5^2 + 15 = 40 Would be an answer
Answer:
D. Sarah does not have convincing statistical evidence to conclude that the population mean number of days for the plants to produce fruit is different from 87 days.
Step-by-step explanation:
The population mean, μ is given as 87
This population value is used to state the Null hypothesis ;
H0 : μ = 87
The alternative hypothesis is the opposite of the Null ; and hence, claims that the mean is different from the population mean, μ ≠ 87
H1: μ ≠ 87
The Decison level :
When Pvalue < α ; We reject the Null otherwise we fail to reject the null
The given p and α value :
P-value = 0.0752
α = 0.05
0.075 > 0.05 ; Hence ;
Pvalue > α ; We fail to reject the Null
We can thus conclude that there is not enough evidence to conclude that the population mean number of days for the plants to produce fruit is different from 87 days.
12 / 27 = 4/h Cross multiply
12h = 27 * 4 Notice top and bottom is equated to top and bottom of the two you have not yet used.
12h = 108 Divide by 12
h = 108 / 12
h = 9
C <<<<<-===== answer.
Answer:
x = 2
Step-by-step explanation:
Step 1: Write equation
3(x + 2) = 12
Step 2: Solve for <em>x</em>
- Distribute 3: 3x + 6 = 12
- Subtract 6 on both sides: 3x = 6
- Divide both sides by 3: x = 2
Step 3: Check
<em>Plug in x to verify it's a solution.</em>
3(2 + 2) = 12
3(4) = 12
12 = 12
