What is the probability a server will refuse to serve alcoholic beverages to exactly 2 minors if he randomly checks the IDs of 5 of the 9 students in the establishment, and 4 of the 9 students are minors?
Answer:
10/21
Step-by-step explanation:
Probability = Expected outcome/total outcome
If he randomly checks the IDs of 5 of the 9 students in the establishment, the total outcome will be expressed as:
9C5 = 9!/4!5!
9C5 = 9×8×7×6×5!/5!×24
9C5 = 9×8×7×6/24
9C5 = 126
Total outcome = 126
For the expected
First we know that 4out of 9 students are minor, and we want to know the probability that exactly 2 are minor, this can be done in 4C2 ways
4C2 = 4!/2!2!
4C2 = 4×3×2/4
4C2 = 6
Also since 4 out of 9 are minor, then 5 are not minor and if out of every 5, exactly two are minor, then 3 are not.
Those not minor can be expressed in 5C3 ways
5C3 = 5!/2!3!
5C3 = 5×4×3!/2×3!
5C3 = 20/2
5C3 = 10
Total expected outcome = 4C2 × 5C3
Total expected outcome= 6×10 = 60
Hence, the probability a server will refuse to serve alcoholic beverages to exactly 2 minors will be;
= 60/126
= 30/63
= 10/21
Lavonda took out a $7,500 loan with an APR of 3.875\% and agreed to pay it back monthly over 6 years
What is her monthly payment?
How much will she pay back in total?
What is the finance charge?
Answer:
Step-by-step explanation:
Given data
principal=$7500
rate= 3.875%= 0.03875
time =6years
The expression for the final amount for a simple interest is
A=p(1+rt)
A=7500(1+0.03875*6)
A=7500(1+0.2325)
A=7500(1.2325)
A=9243.75
$19243.75
1. What is her monthly payment?
given that it is spread over 6 years
there are 12*6 months= 72months
monthly pay=9243.75/72= $128.38
2. How much will she pay back in total?
=$19243.75
3. What is the finance charge?
the finance charge is the interest which is
$19243.75-$7500=$11743.75

Answer:
1/4
Step-by-step explanation:
rewrite the response: 1/3 times 3/4 (multiply by the reciprocal of the second #)
then multiply both numerators and denominators: 3/12 is what u get from mult.
then u simplify the fraction: 1/4
Answer:
First, rewrite the problem as a multiplication problem. Multiply 1/3 by the reciprocal of 4/3, which is 3/4. Then multiply to get 3/12. Simplifying gives the answer of 1/4.

Put the following equation of a line into slope-intercept form
2x - 2y = 6
Answer:
Y=-2x+3
Step-by-step explanation:
2x-2y=6
2y=-2×+6
y=-2×+6/2
y=-2x+3
The equation of a line into slope-intercept form is y = x - 3
The standard form of an equation in slope-intercept form is expressed using the equation y = mx + b
m is the slope of the line
b is the y-intecept
Given the equation 2x - 2y = 6
Divide through by 2
x - y = 3
-y = -x + 3
Multiply through by -1
-(-y) = -(-x) + (-3)
y = x - 3
Hence the equation of a line into slope-intercept form is y = x - 3

given cosx = 60/61, find sin2x
Recall that for all x,
cos²(x) + sin²(x) = 1
So we have
sin(x) = ± √(1 - (60/61)²) = ± 11/61
Recall the double angle identity,
sin(2x) = 2 sin(x) cos(x)
From here, we get
sin(2x) = 2 (± 11/61) (60/61) = ± 1320/3721
In case you meant to ask about sin²(x), we get
sin²(x) = 1 - cos²(x) = 121/3721

The population standard deviation for the heights of dogs, in inches, in a city is 7.5 inches. If we want to be 90% confident that the sample mean is within 2 inches of the true population mean, what is the minimum sample size that can be taken
Answer: 39
Step-by-step explanation:
Formula of sample size :
[tex]n=(\dfrac{z^c\times\sigma}{E})^2[/tex] , where [tex]z^c[/tex] = critical z-value for confidence level , [tex]\sigma[/tex] = population standard deviation , E = margin of error.
[tex]\Rightarrow\ n=(\dfrac{1.645\times7.5}{2})^2\\\\\Rightarrow\ n=(6.16875)^2=38.05347\approx39[/tex]
Hence, the minimum sample size that can be taken = 39

I think it is 47 divided by 7, but the answer is very long and unrealistic, so it may be wrong. You could try rounding it to the nearest hundredth, which would be 6.71 pounds. Maybe wait for another answer, because this could be wrong!!
solve for the variable 4a-9=7a+12
Thanks!!
Answer:
a = - 7
Step-by-step explanation:
Given
4a - 9 = 7a + 12 ( subtract 7a from both sides )
- 3a - 9 = 12 ( add 9 to both sides )
- 3a = 21 ( divide both sides by - 3 )
a = - 7

triangle. By how many degrees was he off when he attached the triangle to the stick?

His flag ended up with base angles of 86 and 62. so the stick was 12 out of alignment from the correct position (both angles
74°).
His flag ended up with base angles of 86° and 52° so the stick was 22° out of alignment from the correct position (both angles

His flag ended up with base angles of 289 and 629, so the stick was 34 out of alignment from the correct position (both angles
62").

Answer:
a. His flag ended up with base angles of 86° and 62°. so the stick was 12° out of alignment from the correct position (both angles
74°).
Step-by-step explanation:
First, let's calculate the measures of the base of the angles Neko ended up with.
The measure of the angle adjacent to the exterior angle = 180° - 118° = 62°
The measure of the other base = 180° - (62° + 32°) = 180° - 94° = 86°
So, Neko ended up with 86° and 62°.
To make a flag that is in the form of an isosceles ∆, it means the measure of the two bases most be equal to each other.
Since he measures the tip of the flag to be 32°, the measure of the remaining two equal bases ought to be (180 - 32)/2 = 148/2 = 74° each.
The difference between 74° and what he ended up with = 86 - 74 = 12°.
74 - 62 = 12°.
Therefore, the stick was 12° out of alignment.

How to Solve X-3/8= 7/16
Answer:
x=13/16
Step-by-step explanation:
The question is asking us to isolate the variable x. This means that we need to add -3/8 to both sides of the equation. Because the denominators of the fractions 3/8 and 7/16 are not the same, we need to find a common denominator, which is 16. (So we change 3/8 to 6/16 because the two fractions are equal). Now that we have the fractions 6/16 and 7/16 we can add the two to get x=13/16

over a long time, cable from acme cable co has a mean strength of 37.5 ksi with a known population standard deviation of 1 ksi. find the probability that a random piece of th ecable has a strength x lower than 36.0 ksi
Answer:
The value is
[tex]P(X < 36) = 0.066807[/tex]
Step-by-step explanation:
From the question we are told that
The mean is [tex]\mu = 37.5 \ ksi[/tex]
The standard deviation is [tex]\sigma = 1 \ ksi[/tex]
Generally the probability that a random piece of the cable has a strength x lower than 36.0 ksi is mathematically represented as
[tex]P(X < 36) = P(\frac{X - \mu}{ \sigma } < \frac{ 36 - 37.5}{1} )[/tex]
[tex]\frac{X -\mu}{\sigma } = Z (The \ standardized \ value\ of \ X )[/tex]
[tex]P(X < 36) = P(Z < -1.5 )[/tex]
From the z table the probability of [tex](Z < -1.5)[/tex] is
[tex]P(Z < -1.5) = 0.066807[/tex]
So
[tex]P(X < 36) = 0.066807[/tex]
