❌Option D: y is NOT a function of x because there are two y-values, 2 and 4, that are assigned to one x-value, -1.
Answer:
190
Step-by-step explanation:
Data provided in the question:
Confidence level = 99%
Therefore,
α = 1% = 0.01
[ from standard normal table ]
z-value for
= 2.58
Margin of error, E = $0.06
Standard deviation, σ = $0.32
Now,
n = ![(\frac{z_{0.005}\sigma}{E})^2](https://tex.z-dn.net/?f=%28%5Cfrac%7Bz_%7B0.005%7D%5Csigma%7D%7BE%7D%29%5E2)
Here,
n is the sample size (or the minimum number of gas stations )
on substituting the respective values, we get
=
=
= 13.76²
= 189.3376 ≈ 190
Hence,
minimum number of gas stations that she should include in her sample is 190
