I would really appreciate it if someone could answer this It’s due in 20 mins please help :(

Answer:

It would take him 108 minutes to mow the lawn.

Step-by-step explanation:

We can do proportion.

[tex] \frac{5 \: lawns}{36 \: minutes} = \: \frac{15 \: lawns}{x} [/tex]

[tex]36 \times 15 = 540 \\ 5 \times x = 5x[/tex]

[tex] \frac{540}{5} = \frac{5x}{5} [/tex]

[tex]108 = x[/tex]

Answer:

there are 34 green marbles

there are 91 total marbles

Step-by-step explanation:

57 - 23 = 34

57 + 34 = 91

Answer:

the remainder is 58

Step-by-step explanation:

when you use long division and can't fit what you are dividing by into the number, that is your remainder.

Answer:

1/3 of chance

The probability that you will roll doubles will be 1/36.

Probability is defined as the ratio of the number of favourable outcomes to the total number of outcomes in other words the probability is the number that shows the happening of the event.

Probability = Number of favourable outcomes / Number of sample

Given that you have two six-sided dice where each side is equally likely to land face up when rolled.

The favourable outcomes are {2,2} = 1.

Total outcomes = 36

The probability will be calculated as,

Probability = 1 / 36

Answer: V(X) = 0.96

Step-by-step explanation: Variance is defined as the average of the squared difference from the sample or population mean.

For a discrete frequency distribution is calculated following the steps:

1) Determine expected value or mean:

[tex]E(X)=\frac{\Sigma xf}{\Sigma f}[/tex]

[tex]E(X)=\frac{0(700)+1(900)+2(600)+3(300)}{2500}[/tex]

E(X) = 1.2

2) Multiply frequency and the squared difference of x and expected value:

[tex]f(x-E(X))^{2}[/tex]

[tex]700(0-1.2)^{2}=1008\\900(1-1.2)^{2} = 36\\600(2-1.2)^{2} = 384\\300(3-1.2)^{2} = 972[/tex]

3) Add them:

[tex]\Sigma [f(x-E(X))^{2}][/tex] = 1008 + 36 + 384 + 972 = 2400

4) Divide the sum per frequency total:

[tex]V(X)=\frac{\Sigma [f(x-E(X))^{2}]}{\Sigma f}[/tex]

[tex]V(X)=\frac{2400}{2500}[/tex]

V(X) = 0.96

Answer:

Area: 59.5 ft squared

Perimeter: 31.6 feet

Step-by-step explanation:

Area:

For the area of the square, you're going to use the formula length times width. The length and width are both 7, so you'll do 7 times 7, which is 49. Next, you need to find the area of the triangle. It's a bit more confusing since they give you the hypotenuse (7.6 ft), but they did that to try and trick you. The area of a triangle is length times width divided by two. So, you're going to take the width (3) and multiply it by the length (7). The length is 7 because the length of the square and the triangle are the same since the bottom of the triangle is the same length as the top of the square. Anyway, using the formula, you will do 7 times 3 divided by 2, which is 21 divided by 2, which is 10.5. Add the 10.5 to the 49 we got from the square, and you'll get 59.5 feet squared.

Perimeter:

For the perimeter, you just need to add the side lengths. Starting at the top and going to the right, we can add 7.6+7+7. We don't get the left length, but it's the same as the rest of the square (7) because all sides of a square are equal. So, now we have 7.6+7+7+7, which is 28.6, and we just need the last one which is 3, so the final answer is 31.6 feet.
