Answer and Step-by-step explanation:
These two angles are vertical to each other, which means they are equal to each other,
Set them equal to each other to find x.
9x - 2 = 52
Add 2 to both sides of the equation.
9x = 54
Now divide both sides by 9.
x = 6
The value of x is 6.

Answer:
x=6
Step-by-step explanation:
The two angles are vertical angles, and are therefore congruent. Because of this, we can set both angles equal to each other.
9x-2=52
Add 2 to both sides.
9x=54
divide both sides by 9
x=6

Step-by-step explanation:
A play has two different male roles, two different female roles and two different roles that can be either gender. Only a man can be assigned to a male role, and only a woman can be assigned to a female role. If five men and six women audition, in how many ways can the six roles be assigned?
Answers
6*5 for the female roles
after they are assigned
7*6 for the either gender
20+30+42 =92 total ways
or
20*30*42= 25200 total ways
There are total 66,000 ways the six roles can be assigned.
What is Multiplication?To multiply means to add a number to itself a particular number of times. Multiplication can be viewed as a process of repeated addition.
Since only a man can play a male role,
We have 5 options for the first male role and 4 options for the second male position (because a guy cannot play both roles).
So there are 5x4 = 20 options for male roles.
Next, consider how many different ways the female positions can be filled. Because only a woman can play a female role,
We have six options for the first female role and five options for the second female position (because a woman cannot play both roles).
So there are 6x5 = 30 possibilities for female roles.
Finally, consider how many different ways the gender-neutral roles can be filled. Because any of the 11 actors can play these parts,
We have 11 options for the first gender-neutral role and 10 options for the second (because one actor cannot play both roles).
So there are 11x10 = 110 possibilities for gender-neutral jobs.
To find the total number of ways the six roles can be assigned,
we multiply the number of ways to fill each set of roles,
Hence,
20 x 30 x 110 = 66,000.

Two college instructors are interested in whether or not there is any variation in the way they grade math exams. They each grade the same set of 10 exams. The first instructor's grades have a variance of 58.9. The second instructor's grades have a variance of 84.8. Test the claim that the first instructor's variance is smaller. (In most colleges, it is desirable for the variances of exam grades to be nearly the same among instructors.) The level of significance is 10%. (Recall: that the larger of the 2 variances needs to be in the numerator as the test is 1-tailed to the right)

Answer:
Since the calculated value of F = 1.4397 is less than the critical value of
F (9,9)= 2.4403 we conclude that the first instructor's variance is smaller and reject H0.
Step-by-step explanation:
1)Formulate the hypothesis that first variance is equal or greater than the second variance
H0: σ₁²≥σ₂² against the claim that the first instructor's variance is smaller
Ha: σ₁²< σ₂²
2) Test Statistic F= s₂²/s₁²
F= 84.8/ 58.9= 1.4397
3)Degrees of Freedom = n1-1= 10-1= 9 and n2 = 10-1= 9
4)Critical value at 10 % significance level= F(9,9)= 2.4403
5)Since the calculated value of F = 1.4397 is less than the critical value of
F (9,9)= 2.4403 we conclude that the first instructor's variance is smaller and reject H0.

Step-by-step explanation:
This is a trapezoid. The area of this trapezoid is [tex]A=\frac{1}{2}(25+33)h[/tex] . 33-25 is 8, so that is the base of the little traingle if we break up the slanted end into a triangle. Now we can use the pythagoreum theorem to find out that the height is 16.125 .
Now the Area equation is [tex]A=\frac{1}{2}(25+33)16.125[/tex]

Tim says 1/8 of this model is shaded. Lucy says 8/8 of this model is shaded.
Answers
Answer:
Step-by-step explanation: Lucy is correct because all of the squares are filled, and therefore instead of 1 square filled, 8 are, this is why lucy is correct :)
Answer:
Lucy is correct.
Step-by-step explanation:
We can see that the ENTIRE model is shaded ( all eight squares).
So Lucy is correct since she stated that 8 out of 8 (8/8) squares are shaded.
8/8 = 1, so whole.
1/8 would mean that only one out of eight squares is shaded, so Tim is NOT coorrect.

