Answer:
At least 7 girls: 0.5^7 OR 0.0078125
At least 8 girls: 0.5^8 OR 0.00390625
Answer:
43242443534138
Step-by-step explanation:
Simple...
Which line shows the first error in the solution?
Line 3
This said, because...
5x-25=15
It'd be adding not subtracting-->>
5x-25=15-25 (No)
5x-25=15
+25 +25
5x=40 (Yes)
Thus, your answer.
Answer:
The targeted population is USA residents who died of heart disease.
Step-by-step explanation:
According to this case, "the death rates due to heart disease among the smokers and nonsmokers are compared to see if smoking causes heart disease." This implies that the study targets those USA residents who died of heart disease to find out if the cause of death can be traced to heart disease caused by smoking or not. The main concentration for the study defines the targeted population. It is this group of residents who died of heart disease that is the population of interest. This means that the targeted population is a certain group of the population that share similar characteristics, especially death resulting from heart disease caused by smoking.
Use these variables to make an equation-
y is the total amount.
$50 is where you start charging(y intercept, variable b).
x is how many visits Marsha made.
The equation can be in slope-intercept form (y=mx+b)-
$144=$2x+50
Solve for x using inverse operations.
Subtract 50 from both sides-
144-50=2x+50-50
94=2x
Divide 2 from both sides-
94/2=2/2
x=47
Marsha made 47 visits to the health club.
