Answer:

#18)  <em>m</em>∠B = 107°

#19) <em>m</em>∠B = 17°

Step-by-step explanation:

*Supplementary angles are angles who's measures equal 180°

*Complementary angles are angles who's measures equal 90°

#18) If ∠A is 73°, then we must subtract 73 from 180.

180 - 73 = 107

This means that <em>m</em>∠B = 107°.

#19) If ∠A is 73°, then we must subtract 73 from 90.

90 - 73 = 17

This means that <em>m</em>∠B = 17°.

What is the slope of the line that passes through (-2,-3) and (1,1)
kramer
Slope:
m =  \frac{y _{2} - y _{1}}{x_{2} - x _{1}}

Slope is rise over run. It is a ratio of the amount of the y-axis over the amount of x-axis. So, now assign the first group of numbers, (-2,-3) as 1; then the second group, (1,1) as 2. Like this:
first \: group(x _{1} ,y _{1}) \\ second \: group(x_{2},y_{2})
Notice the subscripted numbers designate the group number. Next, plug in the numbers and do the math.
\frac{1 - ( - 3)}{1 - ( - 2)}  =  \frac{1 + 3}{1 + 2}  =  \frac{4}{3}
So, the slope, m, is equal to four thirds.

m = 4/3

You purchase a car using a $20,000 loan with a 5% simple interest rate.
hammer [34]
Simple interest = Cost Price + (Interest Percentage of Cost Price × number of years or months we are paying off)

a) SI = £20 000 + (5% of £20 000 × 4)
SI = £20 000 + (£1000 × 4)
SI = £20 000 + £4000 = £24 000

b) SI = £20 000 + (5% of £20 000 × 3)
SI = £20 000 + (£1000 × 3)
SI = £20 000 + £3000 = £23 000

£24 000 - £23 000 = £1000 that you saved!

What is the length of a radius of a circle whose center is at (1, -2) and whose one point lies on a circle at (-5, 6)?
Arturiano [62]

Answer:

radius = 10

Step-by-step explanation:

The distance from the centre to the point on the circle is the radius r

Calculate r using the distance formula

r = \sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1})^2    }

with (x₁, y₁ ) = (1, - 2) and (x₂, y₂ ) = (- 5, 6)

r = \sqrt{(-5-1)^2+(6-(-2))^2}

  = \sqrt{(-6)^2+(6+2)^2}

  = \sqrt{36+8^2}

   = \sqrt{36+64}

   = \sqrt{100}

   = 10

Determine which of the following graphs is the graph of 8x + 9y - 72.
Fittoniya [83]

Step-by-step explanation:

To figure out your x-intercepts and y-intercepts you have to redo the equation and make it equal to zero.

Step 1: 8x + 9y - 72 = 0

Step 2: 8x + 9y = 72

Now you can figure out your intercepts! As long as you use the STANDARD FORM EQUATION which is Ax + By = C

Y-INTERCEPT (vertical line): ( \frac{c}{b} , 0 )

X-INTERCEPT (horizontal line): ( 0 , \frac{c}{a} )

Insert your numbers how it shows in the standard form equation and you should get something like this:

Y-INTERCEPT: ( \frac{72}{9} , 0 )

<em>Simplified Y-INTERCEPT: </em>( 8 , 0 )

X-INTERCEPT:  ( 0 , \frac{72}{8} )

<em>Simplified X-INTERCEPT: </em><em> ( 0 , 9 )</em>

<em />

Insert that into your graph and you should be able to get your answer.

A basketball player is fouled while attempting to make a basket and receives two free throws. The opposing coach believes there
zzz [600]

Answer:

a)

P(X = 0) = 0.64

P(X = 1) = 0.11

P(X = 2) = 0.25

b) 0.75 = 75% probability that he makes no more than one of the shots

Step-by-step explanation:

We have these following probabilities:

64% = 0.64 probability that he misses both shots, that is, makes none of them.

11% = 0.11 probability that he makes one shot.

25% = 0.25 probability that he makes both shots.

a. Construct the appropriate probability distribution. (Round your answers to 2 decimal places.)

Binomial probability distribution, in which P(X = x) is the probability of making x shots. So

P(X = 0) = 0.64

P(X = 1) = 0.11

P(X = 2) = 0.25

b. What is the probability that he makes no more than one of the shots? (Round your answer to 2 decimal places.)

P(X \leq 1) = P(X = 0) + P(X = 1) = 0.64 + 0.11 = 0.75

0.75 = 75% probability that he makes no more than one of the shots
