find the surface area 3 No files

Answer:

6. (27÷3) × v = 45

9 × v = 45

v = 45/9 = 5

F. 5

5. (2×19) + 3 = j

38 + 3 = j

j = 41

C. 41

4. 7 + t = 4 + 6 + 3

t = 13 - 7

t = 6

J. 7+t = 4+6+3

t = 6 tickets

Answer:

First question=5 : Second question= 41 : Third question= J

Step-by-step explanation:

27 divided by 3 is 9, so planting one violet takes 9 minutes, if they spend 45 minutes planting them you divide 45 by 9 and get 5.

:)

Ada ate 19, rob ate double Adas amount, so 19x2 to get Robs total of 38, then Jane ate 3 more than rob, so 38+3=41

6 is the 13 tickets she needs -7 that she has already.

Answer:

±6

Step-by-step explanation:

Given the mathematical expression;

√36 < √42 < √49

But, √36 = 6 * 6 = 6²

√49 = 7 * 7 = 7²

Simplifying further, we would substitute the new values respectively;

±[6] < √42 < ±[7]

Therefore, evaluating √36 is equal to ±6.

Answer:

-1.5

Step-by-step explanation:

The Z - score of a person who scored 240 on the exam will be - 1.5.

What is Standard deviation?

Standard deviation is the measure of dispersed the data is in relation to the mean. Low standard deviation means data are clustered around the mean, and high standard deviation indicates data are more spread out.

Given that;

On a standardized exam,

The mean of scores = 300

Standard deviation = 40

Score on the exam = 240

Now,

Since, The Z - score is defined as;

Z - score = (X - μ) / σ

Where, μ is mean of scores and σ is Standard deviation.

Substitute all the values , we get;

Z - score = (X - μ) / σ

Z - score = (240 - 300) / 40

Z - score = - 60 / 40

Z - score = - 1.5

Therefore,

The Z - score of a person who scored 240 on the exam will be - 1.5.

Step-by-step explanation:

[tex]0.25=\frac{x}{140} \\140*0.25=\frac{x}{140}*140\\35=x[/tex]

1st box: 140

2nd box: 140

3rd box: 35

Here we want to make a system of equations and solve it, in this way, we will see that there are 8 black sheep.

first, let's define the variables:

x = number of black sheep

y = number of white sheep.

We know that:

"there are 56 sheep"

Then we can write:

[tex]x + y = 56[/tex]

We also know that there are 6 times as many white sheep than black sheep, this means that:

[tex]y = 6 \cdot x[/tex]

Then we have a system of equations:

[tex]x + y = 56[/tex]

[tex]y = 6\cdot x[/tex]

To solve this we need to start by isolating one of the variables in one of the equations. Here, we can see that the variable y is already isolated in the second equation, so we can use that.

Now we can replace that variable in the other equation:

[tex]x + y = 56[/tex]

[tex]x + 6\cdot x = 56[/tex]

Now we can solve this for x, the number of black sheep:

[tex]7\cdot x = 56\\\\x = 56/7 = 8[/tex]

There are 8 black sheep.

Step-by-step explanation:

length of 1st piece = x inch

length of 2nd piece = 3x inch

length of 3rd piece = 4x inch

x + 3x + 4x = 56

8x = 56

x = 7

Thus,

length of 1st piece = 7 inch

length of 2nd piece = 3 × 7 = 21 inch

length of 3rd piece = 4 × 7 = 28 inch

Answer:

y = 10

Step-by-step explanation:

So, we can use the external angle as the measurement of the distant angles. In other words,

4y + 7y + 6 = 116

11y + 6 = 116

11y = 110

y = 10

Answer: 200 miles

Step-by-step explanation:

Answer:

a) 0.19

b) 0.9689

c) ≈ 6 cars

Step-by-step explanation:

Rate at which cars arrive = 12 cars/hour = 1/5 cars/minute

time needed by each car to complete ATM transaction = 6 minutes = 1/6 car/minute

capacity of lane = 10 car

n = 10

a) Calculate the probability of an arriving not using the ATM because the line is full

p ( not using the ATM ) = 0.19

b) probability that a car will not be able to use the ATM machine immediately on arrival

P ( n > 0 ) = 1 - Po

                 = 1 - 0.0311 = 0.9689

c) Average number of cars in the lane

Lq = 5.74 ≈ 6 cars