Answer:
A
Step-by-step explanation:
we can find out by writing its equation;
9-(-3) / (14-4) = 12 / 10 = 6 / 5
so its equation gonna be y = 6/5x - 7.8
.
now we can grid in the answer choices:
-9 = -6/5 -7.8 so (-1 , -9) is the correct answer
.
First what you can do is find the eq of the line where you need the slope(m) and a point on the line
To find slope (m)
(Y2-y1)/(x2-x1)
(4,-3)=(x1,y1)
(14,9)=(x2,y2)
(9-(-3))/(14-4)
=(9+3)/10
=12/10
m=1.2
Sub this information into the formula
y-y1=m(x-x1)
y-(-3)=1.2(x-4)
y+3= 1.2x -4.8
y=1.2x -7.8
Now sub each point a - d into this to see if they are true
y=1.2x -7.8
a.(-1,-9)
-9=1.2(-1)-7.8
-9=-1.2-7.8
-9=-9
TRUE -POINT IS ON LINE
b.(-2,-8)
-8=1.2(-2)-7.8
-8=-2.3-7.8
-8=-10.1
NOT TRUE -POINT ISNT ON LINE
c.(29,27)
27=1.2(29)-7.8
27=34.8-7.8
27=27
TRUE -POINT IS ON LINE
d.(28,18)
18=1.2(28)-7.8
18=33.6-7.8
18=25.8
NOT TRUE -POINT ISNT ON LINE

The area of the second circle larger than the area of the first circle will be 63.585 square inches.
What is the area of the circle?It is the close curve of an equidistant point drawn from the center. The radius of a circle is the distance between the center and the circumference.
Let r be the diameter of the circle. Then the area of the circle will be
A = (π/4) d² square units
The width of one circle is 12 inches long. The width of a subsequent circle is 25% longer than the measurement of the primary circle.
The diameter of the second circle is given as,
⇒ 1.25 x 12

The area of the first circle is given as,
A₁ = (π/4) (12)²
A₁ = 113.04 square inches
The area of the second circle is given as,
A₂ = (π/4) (15)²
A₂ = 176.625 square inches
The area of the second circle larger the area of the first circler is given as,

When driving in England, Brian drove through several speed cameras. On one drive, Brian left his hotel and after 7 minutes he was 2.5 km away and at that moment was measured going 0.5 kpm (kilometers per minute). Later, 18 minutes after he started driving, he was 14.8 km from the hotel and at that moment was measured going 0.8 kpm.
A. Find the linearization at 7 minutes.
B. Find the linearization at 18 minutes.
C. Compute two approximations for Brian's distance from his hotel at 14 minutes, using the linearizations from parts a and b.
D. Which approximation do you think is better? Why?
Answers
Solution :
The formula for the linearization of a function [tex]$f(x)$[/tex] at a point [tex]$x$[/tex] = a is given as
[tex]$L(x)=f(a)+(x-a)f'(a)$[/tex]
Assuming the time is t and the distance travelled is [tex]$f(t)$[/tex], that makes the speed as [tex]$f'(t)$[/tex].
So substituting them in the linearization formula,
A. At t = 7 minutes
f(7) = 2.5 km
f'(7) = 0.5 kpm
∴ [tex]$L_7(t)=f(7)+(t-7)f'(7)$[/tex]
[tex]$=2.5+(t-7)0.5$[/tex]
[tex]$=2.5+0.5t-3.5$[/tex]
[tex]$=0.5t-1$[/tex]
B. At t = 18 minutes
f(18) = 14.8 km
f'(18) = 0.8 kpm
∴ [tex]$L_{18}(t)=f(18)+(t-18)f'(18)$[/tex]
[tex]$=14.8+(t-18)0.8$[/tex]
[tex]$=14.8+0.8t-14.4$[/tex]
[tex]$=0.8t-0.4$[/tex]
C. Substituting the value of t as 14 in both the linearization to determine the position at 14 minutes, we get
[tex]$L_7(14)=0.5(14)-1.0$[/tex]
= 7 - 1
= 6 km
[tex]$L_{18}(14)=0.8(14)+0.4$[/tex]
= 11.2 + 0.4
= 11.6 km
D. According to the linearization at 7, the distance travelled between the 7 minutes and 14 minutes is = 6 km - 2.5 km
= 3.5 km
And between the 14 minutes and 18 minutes is = 14.8 km - 6 km
= 8.8 km
This is an average speed of 0.5 kpm in the first interval and an average speed of 2.2 kpm.
Now, according to the linearization of 18, the distance travelled between the 7 minutes and the 14 minutes is = 11.6 km - 2.5 km
= 9.1 km
And between 14 minutes and 18 minutes is = 14.8 km - 11.6 km
= 3.2 km
This gives an average speed of 1.3 kpm in the first interval and 0.8 kpm in the second interval.
Therefore, the second approximation is the better one since the average speed are closer to the actual readings in the second linearization.
