Which point is a reflection of (-3,-3) across the y-axis?
(-3, 3)
(3, 3)
0 (-3,-3)
o
(3,-3)

Answer:

2y - 15

Step-by-step explanation:

well 15 LESS than TWICE a number. okay so let’s start off by making a variable for the unknown number.... y. the variable is y. so now we have to think, TWICE that number, but we don’t know the number.

Now that we have the variable and we know it has to be doubled, let’s start off making the first half... we can out that into 2y. which is 2 multiplied by the unknown number.

now that we have the first half done, we have to take the 15 less. Less can mean  or subtract in this kind of situation. but for this certain scenario, it will be subtraction. so the equation would be 2y - 15.

Hello!

First of all, let the number be r.

"twice a number" means we multiply that number by 2:

2r

Subtract 15 (fifteen less)

2r-15

This is equal to 21:

2r-15=21

[tex]\rule{160}{2}[/tex]

Solve the equation:

2r=21+15

2r=36

Divide both sides by 2:

r=18

Hope everything is clear.

Let me know if you have any questions!

Answer:

A

Step-by-step explanation:

The expression that is equal to 3B - C in standard form is 2.0 × 10¹

From the question, we are to determine the value of the expression

The given expression is

3B - C

From the given information,

B = p + 6

and

C = 3p - 2

Putting the the values of  B and C into the expression, we get

3B - C = 3(p + 6) - (3p -2)

= 3p + 18 -3p + 2

= 3p - 3p + 18 + 2

= 20

= 2.0 × 10¹

Hence, the expression that is equal to 3B - C in standard form is 2.0 × 10¹

Step-by-step explanation:

Answer: a. It is commonly referred to as the arithmetic average.

b. It is algebraically defined (that is, there is an equation you can use to calculate its value).

c. It is easily influenced by extreme scores.

Step-by-step explanation:

The mean is also referred to as the "average" and it is gotten by adding every number and the dividing the value gotten by the number of the numbers used for the calculation.

It should be noted that the mean is algebraically defined and can be easily influenced by extreme scores.

Midpoint formula:

[tex](\frac{x_1 + x_2}{2} , \frac{y_1 + y_2}{2})[/tex]

So,

(6 / 2 , 6 / 2)

(3, 3)

Midpoint coordinate: (3, 3)

She still has 60%

Step-by-step explanation:

First you make the 25 a 100 which is basically multiply by 4 which you should do the same for 10

so 40/100 is how much she game away

She gave away 40%

She still has 60%

The percent of the roses does Ally still have is 60%.

Given that,

Answer:

Step-by-step explanation:

Where a transversal (t or u) crosses parallel lines (m and n), there are four angles formed at each intersection. Corresponding and vertical angles are congruent.

Angles in a linear pair are always supplementary. Of course, the angles interior to a triangle always total 180°. These facts let you find the relationships of all the angles in the figure.

Angle 13 corresponds to the given angle 52°, so has the same measure. Angles 4 and 18 are vertical angles with respect to those, so also have the same measure. Angles 1 and 3, 14 and 17 are supplementary to the ones just named, so all have measure 128°.

In the same way, angles on the other side of the figure can be found from the one marked 44°. Angles 5, 12, and 15 also have that measure; and angles 2, 6, 11, and 16 are supplementary, 136°. Angles 7 and 10 finish the triangle interior so that its sum is 180°. That means they are 180° -52° -44° = 84°. Of course, angles 8 and 9 are the supplement of that value, 96°.

Answer:

the answer is 18π/5

Step-by-step explanation:

A Central angle (θ) measured in radians tells us how many times the radius fits into the arc.

arc length ÷ radius = θ

arc length = θ · radius

S = 3π/5 · 6 cm

S = 18π/5 cm

Therefore the answer is 18π/5

Answer:

Step-by-step explanation:

Let the exponential function for the given table is,

f(x) = a(b)ˣ

Here, f(x) = Price of the item after 'x' years

a = Initial price of the item

b = Growth factor

x = Duration(years) from year 1913

By exponential regression calculator,

Exponential function represented by the table will be,

f(x) = 7.822(1.034)ˣ

Now we have to calculate the price of the item in year 2025.

Difference in time = 2025 - 1913

                              = 112 years

Price of the item after 112 years,

f(112) = 7.822(1.034)¹¹²

        = $330.840

We fail to reject the null

Step-by-step explanation:

Given the data: 1298; 1229.96; 1193.07; 1279; 1224.98; 1229.97; 1269.98; 1248

Mean price, μ = 1249

Standard deviation, σ = 25

Variance, σ² =

Null hypothesis, H0 : σ² = 25²

Alternative hypothesis, H1 : σ² > 25

Using calculator, the sample standard deviation :

Sample standard deviation = s = 34.072

Sample size, n = 8

For chi² distribution :

X² = [(n - 1)s²] ÷ σ²

X² = [(8 - 1)*34.072^2] ÷ 25^2

X² = (7 * 1160.901184) / 625

X² = 13.002093

Using the Pvalue from Chisquare calculator, df = 8 - 1 = 7; α = 0.05

Pvalue =0.07206

0.07206 > 0.05

Since , Pvalue > α

We fail to reject the null; there is insufficient evidence to conclude that standard devuatue do selling a computer is greater than 25
