Scale drawing
Object
A. Side a is 26 inches long, side bis 20 inches long, and side cis 10
inches long
B. Side a is 15 inches long, side bis 12 inches long, and side cis 7
inches long
C. Side a is 11 inches long, side bis 8 inches long, and side cis 3
inches long
D. Side ais 2.5 inches long, side bis 5 inches long, and side cis 6.5
inches long
Answer: A. Side a is 26 inches long, side b is 20 inches long, and side c is 10.
Step-by-step explanation:
Scale factor for drawing = 2:1
Dimensions of drawing : 10 in, 5 in, 13 in
Dimension of object = Scale factor x Dimension of drawing
Sides of object:
2 x 10 in =20 in [b]
2 x 5 in = 10 in [c]
2 x 13 in = 26 in. [a]
Hence, the correct option is
A. Side a is 26 inches long, side b is 20 inches long, and side c is 10.
Answer:
Side a is 2.5 inches long, side b is 5 inches long and side c is 6.5 inches long.

The graph shows the number of gallons of white paint that were mixed with gallons of yellow paint in various different ratios:
Graph titled Mixing Paint, horizontal axis labeled Yellow Paint in gallons, and vertical axis labeled White Paint in gallons is shown. The horizontal scale is 0 to 24 in increments of 3. The vertical scale is 0 to 168 in increments of 21. The plotted points are 3, 21 and 6, 42 and 9, 63.
The number of gallons of white paint mixed with 1 gallon of yellow paint is ______.
Answer:
the ratio is 1:7
so the answer is 7 gallons of white paint
Step-by-step explanation:
Hope this helps!!
Answer:
7
Step-by-step explanation:
on the graph, it shows that for every 21 gallons of white paint there are 3 gallons of yellow. Then you divide 3 by 21 and the answer is 7.

CHOICE C
Lauren goes to the exhibition. She purchases a table for $44 and 2 chairs. Each of the chairs costs the same price. Write an expression representing the total cost of her purchases with the cost of the chairs as c. Evaluate the total cost if one chair costs $23.
a
$44
b
$90
c
$190
d
$144
Answer:
B: $90.
Step-by-step explanation:
The expression for this problem can be represented as
Total Cost = $44 + 2c
Since one chair costs $23, the total cost would be:
Total Cost = $44 + 2($23)
2 × 23 = 46
Total Cost = $44 + $46 = $90
The total cost is $90, choice B.

Assume that police estimate that 12% of drivers do not wear their seatbelts. They set up a safety roadblock, stopping cars to check for seatbelt use. They stop 50 cars during the first hour. a. Find the mean, variance, and standard deviation of the number of drivers expected not to be wearing seatbelts. Use the fact that the mean of a geometric distribution is μ= 1 p and
Answer: mean = 8.33, variance =61.11 , standrad deviation = 7.82
Step-by-step explanation:
For geometric distribution,
Mean = [tex]\dfrac1p[/tex]
variance = [tex]\dfrac{1-p}{p^2}[/tex]
Standard deviation[tex]=\sqrt{Variance}[/tex] , where p = probability of success in each trial.
Given: p= 0.12
Mean = [tex]\dfrac1{0.12}=8.33[/tex]
Variance = [tex]\dfrac{1-0.12}{0.12^2}=\dfrac{0.88}{0.0144}=61.11[/tex]
Standard deviation = [tex]\sqrt{61.11}\approx7.82[/tex]
Hence, mean = 8.33, variance =61.11 , standrad deviation = 7.82

Answer:
in the triangle ACB
∠ACB+90+34=180-----> ∠ACB=180-(90+34)----> ∠ACB=56°
∠ACD and ∠ACB-----> are supplementary angles
so
∠ACD+∠ACB=180-----> ∠ACD=180-56----> 124°------> x=124°
the answer Part 1) is x=124°
Part 2)
∠ACB+∠BCF+80=180-----> ∠BCF=180-(∠ACB+80)---> 180-(56+80)
∠BCF=180-136----> 44°-----> y=44°
the answer Part 2) is y=44°

A couple plan s to have children until they get a girl, but they agree that they will not have more than three children even if all are boys. (Assume boys and girls are equally likely.)
a) Create a probability model for the number of children they might have.
b) Find the expected number of children.
c) Find the expected number of boy s they 'll have.
Answer:
b) 1.75 c) 0.875
Step-by-step explanation:
lt is given that a couple plans to have children until they get a girl, but they agree that they will not have more than three children even if all are boys.
a) The possible combination for the number of children that a couple might have :
X 1st girl 1st boy, 2nd girl 1st ,2nd boys,3rd girl 1,2,3rd boys Probability- 0.5 0.25 0.125 0.125
b) Expected number of children :
1(0.5) + 2 ( 0.25 ) + 3 ( 0.125) + 3( 0.125)
= 1+ 0.75
= 1.75
c) Expected number of boys :
0 x 0.5 + 1 x 0.25 + 2 x 0.125 + 3 x 0.125
= 0.875
A manufacturing firm tests job applicants. Test scores are normally distributed with a mean of 500 and a standard deviation of 50. What is the probability that the candidate score is 600 or greater
Answer:
The probability that the candidate score is 600 or greater
P(X≥ 600 ) = 0.0228
Step-by-step explanation:
Step(i):-
Given mean of the Population = 500
Given standard deviation of the Population = 50
Let 'X' be the random variable in normal distribution
Given X = 600
[tex]Z = \frac{x-mean}{S.D} = \frac{600-500}{50} = \frac{100}{50} =2[/tex]
Step(ii):-
The probability that the candidate score is 600 or greater
P(X≥ 600 ) = P(z≥2)
= 0.5 - A(2)
= 0.5 -0.4772
= 0.0228
Final answer:-
The probability that the candidate score is 600 or greater
P(X≥ 600 ) = 0.0228

Tim saw that a pair of $200 dollar jeans had been marked down by 20%. He told his friend that if you took the new price of the jeans and increased that value by 20%, the jeans would return to the original price of $200. is he correct or no?
Hey there!
The answer is no, they would not return to the original price of $200.
This is because when you decrease 200 by 20%, you get 160. Then, if you increase 160 by 20%, you get 192. This is because 20% of 200 and 20% of 160 is different.
Hope this helps! Have a great day, and good luck on your assignment!

What is the solution to the equation 3X + 27 = -2x + 18
Answer:
-9/5 or -1.8
Step-by-step explanation:
3x+27=-2x+18 add 2x to both side
5x+27=18 minus 27 from both side
5x=-9 divide 5
x=-9/5, in decimal form=-1.8
Answer:-9/5
Step-by-step explanation:
3x + 27 = -2x + 18
-27 -27
-3x = -2x - 9
+2x +2x
5x = -9
5x/5 = -9/5
x= -9/5
