Can someone help me find the area of the triangle

please!!!

Answer:   I think its c sorry if im whrong

Answer:

30%

Step-by-step explanation:

The required real-world problem is below that can be solved using the equation.

The equation is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are equal.

A construction company is building a new housing development and wants to know how many houses they need to build to reach a certain profit margin. They know that each house costs $9 to build and they want to sell each house for $21.

If they build x number of houses, the equation to calculate their profit is:

21x - (4x + 9) = profit.

To reach a certain profit margin, the company can set that equation equal to a specific value and solve for x.

Answer:

√25 is a rational number

√1 is rational number

√7 is irrational number

Step-by-step explanation:

first one is √25

=√25

=√5² ( 25 is the square of 5)

= 5

another one is √1

= √1

=√1² ( 1 is the square of itself)

= 1

last one is √7..... and it is irrational

Answer:

33 1/3

Step-by-step explanation:

Answer:

x=50/3y

y=50/3x

Step-by-step explanation:

Isolate the variable by dividing each side by factors that don't contain the variable.

Answer:

-1.2*-7=8.4   -2.5*-2=5   2.5*-2=-5    -1.2*7=-8.4

Answer:

29,30,31

this is basically like counting just add 1

Answer:

y=-1x-1

Step-by-step explanation:

m=y2-y1/x2-x1

(-3)-1=-4

2-(-2)=4

-4/4=(-1)

y=mx+b

-3=-1(2)+b

-1*2=-2

-2-(-2)=0

(-3)-(-2)=(-1)

b=-1

hope this helps :3

if it did pls mark brainliest

Answer:

So... for problem 15. im gonna help you and maybe you'll understand how to do it:) So the X axis is the horizontal line and the Y axis is the vertical line.

So when it says X -4

                          Y 5

Then the point would be at -4 on the horizontal line and 5 positive points on the Y axis (vertical line)

Step-by-step explanation:

I really hope this helps you its hard to describe over type:(

Good luck:))

Answer:

The width of the confidence interval is going to be wider

Step-by-step explanation:

When we Increase the level of confidence without changing the sample size the width of the confidence interval is going to be affected in the following way;

The margin of error (M.E) is going to be larger or be increased. This increase is due to the fact that the critical value is going to increase. Then the increased margin of error would cause the width of the confidence interval to become wider.

This answers your question.

Answer:

(1)Hoops shadow would be 6 ft (2) model would be 3 cms

Step-by-step explanation:

9 / 3 = 3   3 x 2 = 6 ft

15 / 5 =3    3 x 1 = 3 cm

The answer is c...

y = mx + b is slope intercept form

This equation corresponds to that...

to be in slope intercept form:

y = mx + b is corresponded to y = 4x + 9

Answer:

Answer:

x<-2

Step-by-step explanation:

You first subtract 4 from both sides. Then you divide both sides by -8 (note: when you multiply or divide by a negative the sign flips. Then you get your answer

Answer:

The standard deviation for the number of defects per batch is 0.87.

Step-by-step explanation:

Let X denote the number of defective batteries per batch.

A company manufactures batteries in batches of n = 26.

It is provided that the rate of defects is, p = 0.03.

Each battery is defective independently of the others.

The random variable X follows a binomial distribution.

The standard deviation of a binomial distribution is:

[tex]\sigma=\sqrt{np(1-p)}[/tex]

Compute the standard deviation for the number of defects per batch as follows:

[tex]\sigma=\sqrt{np(1-p)}[/tex]

  [tex]=\sqrt{26\times 0.03\times (1-0.03)}\\\\=0.86982757\\\\\approx 0.87[/tex]

Thus, the standard deviation for the number of defects per batch is 0.87.

Answer:

-4+(-3)= -7. The dolphin is -7 feet below sea level

Step-by-step explanation:

Start at -4 on the number line. When you add a negative number to a negative number, you move left on the number line. Move 3 units to the left to land at -7. The dolphin is 7 feet below sea level.
