Answer:
17
Step-by-step explanation:
3 1/2+3 1/2=5 which is 40 min
5=40mins
5+3 1/2=81/2
1 hour=8 1/12
8 1/2+8 1/2= 17
17 in two hours
Answer:
Null Hypothesis 
years
Alternative hypothesis 
years
Step-by-step explanation:
Hypothesis is a tentative guess. In a null hypothesis, 
we state that there's no statistical significance between the variables. For alternative hypothesis, 
it's stated that there's significant statistical relation between the provided variables. In this case, the null Hypothesis is years and the alternative hypothesis is years
We can decide to accept or reject either null hypothesis or alternative hypothesis
Answer:
45 is 2 standard deviations below the mean (60).
Step-by-step explanation:
2 standard deviations below the mean is equivalent to what you have written here.
To answer this, start with the mean (60) and subtract 2 standard deviations (2 times 7.5). Subtract, as indicated:
60 - 2(7.5) = 60 - 15 = 45
Answer:
<h2>The range: {-6, -10, -14, -18}</h2>
Step-by-step explanation:
Put the values of x from the domain to the equation of a function y = 4x - 2:
for x = -1
y = 4(-1) - 2 = -4 - 2 = -6
for x = -2
y = 4(-2) - 2 = -8 - 2 = -10
for x = -3
y = 4(-3) - 2 = -12 - 2 = -14
for x = -4
y = 4(-4) - 2 = -16 - 2 = -18
Answer:
The area of the rectangle in terms of 'x' = 13x
Step-by-step explanation:
Using the perimeter formula to find the width w.
Dividing both sides by 2
as P = 30 cm
cm
Using the formula of the rectangle area
substitute w = 13 and l = x in the formula
Therefore, the area of the rectangle in terms of 'x' = 13x
