How to calculate the average:
In order to find the average, you need to add a group of numbers and then divide by how many numbers there is.
(((For example: 2, 3, 3, 5, 7, 10 -- That equals 30. Then to find the average, you need to divide (30) by how many numbers there is (6). 30/6=5. The average of this is 5)))
This set of numbers is 63, 53, 20, 10. The current average is 36.5.
Adding 9 to that number makes it equal 155. To find the average, we now have to divide 155 by 5(because thats how many numbers there is.
155/5=31

Pranv and Paul improve the yard by planting grass sod and shrubs they bought their supplies from the same store craft spent $90 on 10 feet of grass and grass sod and five shrubs paul spent $50 on 5 feet of grass sod and three shrubs find the cost of one foot of grass sod and a cost of one shrub
Answers
Answer:
The cost of one foot of grass sod is $9 and the cost of one shrub is $18.
Step-by-step explanation:
Since Pranv and Paul both bought their supplies from the same store, we can assume that they paid the same price per foot of grass sod and per shrub. From the information given, we know that Pranv spent $90 on 10 feet of grass sod and 5 shrubs, which means that he paid 90/10 = $9 per foot of grass sod and 90/5 = $18 per shrub. We also know that Paul spent $50 on 5 feet of grass sod and 3 shrubs, which means that he paid 50/5 = $10 per foot of grass sod and 50/3 = $16.67 per shrub. Since both Pranv and Paul paid the same price per foot of grass sod and per shrub, the cost of one foot of grass sod is $9 and the cost of one shrub is $18.

Answers
Answer:
17%
Step-by-step explanation:
Let us say there are 200 people on the JV swim team. That would mean that 110 people do not wear glasses.
Of these 110 people, 30% are in 10th grade. Therefore, 33 people are in 10th grade and do not wear glasses.
This is 33 people ÷ 200 total = 16.5% ≈ 17%
Therefore, there is a 17% probability that a randomly chosen member of the jv swim team does not wear glasses and is in the 10th grade
[NOTE] You could also just do 55% × 30% = .55 × .30 = .165 ≈ .17 ⇒ 17%

At a basketball game, a team made 59 successful shots. They were a combination of 1- and 2-point shots. The team scored 99 points in all. Write and solve a system of equations to find the number of each type of shot.
Answers
Answer:
Step-by-step explanation:
Let x be the number of 1-point shots and y be the number of 2-point shots. We know that the total number of shots is 59 and the total number of points is 99. We can write these two equations as follows:
x + y = 59
1x + 2y = 99
To solve this system of equations, we can use substitution. We can solve the first equation for y and substitute the result into the second equation:
y = 59 - x
1x + 2(59 - x) = 99
1x + 118 - 2x = 99
-x = -19
x = 19
Now that we know the value of x, we can substitute it into the first equation to find the value of y:
y = 59 - 19 = 40
Therefore, the team made 19 1-point shots and 40 2-point shots.
find the curvature at the point (2, 8, −1). x = 2t, y = 8t3/2, z = −t2
Answers
The curvature at the point (2, 8, −1). x = 2t, y = 8t^3/2, z = −t^2 is 0.039
In this question we need to find the curvature of r(t) = <2t, 8t^3/2, -t^2> at the point (2, 8, -1).
The derivative of r(t) with respect to t is:
r'(t) = <2, 12t^1/2, -2t>
The point (2, 8, -1) corresponds to t = 1,
and r′(1) = <2, 12(1)^1/2, -2(1)>
r'(1) = <2, 12, -2>
|r'(1)| = √(2^2 + 12^2 + (-2)^2)
|r'(1)| = √(4 + 144 + 4)
|r'(1)| = √(152)
|r'(1)| = 12.32
Now, r''(t) = <2, 6t^-1/2, -2>
and r′'(1) = <0, 6, -2>
r′(1) × r′′(1) = <0, 72, 4>
|r′(1) × r′′(1) |
= √(0^2 + 72^2 + 4^2)
=72.11
So, the curvature of r(t) would be,
κ(1) = |r′(1) × r′′(1)| ÷ |r′(1)|^3
k(1) = 72.11 / 12.32³
k(1) =0.039

The cash price of a television is Rs 65 000. The hire purchase price is a deposit of Rs 20 000 and 18 % simple interest on the outstanding balance, to be paid in 2 1/2 years . find the difference between the cash price and the hire purchase price.
Answers
Answer:
To find the difference between the cash price and the hire purchase price, we need to calculate the total hire purchase price.
First, we need to find the outstanding balance after the deposit is paid. We can do this by subtracting the deposit from the cash price:
outstanding balance = cash price - deposit
= Rs 65,000 - Rs 20,000
= Rs 45,000
Next, we need to calculate the total interest to be paid over the 2 1/2 year period. We can do this using the following formula:
total interest = outstanding balance * interest rate * time period
= Rs 45,000 * 18% * 2 1/2 years
= Rs 20,250
Finally, we can add the outstanding balance and the total interest to find the total hire purchase price:
total hire purchase price = outstanding balance + total interest
= Rs 45,000 + Rs 20,250
= Rs 65,250
The difference between the cash price and the hire purchase price is the difference between the total hire purchase price and the cash price. So we can calculate this as follows:
difference = total hire purchase price - cash price
= Rs 65,250 - Rs 65,000
= Rs 250
Therefore, the difference between the cash price and the hire purchase price is Rs 250.
I hope this helps!
= 20 000 + 1.18(65 000 - 20 000)
= 20 000 + 1.18(45 000)
= 20 000 + 53 100
= 73 100
73 100 - 65 000
= 8 100
Therefore, you will spend RS 8 100 more if you buy Hire Purchase Price than the Cash Price of Television.

a box contains 4 blue, 5 white, 6 red, and 7 green marbles. five marbles are chosen at random without replacement. what is the probability that every color will be represented in the sample of 5?
Answers
The probability that every color will be represented in the sample of 5 is 35/7776.
Describe the event without replacement?Each person in a population may only be chosen once when sampling is performed without replacement. In this instance, the outcome of the first pick has an impact on the probabilities again for second pick. It is decided whether or not the events are independent.For the stated question, box contains-
4 blue, 5 white, 6 red, and 7 green marbles.Total marbles = 22probability = favourable outcome/ total outcome
5 marbles are selected with out replacement.
Thus,
Probability of getting all color will occur is-
P(all color) = (4C2)*(5C1)*(6C1)*(7C1) + (4C1)*(5C2)*(6C1)*(7C1) + (4C1)*(5C1)*(6C2)*(7C1) + (4C1)*(5C1)*(6C1)*(7C2) / (10C5)⁴
P(all color) = 6*5*6*7 + 4*10*6*7 + 4*5*15*7 + 4*5*6*21 / 36⁴
P(all color) = 1260 + 1680 + 2100 + 2520 / 1679616
P(all color) = 7560 / 1679616
P(all color) = 35/7776
