Can someone help me with questions 2 and 3 pls?

Answer: Is there a total for how many kids like each? If there isn't than this is how I would solve it. For percentage purposes let's say there are 100 students. 50 like math, 50 like science. Half of the students who like math also like science, which means 75 percent of the school likes science. A third of students who like science also like math, and since 75 percent of the school of 100 children likes science, that would mean 1/3 of that is 25, which would mean 75 percentof all students like math. Hence the ratio, I believe, is 1 to 1.

Step-by-step explanation:

Answer:

well if you add the third of students to math and the third of students from science I think thats the answer

Answer:

This is a fairly simple binomial distribution. We know it's binomial, because we're looking for a "fixed" number of patients, not the "first" like a geometric.

You can use your calculator:

binomcdf(n,p,Kr)

n=population, p=probability, Kr=number you're looking for

binomcdf(8,.8,1)

We have to do 1, not 2, because it says fewer than 2, which means 1.

Answer:

13.6

Step-by-step explanation:

The period is double of the distance (on the x-axis) between the maximum and the minimum. In this case, the x-coordinate of the minimum is -10.4, the x-coordinate of the maximum is -3.6, the distance is -3.6 - (-10.4) = 6.8, and the period is 2*6.8 = 13.6

Answer:

[tex]P(A) = \dfrac{1}{4}\\P(B) = \dfrac{1}{13}\\P(A \cap B) = \dfrac{1}{52}\\P(A/B) = \dfrac{1}{4}\\P(A/B) = P(A)\\[/tex]

A and B are not independent events.

Step-by-step explanation:

Total number of possibilities is 52 (Total number of cards in the deck).

Formula for probability of an event E can be observed as:

[tex]P(E) = \dfrac{\text{Number of favorable cases}}{\text {Total number of cases}}[/tex]

For event A, number of cases possible for a card to be diamond = 13

[tex]P(A) = \dfrac{13}{52} \\\Rightarrow P(A) = \dfrac{1}{4}[/tex]

For event B, number of cases possible for a card to be a king = 4

[tex]P(B) = \dfrac{4}{52} \\\Rightarrow P(B) = \dfrac{1}{13}[/tex]

For the event, [tex]A \cap B[/tex], the card is a king and diamond, only one case is possible.

Because there is only one card for king of diamond.

[tex]P(A \cap B) = \dfrac{1}{52}[/tex]

Formula for P(A/B):

[tex]P(A/B) = \dfrac{P(A \cap B)}{P(B)}[/tex]

[tex]\Rightarrow \dfrac{\dfrac{1}{52}}{\dfrac{1}{13}}\\\Rightarrow \dfrac{1}{4}[/tex]

Yes, P(A) is same as P(A/B).

Here, A and B are not independent events because they have a common case i.e. a king is there which is of diamond in the deck.

Answer:

1/13

Yes, events a and b are independent events

Answer:

14.25-d

Step-by-step explanation:

The original amount of money he has is 14.25 so that is the first number in your equation. H ethen buys the card which costs (d) dollars so you are subtracting that from 14.25 since he is spending it. This means the final equation is 14.25-d.

Step-by-step explanation:

You take 30% of 4.75. You multiply 0.30 times 4.75. Then you subract that from 4.75. Boom.

Answer:

$3.33

Step-by-step explanation:

$4.75 by 30 then divide it by one hundred. So, the discount is equal to $1.43. To calculate the sales price, simply deduct the discount of $1.43 from the original price $4.75 then get $3.33 as the sales price.

Answer:

x= 2 and x= -6

Step-by-step explanation:

3(x+2)^2=48

1)   [3(x+2)^2]/3=48/3

2) (x+2)^2 = 16

3) √(x+2)^2 =+/-√16

4) x+2 = 4   and    x+2 = -4

5) x=2          and   x= - 6

Check:

3(x+2)^2=48

3(2+2)^2 = 48           and        3(-6+2)^2=48

48 = 48                                   48=48

Answer:

B

Step-by-step explanation:

175 is the yearly cost which is the constant

The cost is related to the miles so that’s why they’re multiplied together

The total amount of reimbursement the company offers will be C = 0.45x + 175. Then the correct option is B.

