Answer:
P = 2(21 + 3)
= 2(24)
=$48
Step-by-step explanation:
Add them all up.
s + 2(s+3) + 4s-5 = 148
s + 2s + 6 + 4s - 5 = 148
Group all s together and all numbers together 7s + 1 = 148
7s = 147
Divide by 7
s = 21
Plug s=21 back in for Petro
Answer:
One-way ANOVA
Step-by-step explanation:
One-way ANOVA(analysis of variance) a testing method in statistics that is used to compare the means of two or more independent samples, to check if the differences are statistically significant.
In this case, we have three groups which their various reaction time to caffeine is to be tested using the same testing method (amount of caffeine). Hence the appropriate test to use here is the one-way ANOVA

Step-by-step explanation:
Each person gets a haircut --> 3.15= 45
Answer:
58 degrees
Step-by-step explanation:
90 - 32 = 58
X% of 4 = x*4/100 = 0.04x
y% of 5 = x*5/100 = 0.05y
x% of 4 + y% of 5 = 0.04x + 0.05y
How you express a number, n, as percentage of 11?: [n/11]*100= 9.10n %
Then make n = 0.04x + 0.05y
9.10n %= 9.10[0.04x + 0.05y] %= (0.3656x + 0.455y)%
.
