Answer:
h = 81
Step-by-step explanation:
19 = h/3 - 8
collect like terms
19 + 8 = h/3
27 = h/3
h = 27 x 3
h = 81

Step-by-step explanation:
Ratio of apples to strawberries in Angie's salad
= 4:5
= 36:45 <em>(because we multiplied both numerator and denominator by 9, to get the same denominator as the other ratio)</em>
Ratio of apples to strawberries in Salim's salad
= 7:9
= 35:45 <em>(because we multiplied both numerator and denominator by </em><em>5</em><em>, to get the same denominator as the other ratio)</em>
36:45 ≠ 35:45
So, ratio of apples to strawberries in Angie's salad ≠ ratio of apples to strawberries in Salim's salad.
36:45 > 35:45
So, ratio of apples to strawberries in Angie's salad < ratio of apples to strawberries in Salim's salad.
Octagon - 135 degrees
Decagon - 144 degrees
135 / 144 * 100% = 93.75%
Therefore it is 6.25% less

Answer:
Step-by-step explanation:
Set up hypotheses as
(Left tailed test at 5% level)
Sample mean = 53.4
Sample std dev s = 4.4
Sample std error = 4.4/sqrt 50 = 0.6222
Mean diff = 3.4
Test statistic = Mean diff/std error = 0.5464
(t test only can be used as population sigma is not known)
df = 50-1 =49
p value = 0.2939
Since p>0.05 we accept null hypothesis
