Answer:
The number of adult admissions was 12 and the the number of child admissions was 17
Step-by-step explanation:
Let
a ----> represent the number of adult admissions
c ----> represent the number of child admissions
we know that
A group of 29 people attending the zoo paid a total of $222 in admission fees
so
----> equation A
----> equation B
Solve using the substitution method
substitute equation A in equation B
solve for c
Find the value of a
therefore
The number of adult admissions was 12 and the the number of child admissions was 17
13. You add the 8 and the 5
Answer:
Because the absolute value of the test statistic is <u>less than</u> the positive critical value, there <u>is not</u> enough evidence to support the claim that there is a linear correlation between the weights of discarded paper and glass for a significance level of α = 0.05.
Step-by-step explanation:
The correlation matrix provided is:
Variables Paper Glass
Paper 1 0.1853
Glass 0.1853 1
Te hypothesis for the test is:
<em>H</em>₀: <em>ρ</em> = 0 vs. <em>H</em>₀: <em>ρ</em> ≠ 0
The test statistic is:
<em>r</em> = 0.1853 ≈ 0.185
As the alternate hypothesis does not specifies the direction of the test, the test is two tailed.
The critical value for the two-tailed test is:
The conclusion is:
Because the absolute value of the test statistic is <u>less than</u> the positive critical value, there <u>is not</u> enough evidence to support the claim that there is a linear correlation between the weights of discarded paper and glass for a significance level of α = 0.05.
Answer: Warren drank 1 7/15 Liters of water altogether
Step-by-step explanation:
Step 1
Amount of water drank before jogging = 4/5 liters
Amount of water drank after jogging =2/3 liters
Amount of water drank altogether =Amount of water drank before jogging +Amount of water drank after jogging
Step 2
Amount of water drank altogether = 4/5 + 2/3
The LCM of 5 and 3 gives 15 , so we have the denominator becoming 15,
4/5 + 2/3 = / 15
15 divided by 5 gives 3 multiplied by 4 gives us 12 and also 15 divided by 3 gives 5 multiplied by 2 gives 10 , such that we have
12 + 10 / 15
= 22/ 15
=1 7/15
4 units because 5 plus 5 equals 10 and 4 plus 4 equals 8
10 plus 8 equals 18
