The basic exponential parent function in this question is A, so choose Option A
Answer:
(0.5446, 0.6554)
Step-by-step explanation:
As the sample is sufficiently large, the formula is used to estimate the proportion shown in the attached image.
Where:
P: sample proportion = 0.6
n: Sample size = 300
: Confidence level = 0.95
α: Significance = 0.05
*
* Obtained from the normal standard table.
When introducing these values in the formula shown in the image we obtain:
Finally, the confidence interval is:
(0.5446, 0.6554)

The car salesman makes a base salary of $2,000. He also gets $1,000 for every car he sells. And it asks us, "<span>How much does he earn for each car sold?"
The variable x is how many cars he sold. In this one.
Now the equation is this: 2000 + 1000(1)
Now solve.
2000 = 1000(1) = 2000 + 1000 = 3000
So our car salesman would have made $3,000 in a month.</span>
Answer:
ΔABC and ΔA'B'C' are congruent, by the SSS rule of congruency
Step-by-step explanation:
The given parameters are;
The transformation undergone by triangle ABC = (x, y) → (x + 7, y + 3) to give triangle A'B'C'
Therefore, the points on triangle ABC are transformed by a translation of 7 units to the right and 3 units up to form triangle A'B'C'
Given that a translation transformation is a form of rigid transformation, we have;
The lengths of triangle ABC are congruent to the lengths of the sides of triangle A'B'C'
Therefore. ΔABC ≅ ΔA'B'C', by the Side-Side-Side (SSS) rule of congruency.