A connection between a number of variables results in a linear model when a graph is displayed. The variable will have a degree of one.

The linear equation is given as,

y = mx + c

Where m is the slope of the line and c is the y-intercept of the line.

Joseph's company offers a reimbursement package of $0.45 per mile plus $175 a year for maintenance.

Let 'x' be the number of miles and 'C' be the number total amount. Then the equation of the line is given as,

C = 0.45x + 175

The total amount of reimbursement the company offers will be C = 0.45x + 175. Then the correct option is B.

Answer:

3.25 hours

Step-by-step explanation:

Answers and Step-by-step explanations:

Let's look at the first row:

cost = _______ + _______ * (monthly payment)

The first blank should be the "down payment" because this is the initial, constant value that is paid. The second blank should be the "number of months" because this way, when multiplied by the actual amount each payment is (monthly payment), then we get the total amount paid during those months.

So, we have:

cost = (down payment) + (number of months) * (monthly payment)

Now for the second row, we just plug in numbers and variables:

335 = 50 + 6 * p

Finally, we can solve for p:

335  = 50 + 6p

6p = 285

p = $47.50

Answer:

Cost = down payment + no. of monthly payments × monthly payment

335 = 50 + 6 × p

285 = 6p

p = 47.5

The total monthly mortgage payment for the house is $975.63

A percentage is a number or ratio that can be expressed as a fraction of 100. A percentage is a number or ratio expressed as a fraction of 100. It is often denoted using the percent sign, "%", although the abbreviations "pct.", "pct" and sometimes "pc" are also used. A percentage is a dimensionless number; it has no unit of measurement.

here, we have,

The principle amount is $175000

80% of 175000 is =  = $140000

20% of 175000 is =  = $35000

Emi formula is :

p*r*(1-r)^n/(1-r)^n-1

For 1st part:

p = 140000

r = 4.75/12/100=0.00395

n = 360

Putting values in formula we get

= $729.508

For 2nd part:

p = 35000

r = 7.525/12/100=0.00627

n = 360

Putting values in formula we get

= $245.301

Adding both the monthly payments:

974.809 dollars

This is closest to option A.

So, option A is the answer.

And for 30 years the mortgage payment will be = 351226.80 dollars

Hence, The total monthly mortgage payment for the house is $975.63.

This question is based on the rounding off rule. Therefore, Keisha estimate of the sum is 630.

Given:

Keisha estimates 259 + 372 by rounding each number to the nearest 10.

We need to determined the what is Keisha estimate of the sum.

According to the question,

By using the round- off rule as follows:

Example: 38 rounded to the nearest ten is 40. ...

Example: 33 rounded to the nearest ten is 30.

First we rounding off the 259,

From the first rule, 259 is round the number up.

Therefore, we get the value 260.

Now,rounding off the 372,

From the second rule, 372 is round the number down.

Therefore, we get the value 370.

Now, sum up the both numbers,

260 +370 = 630

Therefore, Keisha estimate of the sum is 630.

OP = RQ - NM = 7 - 3 = 4

PQ = MR - NO = 3 - 2 = 1

Area(OPQ?) = 4×1 = 4

Answer: 4

The area of polygon MNOPQR = Area of a rectangle that is 9 square units + Area of a rectangle that is 4 square units.

The area of a rectangle is defined as the product of the length and width.

The area of a rectangle = L × W

Where W is the width of the rectangle and L is the length of the rectangle

A polygon is given in the question, as shown

The area of polygon MNOPQR = Area of a rectangle that is 9 square units + Area of a rectangle that is ___ square units.

We have to determine the fill-in-the-blank.

As per the given figure, we can see that

OP = RQ - NM = 7 - 3 = 4

PQ = MR - NO = 3 - 2 = 1

Required area of rectangle = 4 × 1 = 4

Hence, the required fill-in blank will be "4".
