Step-by-step explanation:
the probability of randomly selecting a four-person committee consisting entirely of canadians from a pool of 11 americans and 18 canadian
Answer:
[tex]Probability =0.1744[/tex]
Step-by-step explanation:
Given
Total
[tex]American = 11[/tex]
[tex]Canadian = 18[/tex]
Selection
[tex]American = 0[/tex]
[tex]Canadian = 4[/tex]
Required
Determine the probability of selecting a 4 committee member that are Canadian.
First, we calculate total possible selection.
[tex]Total = American + Canadian[/tex]
[tex]Total = 11 + 18[/tex]
[tex]Total = 27[/tex]
Number of ways to select 4 from 27 is:
[tex]^{27}C_4 = \frac{27!}{(27-4)!4!}[/tex]
[tex]^{27}C_4 = \frac{27!}{23!4!}[/tex]
[tex]^{27}C_4 = \frac{27*26*25*24*23!}{23!4!}[/tex]
[tex]^{27}C_4 = \frac{27*26*25*24}{4!}[/tex]
[tex]^{27}C_4 = \frac{27*26*25*24}{4*3*2*1}[/tex]
[tex]^{27}C_4 = \frac{421200}{24}[/tex]
[tex]^{27}C_4 = 17550[/tex]
Next, we calculate ways of selecting 4 Canadians from 18 is:
[tex]^{18}C_4 = \frac{18!}{(18-4)!4!}[/tex]
[tex]^{18}C_4 = \frac{18!}{14!4!}[/tex]
[tex]^{18}C_4 = \frac{18*17*16*15*14!}{14!4!}[/tex]
[tex]^{18}C_4 = \frac{18*17*16*15}{4!}[/tex]
[tex]^{18}C_4 = \frac{18*17*16*15}{4*3*2*1}[/tex]
[tex]^{18}C_4 = \frac{73440}{24}[/tex]
[tex]^{18}C_4 = 3060[/tex]
The required probability is:
[tex]Probability =\frac{3060}{17550}[/tex]
[tex]Probability =0.1744[/tex]

Melanie earns $7 per hour when she
baby-sits. An equation for this relation
is w = 7h, where h represents the
number of hours and w represents
Melanie's wage in dollars.
a) Use the equation to create a table
of values.
b) In one week, Melanie earned $105.
How many hours did she baby-sit?
c) In one month, Melanie baby-sat for
24 h. How much did she earn
from baby-sitting in that month
Answer:
A) We know that she make $7 per hour, with this we can make a table:
1hr | $7
2hr | $14
3hr | $21
etc...
B) If in one week she earns $105 and 1w = 7h (1hr = $7) holds true, that means that we have to divide 105 by 7 which gives us 15hrs
C) If she baby-sat for 24hrs, we just have to multiply that by 7 and we get $168
Hope that helped!

Solve for the roots in simplest form using the quadratic formula:
4x^2 -28x= -53
Answer:
x = (28 +- root -64) / (8)
Step-by-step explanation:
4x^2 -28x= -53 = 0
x = [-(-28)+- root (-28)^2 - 4 * 4 * 53] / 2 *4
x = (28 +- root 784 - 848) / (8)
x = (28 +- root -64) / (8)

250 g
D = 20 g
Cup

a = 10g
Let T = the total mass of a randomly selected cup filled with liquid from this machine.
Find the mean of T.

Stuck? Watch a video or use a hint.
Report a problem
Answer:400
Step-by-step explanation:
The mean of T is the expected weight of a selected cup filled with liquid
The mean of T is 400
The data on the table is given as:
Mean Standard Deviation
Liquid 250g 20g
Cup 150g 10g
Represent Liquid with L, and cup with C
To calculate the mean of T, we make use of the following formula for expected value
E(L + C)
Since L and C are independent random variables, then
[tex]E(L + C) = E(L) + E(C)[/tex]
Where E(L) and E(C) are the mean values of liquids and cups.
The equation becomes
[tex]E(L + C) = 250g + 150g[/tex]
[tex]E(L + C) = 400g[/tex]
Hence, the mean of T is 400

Doug drew two identical triangles. He wants to prove the converse of the Pythagorean Theorem by using both triangles. The first triangle has side lengths of 12 cm, 16 cm, and 20 cm, such that 122 + 162 = 202. Using the converse of the Pythagorean Theorem, enter the length of the side opposite the 90° angle of the second triangle.______cm
Answer:
Answer is explained in the explanation section
Step-by-step explanation:
Solution:
Converse of the pythagorean theorem helps us to check whether a triangle is a right triangle or not. Converse of the pythagorean theorem is simply the opposite of the pythagoren theorem. Pythagorean theorem states that, if triangle is right triangle, then [tex]a^{2} + b^{2} = c^{2}[/tex]. On the other hand, Converse of the Pythagorean theorem states that, if [tex]a^{2} + b^{2} = c^{2}[/tex], then triangle is a right triangle.
Pythagorean theorem = [tex]c^{2} = a^{2} + b^{2}[/tex]
Converse of the pythagorean theorem = [tex]a^{2} + b^{2} ? c^{2}[/tex]
First of all let's check the first triangle is right triangle or not.
a = 12
b= 16
c= 20
So,
[tex]a^{2} + b^{2} = c^{2}[/tex].
144 + 256 = 400
400 = 400
Yes, 1st triangle is no doubt a right triangle. On the other hand, we are given that 2nd triangle = right triangle as we are given the 90 degree angle already. Here, we know that triangle is a right triangle
hence, [tex]a^{2} + b^{2} = c^{2}[/tex]. will surely be there.
Now, we have find out the side opposite to the 90 degrees angle, which is c.
we also know that, right triangles sides follow the pattern of 3x,4x and 5x
Since, c is the longest side.
Hence, c= 5x
how do you solve 9 tenths minus 13 fiftenths
Answer:
0.04
Step-by-step explanation:
1. 9/10 = 0.9 and 13/15 = 0.86
2. Subtract 0.9 and 0.86
3. You should end up with 0.04
Remember when a number goes like 0.86666666666 to use 0.86 or if it has 0.86666666667 to use 0.87 because you would be simplifying it.

Monica had a savings account that paid her an interest rate of 4%. After she had this account for 12 years, she had received $192 in interest. How much money had she put into the account at the beginning of the 12 years?
Answer:
Money she put in her account = $400
Step-by-step explanation:
As, to find the interest the formula is PTR/100 = I
Where P = Principcal
And T = time (in years)
And R = rate
And I = interest
So here p is not present we need to find it
R = 4%
And T = 12 years
And I = $192
= p x 4 x 12 /100 = 192
P x 4 x 12 = 19200
P x 48 = 19200
P = 19200/48
P = 400
So Principcal = $400
