Answer:
16
Step-by-step explanation:
Answer:
<em><u>x=-2</u></em>
Step-by-step explanation:
<u>Let's solve your equation step-by-step.
</u>
<em>3x+9=x+5
</em>
<u>Step 1: Subtract x from both sides.
</u>
<em>3x+9−x=x+5−x
</em>
<em>2x+9=5
</em>
<u>Step 2: Subtract 9 from both sides.
</u>
<em>2x+9−9=5−9
</em>
<em>2x=−4
</em>
<u>Step 3: Divide both sides by 2.
</u>
<em>2x
/2=-4/2</em>
<em>x=−2
</em>
Answer: 38
Step-by-step explanation:
Since the polygons are similar, the corresponding sides are all in the same proportions.
x-2/4.5 = 16/2 = 48/6
<u>Solving for x</u>
Therefore, the value of x is 38
Answer:
H0 : P ≤ 0.12
H1 : P > 0.12
Step-by-step explanation:
12% = 12/ 100 = 0.12
Given the population proportion, P = 0.12
The claim is the alternative hypothesis, H1 ; which is to test if more than 12% of trees have been infested.
Hence, the alternative hypothesis will be ;
H1 : P > 0.12
The null hypothesis which is the initial truth is always the opposite of the alternative hypothesis, Therefore, we write our null as ;
The null hypothesis ; H0 : P ≤ 0.12
Therefore, we have :
H0 : P ≤ 0.12
H1 : P > 0.12
