A store sells 3 T-shirts for 28.14

The points that he average on the last two tests will be 93 points.

A mean is the average of the set of numbers that are given.

On the first five tests that he took, he averaged 86 points. The total points will be:

= 86 × 5

= 430 points

He averaged 88 points on all seven tests. The total will be:

= (88 × 7)

= 616 points

The point average on the last two tests will be:

= (616 - 430)/2

= 186/2

= 93 points

Given that a cake was baked for her  siblings.

Her big brother ate large part of the cake that is 1/8.

Her sister ate 3/4 of the cake.

We need to find the left out cake for her.

To do that we have to remove 1/8 and 3/4 from 1.

Rule for a dilation with center (0,0)

k is the scale factor.

For point P (0,3):

Using concepts of statistics, we got 7% people are from age 18-24,and 15% for criminal arrests,65 and older are in 13% population and cover less than 1% crime rate.

The topic of crime in the United States is very large, technically covering any action that is punishable under a state or federal law. Any analysis of the topic  requires division into further sub-categories. One common way to do this is  by limiting analysis to crimes involving jail time (i.e. misdemeanors and felonies, which generally differ via the length of jail time involved), then differentiate between violent crimes or property crimes. Violent crimes are described as offenses which involve force or the threat of force, while property crime majorly includes offences involving the taking of money or property, but where there is not any  force or threat of force against the victims. Property crimes are outnumbering violent crimes in the U.S. in 2020, numbering 6.45 million and 1.31 million respectively. Larceny was the actually most common property crime with 4.6 million incidents, while the aggravated assaults accounted for around two thirds of violent crimes.

Hence, percentage of people whose age is in between 18-24 is 7%,

people from age 18-24 engaged in illegal work=15%,

percentage of people whose age is 65 or more than =13%,

people involved in crime having age more than or equal to 65=1%

The measure of ∠ A is 44 degrees.

Given that:-

∠ A and ∠ B are complementary angles.

∠ A = (6x +2) degrees

∠ B = (4x + 18) degrees

We have to find the measure of ∠ A.

We know that the sum of two complementary angles is 90 degrees.

Hence, we can write,

(6x + 2) + (4x + 18) = 90

(6x + 4x) + (2 + 18) = 90

10x + 20 = 90

10x = 90 - 20

10x = 70

x = 70/10

Answer:

Step-by-step explanation:

Factorize the polynomial using the given details.

Since one of the factors known, try to factor it out and futher:

Find its zero's:

Answer:

[tex]x=1, \quad x=\dfrac{3}{2}, \quad x=2[/tex]

Step-by-step explanation:

Factor Theorem

If f(x) is a polynomial, and f(a) = 0, then (x – a) is a factor of f(x).

If the coefficients in a polynomial add up to 0, then (x - 1) is a factor.

Given polynomial function:

[tex]f(x)=2x^3-9x^2+13x-6[/tex]

Sum the coefficients:

[tex]\implies 2-9+13-6=0[/tex]

As the sum of the coefficients is zero, (x - 1) is a factor.

Therefore:

[tex]\implies f(x)=(x-1)(ax^2+bx+c)[/tex]

Expand the brackets:

[tex]\implies f(x)=ax^3+bx^2+cx-ax^2-bx-c[/tex]

[tex]\implies f(x)=ax^3+(b-a)x^2+(c-b)x-c[/tex]

Compare the coefficients with the given polynomial.

As the coefficient of the leading term of the polynomial is 2:

[tex]\implies a=2[/tex]

As the coefficient of the term in x² is -9:

[tex]\implies b-a=-9[/tex]

[tex]\implies b-2=-9[/tex]

[tex]\implies b=-7[/tex]

As the constant of the given polynomial is -6:

[tex]\implies c=6[/tex]

Substitute the found values of a, b and c into the factored form of the polynomial:

[tex]\implies f(x)=(x-1)(2x^2-7x+6)[/tex]

Factor the quadratic:

[tex]\implies 2x^2-7x+6[/tex]

[tex]\implies 2x^2-4x-3x+6[/tex]

[tex]\implies 2x(x-2)-3(x-2)[/tex]

[tex]\implies (2x-3)(x-2)[/tex]

Therefore, the fully factored polynomial is:

[tex]\implies f(x)=(x-1)(2x-3)(x-2)[/tex]

To find the zeros, set the function to zero:

[tex]\implies f(x)=0[/tex]

[tex]\implies (x-1)(2x-3)(x-2)=0[/tex]

Apply the zero-product property:

[tex]\implies x-1=0 \implies x=1[/tex]

[tex]\implies 2x-3=0 \implies x=\dfrac{3}{2}[/tex]

[tex]\implies x-2=0 \implies x=2[/tex]

Therefore, the real zeros of the given polynomial are 1, ³/₂ and 2.

The equivalent expression of  4(8g + 5) + 6 is 4(5 + 8g) + 6

Equivalent expressions are expressions that work the same even though they look different.

In other words, two expressions are said to be equivalent if they have the same value irrespective of the value of the variable(s) in them.

Therefore, let's find the equivalent expression of 4(8g + 5) + 6.

Hence,

4(8g + 5) + 6

32g + 20 + 6

The given scatterplot has no correlation. This is because there is no pattern among the dots on the scatterplot.

Correlation is a measure that is used in statistics to measure the linear relationship that exists between two variables. Correlation can either be positive, negative or zero. The closer the correlation coefficient is to one, the higher the correlation.

Positive correlation is when two variables move in the same direction. When drawn on a scatterplot, the line of best fit is upward sloping. The coeffect of correlation for positive correlation is always positive.

Negative correlation is when two variables move in different directions.  When drawn on a scatterplot, the line of best fit is downward sloping. The coeffect of correlation for negative  correlation is always negative.

Zero correlation or no correlation is when there is no relationship between the variables. When drawn on a scatterplot, there is no discernible patterns among the variables.

The angle measures in this problem are given as follows:

1. Angle SVT: 79º.

2. Angle BEC: 65º.

Angles SVT and SVR are vertical, meaning that they have the same measure, hence we can find the value of y as follows:

8y - 33 = 5y + 9

3y = 42

y = 42/3

y = 14.

Hence the measure of the angle SVT is of:

m<SVT = 5y + 9 = 5(14) + 9 = 79º.

The two angles given in this problem are also vertical, meaning that we can solve for x as follows:

5x - 10 = 3x + 40

2x = 50

x = 50/2

x = 25º.

Then the bottom angle is:

3 x 25 + 40 = 115º.

The bottom angle is supplementary with angle BEC, hence we can find the measure of angle BEC as follows:

m<BEC = 180 - 115

m<BEC = 65º.

Now the value of n will be,

→ n - (3/8) > (-2/5)

→ n > (-2/5) + (3/8)

→ n > (-16/40) + (15/40)
