The probability of drawing purple and green marbles will be 1/80.

The probability of an event occurring is defined by probability.

Probability is also called chance because if you flip a coin then the probability of coming head and tail is nothing but chances that either head will appear or not.

As per the given,

Number of purple marble = 5

Number of green marble = 1

Total marble = 5 + 6 + 8 + 1 = 20

Probability drawing a purple marble = 5/20

Probability of drawing a green marble = 1/20 (because the number of marble remain the same)

Probability of drawing a purple and green = 5/20 x 1/20 = 1/80

Hence "There is a 1/80 chance of drawing purple and green marbles.".

The measures are  NE = 7.5 units, GO = 9 units, AG = 12 units, and the perimeter of the ΔOAG is 36 units.

What is the perimeter of the triangle?

A triangle's perimeter is measured in the same unit as its side lengths. If the lengths of its sides are measured in a different unit, first convert them to that unit.

We have,

OA = (4x + 3)  .............(1)

NE = (2.5x)     .............(2)

RN = 4.5         .............(3)

ER = (2x)         .............(4)

Mid-point segment of the triangle

EN = 1/2(OA)         .............(5)

from equations (1), (2), and (5)

2.5x = 1/2(4x + 3)

5x = 4x + 3

x = 3           .............(6)

OA = 4x + 3 = 15

NE = (2.5x) = 7.5

ER = (2x) = 6

RN = 1/2(GO)

GO = 2 * RN = 2 * (4.5)

GO = 9

ER = 2x = 2*3 = 6

AG = 2(ER) = 2 * 6 = 12

The perimeter of the OAG is OA + AG + GO = 15 + 12 + 9

= 36 units.

Hence, the asked measures are  NE = 7.5 units, GO = 9 units, AG = 12 units, and the perimeter of the ΔOAG is 36 units.

We can add 10 pounds of mixed nuts that contain 20% peanuts by solving equations.

Algebraically speaking, an equation is a statement that shows the equality of two mathematical expressions.

For instance, the two equations 3x + 5 and 14, which are separated by the 'equal' sign, make up the equation 3x + 5 = 14.

So, the quantity of mixed nuts we need is x pounds.

There are 0.70 pounds of peanuts in this mixture.

3 pounds of peanuts make up the 20% mix, or 0.20*15.

We got the equation:

0.70 x + 3 = 0.40(x + 15)

Now, solve this equation as follows:

0.70 x + 3 = 0.40(x + 15)

0.70 x + 3 = 0.40(x + 15)

0.70x + 3 = 0.40x + 6

0.70x - 0.40x = 6 - 3

0.30x = 3

x = 10 pounds

Therefore, we can add 10 pounds of mixed nuts that contain 20% peanuts by solving equations.

Answer:

x = 13

Step-by-step explanation:

Given equation,

→ x - (6/2) = 10

Now the value of x will be,

→ x - (6/2) = 10

Hence, the value of x is 13.

When Bobby takes out a mortgage for $30 years at 4% interest with $835.48 in monthly payments, the total principal loan amount is $255644.

In essence, percentages are fractions with a 100 as the denominator. We place the percent symbol (%) next to the number to indicate that the number is a percentage. For instance, you would have received a 75% grade if you answered 75 out of 100 questions correctly on a test (75/100).

Here,

The interest paid per month=$835.48

Interest paid in 30 years=835.48*12*30

Rate of interest=4%=0.04

Time=30 years

Principal=I/RT

=(835.48*30*12)/(0.04*30)

Answer:

if the base is on the x-axis, the width of the rectangle is = xif the height is based on the parabola, the length = 7-x^2

the area of a rectangle = length * width

thus, area = x*(7-x^2)= 7x-x^3

in order to maximize the area, you would need to take the derivative of the area and set it equal to 0

Area = 7x-x^3Area' = 7 - 3x^2

7-3x^2 = 0thus, x = 1.5275

this x represents the x needed to create the largest possible area with the given parameters.

Thus:Width (x-axis) = 1.5275Length (y-axis) = 7 - (1.5275)^2 = 4.6667

The mid point of the line segment is (1,9)

The general formula to calculate the midpoint is written as

Twice the sum of the number and negative seven is eight. The number can be found as follows:

let

the number  = x

According to the word expression, twice the value of  the addition of x and minus seven is equals to 8. Hence, we will find the value of x in the equation formed from the words expression.

The variable x is the required number.

Therefore,

2(x + (-7)) = 8

2(x - 7) = 8

open the brackets

2(x - 7) = 8

2x  - 14 = 8

add 14 to both sides of the equation

2x  - 14 = 8

2x  - 14 + 14 = 8 + 14

2x = 22

0.137606 the standard error of the average amount of coffee a stat 107 student drinks per day is greater than 12.7 oz.

Data dispersion in regard to the mean is quantified by a standard deviation, or "σ". Statisticians can assess if the data fits into a normal distribution or another mathematical connection using the standard deviation. The average, or mean, data point will be within one standard deviation of 68% of the data points if the data follow a normal curve.

Given that,

Standard deviation (σ) = 5.2 oz

mean (μ) = 10 oz

Number of students (n) = 120

As we know,

P ( z > 12.7 oz.) = P (z > [{x(avg.) - μ[tex]\sqrt{n}[/tex]}/σ])

                        = P (z > [{12.7 - 10[tex]\sqrt{120}[/tex]}/5.2])

The graph that could be used to determine the possible variance levels that would result in an acceptable height is the third graph.

Fron the information, the required model height for the designed clothes should be less than or equal to 5 feet 10 inches. In this case, the equation for the variance in height is of the straight line form;

y = m·x + c

Where x is the height  in inches

Given that the maximum height allowable is 70 inches, when x = 0 we have;

y = m·0 + c = 70

Therefore, c = 70

Also when the variance = 0 the maximum height should be 70 which gives the x and y-intercepts as 70 and 70 respectively such that m = 1

The equation becomes;

y ≤ x + 70

Also when x > 70, we have y ≤ -x + 70   with a slope of -1

Step 1: Start by calculating the area of the base of the storage tank. The area of a circle is calculated by: A = π*r², where r is the radius of the circle.

Step 2: For Emma’s cylindrical storage tank, the radius of the base is 5 feet. Substitute this value in the formula and calculate the area of the base, which is equal to: A = π*5² = 78.54 square feet.

Step 3: Now we need to calculate the volume of the cylindrical storage tank. The volume of a cylinder is calculated by: V = π*r²*h, where r is the radius of the circle and h is the height of the cylinder. For Emma’s tank, the height is 10 feet. Substitute these values in the formula and calculate the volume, which is equal to: V = π*5²*10 = 785.4 cubic feet.

Step 4: Therefore, Emma’s cylindrical storage tank has a capacity of 785.4 cubic feet.
