Answer:
0.0108 = 1.08% probability that a sophomore non-Chemistry major and then a junior non-Chemistry major are chosen at random.
Step-by-step explanation:
A probability is the number of desired outcomes divided by the number of total outcomes.
Probability that a sophomore non-Chemistry major
Out of 92 students, 9 are non-chemistry major sophomores. So
[tex]P(A) = \frac{9}{92}[/tex]
Then a junior non-Chemistry major are chosen at random.
Now, there are 91 students(1 has been chosen), of which 10 are non-chemistry major juniors. So
[tex]P(B) = \frac{10}{91}[/tex]
What is the probability that a sophomore non-Chemistry major and then a junior non-Chemistry major are chosen at random
[tex]P = P(A)*P(B) = \frac{9}{92}*\frac{10}{91} = \frac{9*10}{92*91} = 0.0108[/tex]
0.0108 = 1.08% probability that a sophomore non-Chemistry major and then a junior non-Chemistry major are chosen at random.
Franklin is purchasing replacement equipment for outdoor recess. Mr. DiCanio put in an order totaling $97.23 to purchase 4 playground balls for $17.25 each, a package of 10 jump ropes for $18.75, and 1 Nerf football. How much did the Nerf football cost?
Answer:
Nerf football cost is $9.48.
Step-by-step explanation:
Total order made by Mr. DiCanio = $97.23
A playground ball cost $17.25 each, so that the cost of 4 playground balls can be determined by;
4 playground balls = $17.25 x 4 = $69.0
A package of 10 jump ropes = $18.75
Cost incurred on the items above = $69.0 + $18.75
= $87.75
Thus,
The cost of 1 Nerf football = $97.23 - $87.75\
= $9.48
Therefore, the cost of Nerf football is $9.48

Answer:
Yes is just like using the slope intercept form
Step-by-step explanation:
Solve the inequality.
x + 23 < 37
Group of answer choices
x < 60
x < 14
x < 37
x < 23
Answer:
x = 14
x + 23 < 37 ( move constant to right-hand side and change its sign)
x<37-23 ( subtract numbers)
x < 14

The diameter of a monster truck tire is 6 feet. If the truck tire makes 12 revolutions, how far did the truck travel?
Answer:
About 207 inches
Step-by-step explanation:
The circumference of a circle is given by the formula ...
C = πd . . . . . where d represents the diameter
The circumference of the tire is the distance the truck will move when the tire makes one revolution. That distance is ...
C ≈ 3.1416×(66 in) ≈ 207.35
The truck will travel about 207 inches for each revolution of the tire.

What political changes occurred in the years shortly before World War I?
If sin 0º = 0, then csc 0°=
(check image)
Answer:
Step-by-step explanation:
sin(0) = 0/2
sin(30) = 1/2
sin(45) = [tex]\sqrt{2}[/tex]/2
sin(60) = [tex]\sqrt{3}[/tex]/2
sin(90) = [tex]\sqrt{4}[/tex]/2
cos(90) = 0/2
cos(60) = 1/2
cos(45) = [tex]\sqrt{2}[/tex]/2
cos(30) = [tex]\sqrt{3}[/tex]/2
cos(0) = [tex]\sqrt{4}[/tex]/2
notice that sin and cos repeat, but in reverse

Answer:
x = 10
Step-by-step explanation:
3x - 5 = 2x + 5
3x - 5 + 5 = 2x + 5 + 5
3x = 2x + 10
3x - 2x = 2x - 2x + 10
1x = 10
x = 10
Answer:

Brenda and Sam are going to stay at the hotel for one night. It costs a total of £84 to stay at the hotel for one night. Brenda pays a deposit of £20 towards the total cost. Brenda says to Sam, 'We will share the total cost equally.' How much does each person have left to pay?
Answer:
£32 and £32
Step-by-step explanation:
The computation of the amount that should be left and equally distributed is shown below:
The cost of hotel for one night is £84
Brenda has make a deposit of £20
So, the remaining amount left is
= £84 - £20
= £64
Now this amount should be equally distributed between them i.e. £32 and £32
what is the surface area ?
A. 78
B. 57
C. 50
D. 72
I gave Brainlist you ever answer first
Answer:
A. 78
Step-by-step explanation:
7 x 4 is the bottom and the bottom is the same as the top so I got 28 x 2 which is 56. 4 x 1 is one side. The other side is the same so I got 4 x 2 which is 8. 1 x 7 is the front and back. I got 7 x 2 is 14. i wrote 56 + 14 + 8 and got 78
hope this helps :)

b⁶
Step-by-step explanation:
The question tells you how to work it: use the relations you studied.
Here, you have the power of an expression with an exponent. The exponents multiply.
[tex]\text{Rule: }(a^b)^c=a^{bc}\\\\\text{Appication: }(b^3)^2=b^{3\cdot2}=\boxed{b^6}[/tex]
_____
Additional comment
A coefficient is used to indicate repeated addition: 3x = x + x + x.
An exponent is used to indicate repeated multiplication: x³ = x·x·x.
This is still true when the exponent is applied to an expression with an exponent:
(b³)² = (b³)(b³) . . . . the factor b³ is repeated 2 times as indicated by the exponent 2
Of course, each of these indicates repeated multiplication, so we really have ...
(b³)(b³) = (b·b·b)·(b·b·b) = b·b·b·b·b·b
And this can be simplified using an exponent to show the repeated multiplication:
= b⁶
Then, by going the long way around, we arrive at ...
(b³)² = b⁶

Answer:
Step-by-step explanation:
Those consecutive angles must sum to 180 degrees.
7x+9+7y-4=180
7x+7y+5=180
7x+7y=175
x+y=25
x=25-y
We also have
11x-1+2y+5=180
11x+2y+4=180
11x+2y=176, using x=25-y that we found above makes this
11(25-y)+2y=176
275-11y+2y=176
-9y+275=176
-9y=-99
y=11, and since x=25-y
x=25-11
x=14
Finally
z+7x+9=180
z+7x=171
z=171-7x, we found that x=14 earlier so
z=171-7(14)
z=171-98
z=73
So the three values are
x=14, y=11, and z=73 degrees.

Select the graph that correctly represents ƒ(x) = –2(x + 4)2 – 1.Find the equation of the parabola with its focus at (3,4) and its directrix y = 0.
Answer:
Equation of parabola: 8*(y - 2) = (x - 3)^2
or
y = (1/8)*(x - 3)^2 + 2
Step-by-step explanation:
focus at (3,4) and its directrix y = 0.
Focus equation: (h, k + c) = (3, 4)
Directrix equation y = k - c = 0
so h = 3, k + c = 4, k - c = 0
Solve the system : k + c = 4 and k - c = 0
add the equations together: k + c + k - c = 4 + 0
2k = 4
k = 2
so k + c = 4, 2 + c = 4, c = 2
4c (y - k) = (x - h)^2
4*2 *(y - 2) = (x - 3)^2
8*(y - 2) = (x - 3)^2
