find the mean, variance, and standard deviation of the binomial distribution with the given values of n and p. n= 60, p= 0.3
The mean is just the multiplication of [tex]n[/tex] and [tex]p[/tex] so [tex]60 * 0.3[/tex] = [tex]18[/tex]
Variance is [tex](1 - p) * n * p[/tex] so [tex]0.7 * 60 * 0.3 = 12.6[/tex]
So the variance is [tex]12.6[/tex]
The standard deviation is just the root of the variance so: [tex]\sqrt{12.6}[/tex] = [tex]3.55[/tex] rounded to the nearest hundredth. :D

Step-by-step explanation:
Morgan has $60 to spend on clothes. he wants to buy a pair of jeans for $25 and spend the rest on t shirts each t shirt costs $5 which inequality represents the number of t shirts he can purchase
a x ≥ 7
b x ≤ 16
c x ≤ 7
d x ≥ 16
(the signs are less or equal to and more or equal to)
Answer:
C
Step-by-step explanation:
Morgan has $60. That is his spending limit.
He buys a pair of jeans for $25.
Each T-shirt is $5
We don't know how many t-shirts he can buy, so we can represent it with a variable, x
so,
[tex]25 + 5x \leq 60\\5x \leq 60 - 25\\5x \leq 35\\x \leq \frac{35}{5} \\x\leq 7[/tex]

75 – 3.5y – 4y = 4y + 6
Answer:
y=6
Step-by-step explanation:
75-3.5y-4y=4y+6
combine like terms)
75+(-3.5y-4y)=4y+6
75-7.5y=4y+6
add 4y to each side to combine the terms) 75+(-7.5y-4y)=6
75-11.5y=6
subtract 75 from each side to isolate the variable) -11.5y=-69
divide by -11.5 to isolate the variable) -11.5y/-11.5=-69/-11.5
y=6

Alan just got a Fall job. The equation P = 12.50h represents the salary P (in dollars) he will earn when he works h hours. How much is he earning per hour?
Given:
Alan salary P (in dollars) when he works h hours is represented by the equation
[tex]P=12.50h[/tex]
To find:
The earning per hour.
Solution:
We have,
[tex]P=12.50h[/tex]
Here, P is total salary and h is number of hours he works.
[tex]\text{Earning per hour}= \dfrac{\text{Total salary}}{\text{Number of hours}}[/tex]
[tex]\text{Earning per hour}= \dfrac{12.50h}{h}[/tex]
[tex]\text{Earning per hour}=12.50[/tex]
Therefore, the earning per hour is $12.50.

Is 45m, 36m, 27m a right triangle
Answer:
it is the right triangle
Step-by-step explanation:
A set of three integers that can be the length of the sides of a right triangles
Answer:
Yes
Step-by-step explanation:
This is what I think:
This is because the hypotenuse of the triangle is 45m.
27 ^2 + 36 ^2 = 2025
2025 SQAURE ROOT IS 45.
So the square root of the two other measurements squared must be equal to the hypotenuse.

Which inequality best represents that ice cream at −2°C is cooler than ice cream at 3°C? Group of answer choices −3°C > 2°C −3°C < 2°C 3°C > −2°C 3°C < −2°C
Answer:
3°C > - 2°C
Step-by-step explanation:
Ice cream 1 = - 2°C
Ice cream 2 = 3°C
Lower temperatures are colder (cooler) than higher temperature values.
Hence, ice cream at - 2°C is cooler than ice cream at 3°C.
Hence, a temperature of 3°C is higher (greater) than - 2°C. Hence - 2°C is cooler (colder) than 3°C
Hence,
3°C > - 2°C

60 + 4 + 8x = 8 + 16x add like terms
8x + 64 = 16x + 8
64 - 8 = 16x - 8x
56 = 8x divide both sides by 8

1. 0.008
2. Square root of 64 is 8 and cube root of 64 is 4. The difference is 4.
3. Area=100 sq.cm. The side is 10 cm. so the perimeter is 4 x Side= 4x10=40 cm.
4. the two square roots of 25 are 5 and 5. Cuz 5 and 5 gives 25.

What is congruent geometry?In geometry, two figures are congruent if they have the same shape and size, and all their corresponding parts (sides, angles, and vertices) are congruent. Congruent figures can be moved, rotated, or reflected without changing their shape or size.
Here,
To prove that ΔPQS = ΔRQS, we need to show that two pairs of corresponding sides and one pair of corresponding angles are congruent.
Looking at the diagram, we can see that:
PQ = RQ (corresponding sides)
PQ = RQ (common side)
∠PQS = ∠RQS (common angle)
To prove that the two triangles are congruent, we can use the SAS (Side-Angle-Side) postulate, which states that if two pairs of corresponding sides and one pair of corresponding angles are congruent in two triangles, then the triangles are congruent.
Therefore, the answer is (A) SAS.

The figure below shows the letter Z and four of its transformed images-A, B, C, and D: A coordinate plane is shown. The letter Z has endpoints at negative 6 comma 3, negative 6 comma 1, negative 4 comma 1 and negative 4 comma 3 and has a diagonal line that goes from top right to bottom left in between. A is a shape that has endpoints at 4 comma 3, 4 comma 1, 6 comma 3 and 6 comma 1 and has a diagonal line that goes from top left to bottom right. B has endpoints at negative 6 comma negative 1, negative 6 comma negative 3, negative 4 comma negative 1 and negative 4 comma negative 3 and has a diagonal line that goes from top right to bottom left. C has endpoints at negative 3 comma negative 1, negative 3 comma negative 3, negative 1 comma negative 1, negative 1 comma negative 3, and has endpoints that go from top left to bottom right. D has endpoints at 2 comma negative 1, 2 comma negative 3, 4 comma negative 1, and 4 comma negative 3 and has a diagonal that goes from top right to bottom left. Which of the four images was formed by a reflection of the letter Z? (5 points) A B C D
Answer:its c
Step-by-step explanation:
Answer:
The answer is A
Step-by-step explanation:
The answer is A because a reflection would be Reflected so its on the right side of the graph and the Z is facing the other way as if it were a literal reflection which it is.
Hope my awkward way of explaining this helps you on your test since i just passed mine and it said A was correct.
Colin gets £xx wages each week. After he pays his tax of £tt, he then pays his rent of £250. He shares what's left between himself and his wife. How much do they each get?

The amount left from x after paying t and 250 is ...
x -t -250
If this is split into two equal parts, each share is ...
share = (x -t -250)/2
11. A line passes through the point (2, 3) and has a slope of 2.
11a. What are the steps you take to find the y-intercept?
11b. What is the equation of the line?
Answer:
11. y=2x-1
11a. you subtract 2 from the y and 1 from the x and draw your points accordingly to go down or you add 2 to the y and add 1 to the x to go up and plot the points accordingly or you could just draw a graph like i did if you dont wanna do it by math lol. :)

Mr. Gomez needs to rent a moving truck. Company "A" charges $75 plus a $50 a day and Company "B" charges $105 plus $35 a day. Write an equation that can tell after how many days would the price be the same.
Answer: 75+50x= 105+35x , required equation.
Step-by-step explanation:
Let x = Number of days
Given: Company "A" charges $75 plus a $50 a day.
Total charge = 75+50x
Company "B" charges $105 plus $35 a day.
Total charge = 105+35x
When both are same , equation becomes
75+50x= 105+35x
So, Required equation: 75+50x= 105+35x
