there are 10 boys and 20 girls in a class.
the class has a test.
the mean mark for the class is 60.
the mean mark for the girls is 54.
work out the mean mark for the boys.

Answers

Step-by-step explanation:

There are 10 + 20 = 30 total students in the class.

Total marks for the class = 60 * 30 = 1800.

Total marks for the girls = 54 * 20 = 1080.

=> Total marks for the boys = 1800 - 1080 = 720.

Mean mark for the boys = 720 / 10 = 72.

A dog walker service offers a daily service and a weekly service in the winter the ratio of daily customers to weekly customers was one to five however in the spring more customers moved to the daily service because of the nicer weather after the weather changed the ratio was 4:2 if there were 1:5weekly customers in the winter then how many daily customers were there in the spring

Answers

Answer:

Daily customers were there in the spring = 100 customers

Step-by-step explanation:

In winter :

Daily customers to weekly customers = 1:5

In spring

Daily customers to weekly customers = 4:2

And total weekly customer in winter = 125

Find:

Daily customers were there in the spring

Computation:

Total customer in winter = 125[6/5]

Total customer in winter = 150

Daily customers were there in the spring = 150 [4/6]

Daily customers were there in the spring = 100 customers

A computers random number generator produces random integers from 1 - 50. What is the probability that the first three integers generated for single digit numbers

Answers

Answer:

9/50

Step-by-step explanation:

There are nine single digit numbers from integers 1-50 so in order to calculate the probability of getting 3 random numbers from 1-50 to be single digits:

Probability = number of favorable outcomes /total number of outcomes

Therefore Probability of getting 3 single digits randomly from 1-50 = 9/50

What is the sum of the one hundredth of 25, one tenth of thirty and one thousandth of 60?

Answers

Answer:

331/100 or 3 31/100

Step-by-step explanation:

We have;

One - hundredth of 25 = 1/100 × 25 = 1/4

One-tenth of 30 = 1/10 × 30= 30/10 =3

One-thousandth of 60= 1/1000 × 60= 60/1000= 3/50

So we have:

1/4 + 3 + 3/50 = 331/100 or 3 31/100

A triangle on a coordinate plane is translated according to the rule T-3, s(x, y). Which is another way to write this rule?
O K.y) - «-3, y + 5)
O (.y)- -3.y- 5)
O (x.y)- (x+ 3, y-5)
O «.y) - («+3, y + 5)

Answers

Answer:

The rule indicates that the original (x, y) coordinates will be moved to the left by 3 units and up by 5 units.

Thus,

(x, y) ⇒ (x – 3, y + 5)

Step-by-step explanation:

Given the rule T–3, 5(x, y)

The rule indicates that the original (x, y) coordinates will be moved to the left by 3 units and up by 5 units.

It means we need to subtract 3 units from the x-coordinate and add 5 units in the y-coordinate.

Thus, if a triangle on a coordinate plane is translated according to the

rule T-3, s(x, y), then another way to write this rule will be:

(x, y) ⇒ (x – 3, y + 5)

How many coats should Clothes-4-You expect to sell when the average temperature is 80°F?

What is the predicted temperature when 125 coats are sold?

Answers

Answer:

its 3 and 60 on edg

Step-by-step explanation:

Answer:

26 coats; -23°F temperature

Step-by-step explanation:

For x = 80, we have:

y = - 0.96*80 + 103 = 26.2 ≈ 26 coats expected to be sold

Predicted temperature when 125 coats are sold:

125 = - 0.96x + 103- 0.96x = 22x = 22/-0.96x = -22.9 ≈ -23°F
