Answer: Predicted level of social skill will be 46

Step-by-step explanation:

For a linear regression; the general equation is in the form;

y = mx + c

Where is the predicted value or variable

m = slope or gradient (regression coefficient )

c = intercept which is constant (this is where the line of best for crosses the y-axis.

y = predicted value

x = independent variable

Given the following:

Regression coefficient (m)= 3

Regression constant (c)= 16

Score(x) = 10 (independent variable)

From:

y = mx + c

y = 3(10) + 16

y = 30 + 16

y = 46

Predicted level of social skill will be 46

The radius goes from the center to the edge of the circle.

The diameter is twice as long as the radius; it is a segment going through the center with both endpoints on the circle

The circumference is the distance around the circle. Think of it as the perimeter of the circle.

Answer:

a₁ = 1; r = 3

Step-by-step explanation:

a₁ represents the first term. It is 1 in this case.

r represents the common ratio between terms. In this case it's 3 / 1 = 3.

Answer:

a1 = 1

r = 3

Step-by-step explanation:

a1 = first term = 1

r = common ratio = 2nd term/1st term

Answer:

D;

Step-by-step explanation:

In the Cartesian system and coordinates, we have the 2 dimensional plane and also the 3 dimensional plane.

The two dimensional plane is the more popular one within this level of education where we have one of the coordinates denoting the horizontal distance with the other coordinate denoting the vertical distance.

The one that denotes the horizontal distance is referred to as the x-coordinate with its plane called the x-axis while the one they represents the vertical distance is referred to the y-coordinate and its plane is called the y-axis

In the three dimensional space however, we have the third side which is the z part and it’s called the z-coordinate which is for the z axis

Answer:

Factors: 5x, 3x²y⁵   Not Factor: 10x⁴y³

Step-by-step explanation:

5x is a factor because 15x²y⁶= 5x•3xy⁶

3x²y⁵ is a factor because 15x²y⁶ = 3x²y⁵•5y

10x⁴y³ isn't a factor because 15:10=1.5 isn't integer

Answer:

x=2/5 y−2

Step-by-step explanation:

Answer:

x-intercepts = (-2,0)

y-intercepts = (0,5)

Step-by-step explanation:

First, make the equation into slope-intercept form. (y=mx+b)

y=5/2x+5

b= the y-intercept so y-intercept = 5.

If you graph this line, you can see that the x-intercept = -2.

Answer:

16589.44

Step-by-step explanation:

z score for 99% confidence interval = 2.576

Margin of error = 1% = 0.01

Formula =

Margin of error = z score × p(1 - p)/n

0.01=2.576 × √ (0.25)/n

0.01=2.576 × 0.5/√ (n)

Crops Multiply

0.01× √ (n) = 2.576 × 0.5

divide both sides by 0.01

√(n) = 2.576 × 0.5/ 0.01

√n =128.8

Square bother sides

n = 128.8²

n = 16589.44

2. 25 x 6=150

This is Option D, therefore we have the match:2+D

3. 22 x 6=132

This is Option E, therefore we have the match: 3+E

4. 21 x 8=168

This is Option C, therefore we have the match: 4+C

5. 23 x 7=161

This is Option A, therefore we have the match:5+A

Answer:

Jamie must sprint 107 meter to pass Shelly at point A.

Step-by-step explanation:

Circumference of a sector of the circle is represented by,

Circumference = [tex]\frac{\theta}{360}(2\pi r)[/tex]

where θ = central angle subtended at the center by an arc

r = radius of the circle

[tex]m(\widehat{AB})[/tex] = [tex]\frac{123}{360}(2\pi )(50)[/tex]

           = 34.1667π

           = 107.34 meter

           ≈ 107 meter

Therefore, Jamie must sprint 107 meter to pass Shelly at point A.

Answer:

D. 10 feet

Step-by-step explanation:

40/8 = x/2 --> cross multiply

8x = 80

x = 10

Option D is correct, the person who casts a 2 feet shadow is 10 foot tall.

A ratio is an ordered pair of numbers a and b, written a / b where b does not equal 0.

Given that At a certain time of day, a 40-foot building casts a 8 foot shadow.

We need to find how tall is a person who casts a 2 foot shadow.

Let x be the height of the person.

Let us form a proportional equation

40/8=x/2

Apply cross multiplication

80=8x

Divide both sides by 8

x=10

Hence, the person who casts a 2 foot shadow is 10 foot tall.

Answer:

Step-by-step explanation:

The nth term of an arithmetic sequence is expressed as [tex]Tn = a+(n-1)d[/tex].

a is the first term of the sequence

d is the common difference

n is the number of terms

Given the first term a = 4 and common difference d = 3, we can calculate the first five terms of the sequence using the formula.

If n = 2

[tex]T_2 = 4+(2-1)*3\\T_2 = 4+(1)*3\\T_2 = 4+3\\T_2 = 7\\\\when \ n = 3;\\T_3 = 4+(3-1)*3\\T_3 = 4+(2)*3\\T_3 = 4+6\\T_3 = 10\\\\when\ n = 4\\T_4 = 4+(4-1)*3\\T_4 = 4+(3)*3\\T_4 = 4+9\\T_4 = 13\\\\when\ n = 5\\T_5 = 4+(5-1)*3\\T_5 = 4+(4)*3\\T_5 = 4+12\\T_5 = 16\\[/tex]

The first five terms of the sequence from lowest to highest are 4, 7, 10, 13 and 16

Hey there! :)

Answer:

x = 3.

Step-by-step explanation:

Given:

[tex](8x-8)^{\frac{3}{2} } = 64[/tex]

Rule of fractions in exponents:

Numerator- power

Denominator- root

Take the 2/3 root of both sides:

[tex](8x-8) = 64x^{\frac{2}{3} }[/tex]

Simplify [tex]64x^{\frac{2}{3} }[/tex]

Cube root of 64 = 4

4² = 16.

Therefore:

8x - 8 = 16

Add 8 to both sides:

8x = 24

Divide both sides by 8:

x = 3.

Answer:

6) g = 11p

7) This equation is an example of direct variaction because it is proportional because can make a slanted line with the equation C = 6g + 15

Step-by-step explanation:

Well to find g we seperate g and combine like terms,

[tex]81 = 6g + 15[/tex]

So we subtract 15 from both sides 66 = 6g,

66/6 = 11.

So g = 11.

Answer:

the probability that at least one envelope is a yellow envelope is 16/21

Step-by-step explanation:

The probability that at least one envelope is a yellow envelope is P(Y);

P(Y) = 1 - P(Y)'

P(Y)' is the probability that no envelope is a yellow envelope.

Given;

red envelope = 1

blue envelopes = 3

green envelopes = 2

yellow envelopes = 3

Total = 9

Number of non-yellow envelope = 9 -3 = 6

(6 envelope are not yellow)

P(Y)' = P1 × P2 × P3

Since there is no replacement;

P(Y)' = 6/9 × 5/8 × 4/7

P(Y)' = 5/21

From equation 1;

P(Y) = 1 - 5/21

P(Y) = 16/21

the probability that at least one envelope is a yellow envelope is 16/21.

Answer:

183.26cm

Step-by-step explanation:

Radius of the Circle = 50cm

Let the point be at A

It turns forward 210 degrees to B.

Therefore, the central angle subtended by the arc AB = 210 degrees

The movement of the point from A to B will be the length of the arc AB.

[tex]\text{Length of an arc }=\dfrac{\theta}{360} \times 2\pi r \\$Therefore, the distance moved forward$\\=\dfrac{210}{360} \times 2\times\pi \times 50\\\\=183.26$ cm[/tex]
