I think it’s C. Because
X ≤ 9and 9 is higher than -7 (sorry if I’m wrong)
Based on the figures above, the numbers of children that attended the park that day is 10,000.
<h3>What is the matrix equation about?</h3>
Fist we have to use the determinant to solve for c and as such:
=
= 100000/10
=10,000
Therefore, Based on the figures above, the numbers of children that attended the park that day is 10,000.

Answer:
(69.94, 72.06)
Step-by-step explanation:
Confidence Interval formula = Mean ± z × Standard deviation/√n
Mean = 71 ounces
Standard deviation = 2.8 ounces
z score = 95% confidence interval = 1.96
Confidence Interval = 71 ± 1.96 × 2.8/√27
= 71 ± 1.96 × 0.5388602512
= 71 ± 1.0561660924
71 - 1.0561660924
= 69.943833908 ounces
Approximately = 69.94 ounces
71 + 1.0561660924
= 72.0561660924 ounces
Approximately = 72.06 ounces
95% Confidence Interval = (69.94, 72.06).
So if makes $23.25 selling bread,
Take $23.25 and multiply it by 100.
23.25 x 100 = $2,325
Inez made $2,325
Jo made one tenth of what Inez made.
You multiply 2,325 by one tenth.
(one tenth) x 2,325 = 232.5.
So May made $23.25
Inez made $2,325
Jo made $232.5
