Answer:
c) 70 toothbrushes per minute
Step-by-step explanation:
The table tells you that production is 140 toothbrushes in 2 minutes. Dividing toothbrushes by minutes gives you the "per minute" value:
(140 toothbrushes)/(2 minutes) = (140/2) toothbrushes/minute
= 70 toothbrushes/minute

The correct answer is C. Foci.
A hyperbola is defined as the flat open curve resulting from the intersection of a right circular cone from a plane not parallel to any of its origins. The line joining the foci of the hyperbola is called the base line.
The perpendicular to the middle of the baseline is called the center line. It becomes apparent that all points of the center line are equidistant from the foci.

A random variable X has a lognormal distribution if Y = ln X has a normal distribution. For this problem, assume that Y has a mean and standard deviation of 0.353 and 0.754
(a) What are the possible values X can take?
(b) What is the probability that X is between 1 and 2?
Answers
Answer:
Step-by-step explanation:
From the given information:
For X to be valid, the possible values of X should be greater than zero i.e. X > 0
If X obeys a lognormal distribution
Then; Y = In X
So,
Now,
[tex]E(X) = e^{0.353} + \dfrac{1}{2}(0.754)^2[/tex]
[tex]E(X) = 1.8913[/tex]
Also;
[tex]V(X) = e^{2 \times 0.353 + 2(0.754)^2} -e^{2\times 0.353 + (0.754)^2}[/tex]
V(X) = 2.7387
∴
SD(X) = 1.6549
[tex]P(1 < X < 2) = P(X < 2) - P(X < 1)[/tex]
= 0.108

The radius of a circle is 40 miles. What is the angle measure of an arc 9pi miles long?
Answers
Answer:
40.5°
Step-by-step explanation:
So this problem is a ratio setup. First, you have to calculate the total circumference of the circle using the following formula:
c = 2πr
Where c is the circumference, and r is the radius of the circle. Therefore:
c = 2π(40)
Simplify:
c = 80π
Now if the arc is 9π miles long, then it's a fraction of the whole circle, which is 360° . We can set this up as follows:
[tex]\frac{9\pi }{80\pi }[/tex] = [tex]\frac{x}{360}[/tex]
Now if we cross-multiply to solve for x:
(9)(π)(360) = (80)(π)(x)
When simplified dividing by 10π :
9*36 = 8x
Simplfy.
324 = 8x
Solve for x.
x = 40.5

x=12 Proportion should be 1 2/3
Step-by-step explanation:
To find PT, subtract 26 from 65= 39
26/39 is equal to 2/3, so 30/(4x-3) should also be equal to 2/3
30/(4x-3)=2/3 (Cross Multiply)
30*3=90
2(4x-3)=8x-6
8x-6=90 (Add 6 to both sides)
8x=96 (Divide 8 from both sides)
x=12

can someone explain this to me?? so im trying to find the scale factor of quadrilateral I to quadrilateral II and the answer is 1/2 but how does that make sense if quadrilateral I is smaller than Quad II? if we were to use the scale factor wouldnt it just divide our side lengths in half?
Answers
Answer:
the scale factor is 1/2 you are right and that is credible as the larger cd is 20 and smaller bc 10 which make out that it is half of the other Quad and the marking on the edge makes clear us that it is equal whatever the drawing is.
Step-by-step explanation:
BC=2CD
10x=20
x=10/20
x=1/2
if u want to find the other angle then it is 2 times of the smaller quad that will be:
AG=FE
15=2(15)=30
AB=ED
9=2(9)=18
GC=FC
13=2(13)=26
