What is the equation of the line of best fit that Brianna drew?

A. y=1/2x+5
B. y=1/2x+7
C. y=2x+5
D. y=2x+7​

Answer:

Step-by-step explanation:

A.)

[tex]a^{2} + b^{2} = c^{2}[/tex]

[tex]16^{2} +20^{2}= c^{2}[/tex]

256 + 400 = [tex]c^{2}[/tex]

656 = [tex]c^{2}[/tex]

25.6 = c

__________________________________________________________

B.)

[tex]a^{2} + b^{2} = c^{2}[/tex]

[tex]25^{2}+ 10^{2} = c^{2}[/tex]

625 + 100 = [tex]c^{2}[/tex]

725 = [tex]c^{2}[/tex]

26.9 = c

__________________________________________________________

C.)

[tex]a^{2} + b^{2} = c^{2}[/tex]

[tex]12^{2} +10^{2}= c^{2}[/tex]

144 + 100 = [tex]c^{2}[/tex]

244 = [tex]c^{2}[/tex]

15.6 = c

__________________________________________________________

D.)

[tex]a^{2} + b^{2} = c^{2}[/tex]

[tex]26^{2}+ 24^{2} =c^{2}[/tex]

676 + 576 =  [tex]c^{2}[/tex]

1,252 =  [tex]c^{2}[/tex]

6 * 5 = 30

42 - 30 = 12

? * 2 = 12

? = 6

Answer: A) 6 in^2

First, you need to find the length of the base.

a = 3, b = ?, c= 5

Using Pythagorean Theorem*: a^2 + b^2 = c^2

b^2 = c^2 - a^2

b^2 = 5^2 - 3^2

b^2 = 25 - 9

b^2 = 16 (square root both sides)

b = 4

Now, you have to find the area using the area of a triangle formula: A = (bh)/2

A = (bh)/2

A = (4·3)/2

A = 12/2

A = 6 in^2

Pythagorean Theorem is used for this question since it's a right triangle.

Answer: A) 6in^2

Step-by-step explanation:

base = 4 in

height = 3 in (pythagorean theorem)

A = (bxh)/2 = (4x3)/2 = 12/2 = 6 in^2

Step-by-step explanation: The prime factorization of number is the break down into factors which are prime numbers (numbers without factors except 1 and itself). The factors 22 and 32 are composite numbers since they have more than 1 and itself as factors. They are not prime.

However, the factorization of 22 * 32 * 5 will equal a number. 22*32*5 = 3, 520. But it does not match the solutions given.

Answer:

A. $4.80 + $2.40 = $7.20

Step-by-step explanation:

10% is the same as 10/100 or 1/10. To find 10% of a number, move the decimal point one place to the left.

10% of $48 is $4.80

Now he needs 5% of $48 which is half of 10% of $48, so 5% of $48 is $2.40.

$4.80 + $2.40 = $7.20

Answer: A. $4.80 + $2.40 = $7.20

The dog has been dieting for 19 weeks.

The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.

According to the given problem,

Starting weight of the dog = 89.5 pounds

Halfway weight of the dog = 80 pounds

Weight the dog loses per week = 0.5 pounds

Weight loss = (89.5 - 80) pounds

                    = 9.5 pounds

If the dog loses 0.5 pounds in 1 week,

Then the dog will lose 9.5 pounds in (9.5 × 2) weeks

⇒ The dog will lose 9.5 pounds in 19 weeks.

Hence, we can conclude that the dog has week dieting for 19 weeks and lost 9.5 pounds.

Answer:

Yes, the probability distribution is valid.

Step-by-step explanation:

Given :

Income range ___ midpoint(x) ___ %

5 - 15 __________ 10 _____20%

15 - 25 _________ 20 _____13%

25- 35 _________ 30 _____ 21%

35 - 45 _________40 _____ 17%

45 - 55_________ 40 ____ 20%

55 or more _______ 50 _____9%

Yes, we do have a valid probability distributuon ; as the summation of the percentage values is equal to 100%

Yes. Using the income midpoints  x and the percent of super shoppers, we can conclude that we have a valid probability distribution.

Given:

Income ranges: 5-15, 15-25, 25-35, 35-45, 45-55, 55 or more.

Midpoints x:       10,     20,      30,      40,       50,      60

Percent of super shoppers: 20%, 13%, 21%, 17%, 20%, 9%.

A valid probability distribution has two must have properties:

Its probabilities are non-negative.

Its probabilities sum to 1.

In the given data, the percentages can be converted to probabilities by dividing by 100 as :

0.2, 0.13, 0.21, 0.17, 0.2, 0.09

None of the probabilities are negative.

All probabilities add up to 1

[tex]0.2 + 0.13 + 0.21 + 0.17 + 0.2 + 0.09 = 1[/tex]

Thus, given distribution is a valid probability distribution.

Answer:

x = 14

Step-by-step explanation:

For complementary angles, the sum of two angles is equal to 90 degrees.

We have,

[tex]m\angle ABC = 4x-10\\\\m\angle DBC = x+30[/tex]

ATQ,

[tex]4x-10+x+30=90[/tex]

Taking like terms together,

4x+x =90-30+10

5x = 70

x = 14

So, the value of x is 14.

Answer:

The answer would be 28 becasue if you divide th right number by the m substitue that for the number 97

The sum of the expressions for n = -2 and m = 5 is -43

We have the following expressions (3m + 2n − 6) and (− 4 − 6m + 7n).

We can write the sum of the expression as -

(3m + 2n − 6) + (− 4 − 6m + 7n)

3m + 2n - 6 - 4 - 6m + 7n

3m - 6m + 2n + 7n - 6 - 4

- 3m + 9n - 10

At n = - 2 and m = 5, we get -

(- 3 x 5 + 9 x -2 - 10)

- 15 - 18 - 10

- 43

Therefore, the sum of the expressions for n = -2 and m = 5 is -43.

Given:

In [tex]\Delta ABC, \overline{CA}=\overline{CB}[/tex].

[tex]\overline{CD}[/tex] is an altitude drawn from C to [tex]\overline{AB}[/tex].

To prove:

[tex]\overline{CD}[/tex] bisects [tex]\overline{AB}[/tex].

Proof:

In [tex]\Delta ABC[/tex], [tex]\overline{CD}[/tex] is an altitude drawn from C to [tex]\overline{AB}[/tex].

It means, [tex]\Delta ACD\text{ and }\Delta BCD[/tex] are right angle triangles.

In [tex]\Delta ACD\text{ and }\Delta BCD[/tex],

Hypotenuse : [tex]\overline{CA}=\overline{CB}[/tex]       [Given]

Leg : [tex]\overline{CD}=\overline{CD}[/tex]       [Common]

If the hypotenuse and leg of one right triangle are congruent to the hypotenuse and leg of another right triangle, then by HL postulate both triangles are congruent.

[tex]\Delta ACD\cong \Delta BCD[/tex]        [HL postulate]

[tex]\overline{AD}\cong \overline{BD}[/tex]       [CPCTC]

[tex]\overline{AD}=\overline{BD}[/tex]

It means, point D is the midpoint of [tex]\overline{AB}[/tex].

So, [tex]\overline{CD}[/tex] bisects [tex]\overline{AB}[/tex].

Hence proved.
