Answer:
a
Step-by-step explanation:
x + 16 = 64 |subtract 16 from both sides
x = 48
Answer:
No, a convenience sample was taken.Therefore, the sample may not be representative of all college students in terms of number of hours studied per week.
Step-by-step explanation:
One of the important conditions required in other to estimate the mean of the population from the confidence interval. Requires that the data must be a random Sample. This is to ensure that sample values are not biased and as such are representative of the larger group of data.
However, in the scenario described above, the sample chose. Are friend's of the student, this makes the data lack randomness as those who aren't friends to the student do not stand a chance of being selected. The sampling procedure employed is called convenience sampling.
Y= kx (k being a constant)
10= k × 4 k=5/2
y= 5x/2 The answer is C.
The equation that represents the situation will be (0.75x) + 0.8(x + 10) = 101
<h3>How to compute the equation?</h3>
From the information, Jared attempted x shots and made 75% of them. Zach attempted 10 more shots than Jared did and made 80% of them.
Therefore the equation that represents the situation will be:
= (0.75 × x) + 0.8(x + 10) = 101
= 0.75x + 0.8(x + 10) = 101.
Therefore, the equation that represents the situation will be (0.75x) + 0.8(x + 10) = 101
