Answer:
a. committed a type 1 error
Step-by-step explanation:
The correct option is - a. committed a type 1 error
Reason -
Type 1 error occurs when a true null Hypothesis is rejected
Type 2 error occurs when a false null Hypothesis is accepted
Now,
Let us state that,
The null hypothesis and alternate hypothesis is
H0 : There is no difference between the mean lifetimes of the new and old designs
H1 : There is a difference between the mean lifetimes of the new and old designs
Now,
As there is no difference between the mean lifetimes of the new and old designs.
⇒ The null hypothesis is true.
But p value suggests that null hypothesis should be rejected
∴
We have committed a Type 1 error that is rejecting a true null hypothesis.
So,
The correct option is - a. committed a type 1 error

Give your answer in terms of pi.
9514 1404 393
Answer:
10π meters
Step-by-step explanation:
The circumference of the island is given by the formula ...
C = πd
where d represents the diameter of the circle.
Halfway around is half the circumference, so the distance the penguin swam is ...
1/2C = (1/2)π(20 m) = 10π m
The penguin swam 10π meters.
Answer:
10pi
Step-by-step explanation:
The circumference of the island is given by the formula ...
C = πd
where d represents the diameter of the circle.
Halfway around is half the circumference, so the distance the penguin swam is ...
1/2C = (1/2)π(20 m) = 10π m

4. Write an equation of a line that passes
through the points (-5, -11) and (-2,1).
Answer:
y=4x+9
Step-by-step explanation:
m=(y2-y1)/(x2-x1)
m=(1-(-11))/(-2-(-5))
m=(1+11)/(-2+5)
m=12/3
m=4
y-y1=m(x-x1)
y-(-11)=4(x-(-5))
y+11=4(x+5)
y=4x+20-11
y=4x+9

The temperature at noon is 7 less than twice the temperature at 6:00 a.m. At noon it is 61 degrees. The temperature at 6:00 a.m. is t degrees. what is the temperature at 6:00 a.m.?
Answer:
34 degrees
Step-by-step explanation:
The equation that represents this situation is
2t - 7 = 61
to solve, start by adding 7 to both sides
2t = 68
then divide both sides by 2
t = 34

You deposit $2700 in an account that pays 3% annual interest compounded weekly. How much money is in the account after 5 years?
Answer:
A = $3136.86
Step-by-step explanation:
Given the following data;
Principal = $2700
Interest rate = 3% = 3/100 = 0.03
Number of times = 52
Time = 5 years
To find the future value, we would use the compound interest formula;
[tex] A = P(1 + \frac{r}{n})^{nt}[/tex]
Where;
A is the future value.
P is the principal or starting amount.
r is annual interest rate.
n is the number of times the interest is compounded in a year.
t is the number of years for the compound interest.
Substituting into the equation, we have;
[tex] A = 2700(1 + \frac{0.03}{52})^{52*5}[/tex]
[tex] A = 2700(1 + 0.0005769)^{260}[/tex]
[tex] A = 2700(1.0005769)^{260}[/tex]
[tex] A = 2700(1.1618)[/tex]
A = $3136.86
Raul wants to buy a new bike from a store having a 10% off sale on
all bikes. The bike he wants has a sale price of $135. Write and solve
an equation to find the original price, b, of the bike.
by
Answer:
p = $150
Step-by-step explanation:
Let p represent the original price. Then 10% of that is the discount: 0.10p.
The price after discount is 90% of the original price, or (1.00-0.10)p = 0.90p = $135. We next solve this equation for p: 0.90p = $135, or p = $150.

In the sketch below, two parallel lines are cut by a transversal.
Answer:
m<1 = 150°
Step-by-step explanation:
Given:
m<1 = (4x + 50)°
m<2 = (7x - 25)°
Required:
m<1
Solution:
To find m<1, we need to create an equation that will enable us determine the value of x.
Thus,
4x + 50 = 7x - 25 => corresponding angles are congruent to each other
4x + 50 - 7x = 7x - 25 - 7x (subtraction property of equality)
-3x + 50 = - 25
-3x + 50 - 50 = -25 - 50 (substraction property of equality)
-3x = -75
-3x/-3 = -75/-3 (division property of equality)
x = 25
✅m<1 = (4x + 50)°
Plug in the value of x
m<1 = 4*25 + 50 = 100 + 50
m<1 = 150°

Answer:Your left hand side evaluates to:
m+(−1)mn+(−1)m+(−1)mnp
and your right hand side evaluates to:
m+(−1)mn+(−1)m+np
After eliminating the common terms:
m+(−1)mn from both sides, we are left with showing:
(−1)m+(−1)mnp=(−1)m+np
If p=0, both sides are clearly equal, so assume p≠0, and we can (by cancellation) simply prove:
(−1)(−1)mn=(−1)n.
It should be clear that if m is even, we have equality (both sides are (−1)n), so we are down to the case where m is odd. In this case:
(−1)(−1)mn=(−1)−n=1(−1)n
Multiplying both sides by (−1)n then yields:
1=(−1)2n=[(−1)n]2 which is always true, no matter what n is

Answer:
D as 32 divided by 8 is 4
Step-by-step explanation:
A quotient is a result obtained by dividing one quantity by another.
Answer:
The second choice is the correct answer. d/8=4
Step-by-step explanation:
if something is a quotient it means it is the solution of a division problem. So we know it cant be the first. the last one doesn't make sense because it says that 8 and a number d equals 4 so it cant be that 8*4=d. that also goes for the third problem because it has to equal 4 and that equals d not 4.
To find this out we see that because it is the quotient of a number and 8 is 4, that means that we have to have a number divided by 8, the only one with that is the second one.

Step-by-step explanation:
The time it takes to drive to Myrtle Beach varies inversely with the speed you drive. If it takes you 4 hours to reach Myrtle Beach when driving at a speed of 60 mph, how much time would it take if you drove at a speed of 80 mph?
If you drove at 80mph it would take you approximately 3 hours
This is because 60 is 75% of 80 and 3 hours is 75% of 4 hours.
25% of 4 hours is 1 hour
4 hours - 1 hour = 3 hours

It depends on the speed the car is going. If you are going 1 MPH you will drive a single mile per hour, but 2 MPH is 2 miles per hour. That's where the term "MPH" comes in, it tells you how many miles you will be driving per hour.
MPH = Miles Per Hour
