Allen's score in a video game was changed by −55 points because he missed some targets. He got −11 points for each missed target. How many targets did he miss?

Answers

Answer:

Allen missed 5 targets.

Step-by-step explanation:

You divide -55 by -11 to find how many targets he missed. But when you divide, you have to remember that a negative divided by a negative is a positive, so the answer will be postitive.

-55/-11=5

Slope = - 3/5, y-intercept = 5

Answers

Answer:

y = - [tex]\frac{3}{5}[/tex] x + 5

Step-by-step explanation:

Assuming you require an equation of the line.

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Here m = - [tex]\frac{3}{5}[/tex] and c = 5, thus

y = - [tex]\frac{3}{5}[/tex] x + 5 ← equation of line

44+44= 88 360-88= 272 272/2= 136
136 is your answer. you can also see that 44 degrees is on a straight line so you can do 180 ( because a straight line is 180 degrees) minus 44 which also gives you 136

PLEASE HELP I NEED THIS NOW PLEASE I WILL MARK BRAINLIST!! Look at the image above to solve please

Answers

Answer:
y+119=180( being straight angle)
y=180-119
y=61
Then,
5x+11=y(being corresponding angle)
5x+11=61
5x=61-11
5x=50
x=10

y − 3x = 4 slope intercept form plsssssssss

Answers

Answer:

y = 3x + 4

Step-by-step explanation:

The slope-intercept form of a line is y = mx + b. We add - 3x to 4 to isolate the y.

y= 3x+4. add 3x to both sides to get 3x on the right side, leaving y by itself.

After 200 feet of drilling on the first well, a soil test is taken. The probabilities of finding the particular type of soil identified by the test are as follows. P(soil | high-quality oil) = 0.20 P(soil | medium-quality oil) = 0.80 P(soil | no oil) = 0.20 How should the firm interpret the soil test? The probability of finding oil is good. Given the probability of finding good soil, the oil company is more likely to find oil. What are the revised probabilities?

Answers

Answer:

The revised probabilities are;

The probability of finding soil with oil  = 0.8  

The probability of finding soil with good oil = 0.16

The probability of finding medium quality oil =  0.64

Step-by-step explanation:

The given probability of finding soil with high quality oil, P(QO) = 0.20

The probability of finding soil with medium-quality oil, P(OM) = 0.80

The probability of finding soil with no oil, P(ON) = 0.2

Therefore, given that the probability of finding soil with no oil = 0.2, we have;

The probability of finding soil with oil, P(OP) = 1 - the probability of finding soil with no oil

P(OP) = 1 - 0.2 = 0.8

Which gives;

The probability, P(FG) of finding soil with oil and that the oil is good is given as follows;

P(FG) = P(QO) × P(OP) = 0.2 × 0.8 = 0.16

The probability of finding good oil = 0.16

Similarly;

The probability of finding medium quality oil P(FM) =  P(OM) × P(OP) = 0.8 × 0.8 = 0.64

Which gives the revised probability as follows;

The probability of finding soil with oil, P(OP) = 0.8  

The probability of finding soil with good oil, P(FG) = 0.16

The probability of finding medium quality oil, P(FM) =  0.64.

What is the equation in point slope form of the line that passes through the point (-1, -3) and has a slope of 4?

Oy-1=4(3-3)

Oy+3 = 4(x+1)

Oy+1=4(x+3)

Oy-3 = 4(2 - 1)

Answers

Answer:

The answer is y+3 = 4(x+1)

Step-by-step explanation:

To find an equation of a line in point slope form when given the slope and a point we use the formula

[tex]y - y_1 = m(x - x_1)[/tex]

where

m is the slope

( x1 , y1) is the point

So we have

[tex]y + 3 = 4(x + 1)[/tex]

Problem number 26 of the Rhind Papyrus says: Find a quantity such that when it is added to StartFraction 1 Over 4 EndFraction of itself the result is a 15. The modern day equation that models this problem is x plus StartFraction 1 over 4 EndFraction x equals 15.. What is the solution to the equation? x = 10 x = 12 x = 15 x = 30

Answers

Answer:

[tex] x = 12 [/tex]

Step-by-step explanation:

x = the quantity to find

This quantity added to ¼ of itself gives 15.

Thus, this problem can be represented as given above:

[tex] x + \frac{1}{4}x = 15 [/tex]

Solve for x

[tex] x + \frac{x}{4} = 15 [/tex]

[tex] \frac{4x + x}{4} = 15 [/tex]

[tex] \frac{5x}{4} = 15 [/tex]

Multiply both sides by 4

[tex] \frac{5x}{4}*4 = 15*4 [/tex]

[tex] 5x = 60 [/tex]

Divide both sides by 5

[tex] \frac{5x}{5} = \frac{60}{5} [/tex]

[tex] x = 12 [/tex]

TV−→− bisects ∠STU, m∠STV=(14x+8)∘, and m∠UTV=(x+2)∘. Find m∠STU

Answers

Answer:

Since TV bisects STU, m∠STV and m∠UTV are equal

14x+8 = x+2

13x+8 = 2

13x = -6

x = -6/13 or -0.46

The measure of m∠STU is 40/13 degrees

A point that bisects a line divides the line into two equal parts

If TV bisects  ∠STU and  ∠UTV, then;

∠STU =  ∠STV+  ∠UTV ∠STV=  ∠UTV

Given the following

m∠STV=(14x+8)∘

m∠UTV=(x+2)∘

Substitute the given values into the formula and calculate m∠STU

14x + 8 = x+ 2

14x - x = 2 - 8

13x = -6

x = -6/13

Get m∠STV

m∠STU = 14x+8 + x + 2

m∠STU = 15x + 10

m∠STU = 15(-6/13) + 10

m∠STU = -90/13 + 10

m∠STU = 40/13

Hence the measure of m∠STU is 40/13 degrees
