Find the probability that
x <= -3

Find The Probability That X &lt;= -3

Answers

Answer 1

Answer:

30%

Step-by-step explanation:

there are two numbers that fit in the x<=3 category, those being -3 and -5, so you add the two decimals for them (.17 and .13) to get .30 and move the decimal two times to the right to make it in percentage form.

Answer 2

The probability of P(x ≤ -3) is 0.30 or 30% if the probability table is provided.

What is probability?

It 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.

We have given a probability table in the picture.

P(x ≤ -3) = P(x = -5) + p(x = -3)

From the table:

P(x ≤ -3) = 0.17 + 0.13

P(x ≤ -3) = 0.30 or 30%

Thus, the probability of P(x ≤ -3) is 0.30 or 30% if the probability table is provided.

Max purchased a box of green tea mints. The nutrition label on the box stated that a serving of three mints contains a total of 10 calories. Write an equation that represents C(x). Where C(x) represents the number of calories in 'x' mints. A full box of mints contains 180 calories. Determine the total number of mints in the box.

I WILL GIVE BRANLIEST PLEASE JUST ANSWER BRUV

Answers

Answer: equation is

c(x)=(10/3)x

54 mints per box

Step-by-step explanation: ok so 3 mints=10 calories

if you input 3 for number of mints, ou get 10 for caloires

10=k3

divide both sides by 3

10/3=k

therfor

C(x)=(10/3)x

full box =180 caloies

therefor

full=180=(10/3)x

multiplyboth sides by 3/10 to clear fraction (since 10/3 times 3/10=30/30=1)

540/10=x

54=x

Leah predicts that she will need to contribute $7,000 per year for college tuition and already has $4,000 in savings. She is beginning her Junior year in high school and knows she has 2 years to save to pay for her first year. How much does Leah need to put into her savings account each month to pay for her first year?

Answers

Answer:

125 Dollars

Step-by-step explanation:

Total fee = 7000

Amount in hand = 4000

Amount to be saved in 2 years = 7000 - 4000 = 3000

No of months in 2 years = 12 x 2 = 24

Per month saving = 3000 / 24 = 125 $

The area of a rectangular field is 7371 m2. If the length of the field is 91 meters, what is its width?

Answers

Answer:

81 m

Step-by-step explanation:

From the question given above, the following data were obtained:

Area (A) = 7371 m²

Length (L) = 91 m

Width (W) =?

Area of a rectangle is given by the following equation:

Area = Length × Width

A = L × W

With the above formula, we can obtain the width of the rectangular field as follow:

Area (A) = 7371 m²

Length (L) = 91 m

Width (W) =?

A = L × W

7371 = 91 × W

Divide both side by 91

W = 7371 / 91

W = 81 m

Thus, width of the rectangular field is 81 m

The difference between 25 and a number is at least 13.

Answers

Answer:

x ≤ 12

Step-by-step explanation:

The problem can be represented by the equation:

25 - x = y and y ≥ 13

So, we find that 25 - 12 = 13, which means that any number greater than 12 would result in a difference lower than 13. This sets 12 as the maximum.

What does A U B mean?

Answers

Answer:

Math:The Union of A and B is the set of all those elements which belong either to A or to B or both A and B. use the notation A U B (which is read as 'A union B') to denote the union of set A and set B.

Algebra: n(A U B) = n(A) + n(B) - n(A n B) so 20 = n(A) + 10 - 5 OR n(A) = 15.

Help find the mean ,median,mode to 12,9,15,19,20,15

Answers

Answer:

Mean = 16

Median = 15

Mode = 15

Step-by-step explanation:

Mean - Add all numbers together then subtract from how many numbers are there.

Median - Arrange your numbers in numerical order. Then count how many numbers you have. If you have an odd number, divide by 2 and round up to get the position of the median number. If you have an even number, divide by 2. Go to the number in that position and average it with the number in the next higher position to get the median.

Mode - This question has one mode because there is only one number that occurs more that the rest.

Maya has a car loan of $31,470. The loan has a simple interest rate of 5% per year.

What is the amount of interest that Maya will be charged on this loan at the end of one year?

Answers

Answer:

$1573.50

Step-by-step explanation:

First, converting R percent to r a decimal

r = R/100 = 5%/100 = 0.05 per year,

then, solving our equation

I = 31470 × 0.05 × 1 = 1573.5

I = $ 1,573.50

The simple interest accumulated

on a principal of $ 31,470.00

at a rate of 5% per year

for 1 year is $ 1,573.50.

Answers

Answer:

v=15t/(w+30)

Step-by-step explanation:

multiply by w

wv=15(t-2v)

expand brackets

wv=15t-30v

+30v on both sides

wv+30v=15t

factorize to remove v

v(w+30)=15t

divide by (w+30)

v=15t/(w+30)

After making {v} the subject of the formula, we get -

v = 15t/(w + 2).

What is algebraic expression?

An algebraic expression in mathematics is a combination of terms both constant and variable. For example, we can write the algebraic expressions as -

2x + 3y + 5

2z + y

x + 3y

Given is to make {v} the subject of the formula -

w = 15(t - 2v)/v

The given equation is -

w = 15(t - 2v)/v

w = 15t/v - 2v/v

w = 15t/v - 2

w + 2 = 15t/v

v = 15t/(w + 2)

Therefore, after making {v} the subject of the formula, we get -

v = 15t/(w + 2).

Is it possible to use substitution to solve a system of linear equations if one equation represents a horizontal line and the other equation represents a vertical line?

Answers

Answer:

No

Step-by-step explanation:

Horizontal line:

y = k

Vertical line:

x = m

The intersection is (m, k)

No substitution is possible, as no variables to substitute

No

One is horizontal lines

That should be in this form

y=a

a is any number

A line is vertical

x=b

Look at both equations

a and b are not equal plus there is no x in horizontal line and no y in vertical line.

There is nothing to substitute
