Step-by-step explanation:
31.2×4/3
12a+8 = 41.6
12a=33.6
a= 2.8
Answer:
answer is 2.8
Step-by-step explanation:
3/4=0.75
0.75x12=9
0.75x8=6
9a+6=31.2
subtract 6 from both sides
9a=25.2
divide both sides by 9
a=2.8

An experiment consists of randomly selecting a marble from a bag, not replacing it, and then selecting another marble. The bag contains 3 yellow marbles and 2 white marbles. What is the probability of selecting a white marble and then a yellow marble?
Answer:
The bag contains 4 blue marbles, 3 green marbles, 7 red marbles, and 1 yellow marble. What is the probability of selecting a red marble and then a blue marble? Question 3 ... 4 blue marbles+ 3 green marbles+ 7 red marbles+ 1 yellow marble= 15 ... P(red,blue0 = 7/15 * 2/7 = 2/15 =.13333333 = 13.33%.
Step-by-step explanation:
Answer:
There are 14 total marbles. The probability of drawing a yellow marble on the first draw is 3/14. Given replacement, the probability on the second draw is the same as on the first draw, so the probability of a black marble on the second draw is 6/14. The probability of drawing first a yellow marble then a black marble is 3/14 * 6/14 = 18/196.

Hi, if you could help that would be great :)
Answer:
Similar
Step-by-step explanation:
12/7.2 =1.66666666 Use ratios to determine if they are similar using SSS similarity.
18/10.8 =1.6666666
10/6 =1.666666666 They are similar b/c all the sides are proportional to one another.
Answer:
Similar
Step-by-step explanation:
each of the sides are proportionate
on 5x (2 + 1)2 : 3 =
Step 1 Add 2 to both sides.
5x=3+2
Step 2 Simplify 3+23+2 to 55.
5x=5
Step 3 Divide both sides by 5.
x=1

14a)
(B) Predict the ticket sales if the tickets are $8 each.
14b)
(C) What would the price of the ticket have been if there
is $1000 in ticket sales?
14c)
Answer:
1500.110 - 0.157x - 5.853x² ;
1124.262
Step-by-step explanation:
Given the data:
Price __ Sales
3 ____1447
5 ___ 1353
7 ____ 1212
9 ____1025
11 ____790
13 ____509
Usibg the quadratic regression calculator :
1500.110 - 0.157x - 5.853x²
If ticket price = $8 each
Ticket sales will be :
y = 1500.110 - 0.157(8)- 5.853(8^2)
= 1124.262
26 out of 65 as a percentage
How would you do that without a calculator?
Answer:
40%
Step-by-step explanation:
you would first simply the fraction down
13 goes into both numbers so the fraction can be simplified to
2/5 which is think is simply enough to know that 2/5 is 40% but if not the explanation would be
100÷5 =20
20 x by the 2 from the fraction
= 40%
Step-by-step explanation:
65 = 100%
0.65 = 1%
26 = x%
x = (26 ÷ 0.65)%
x = 40%
--------------------------FOLLOW MEwhat is the area of the shaded region?
Answer:
ft25x25ft footjob is great
Step-by-step explanation:
tags:asuna zero two
That area is the square is 25 x 25 = 625
The circle touches the square so the diameter of the circle is 25.
Area of the circle = pi x r ^2 where r is half the diameter.
Area of circle = 3.14 x 12.5^2 = 490.625
The area of the shaded region is the area of the square - area of the circle:
625 - 490.625 = 134.375 square feet.

Inequality
Answer:
the answer to the inequality is
Step-by-step explanation:
x = 3
Answer:
[tex]x < 4[/tex]
Step-by-step explanation:
1) Subtract 2 from both sides.
[tex]5x < 22 - 2[/tex]
2) Simplify 22 - 2 to 22.
[tex]5x < 20[/tex]
3) Divide both sides by 5.
[tex]x < \frac{20}{5} [/tex]
4) Simplify 20/5 to 4.
[tex]x < 4[/tex]
So, therefor, the answer is, x < 4.

How do I write an equation for a line with a slope of ²/³ that has a y-intercept at -2.Titer eat at 2
Answer:
y = 2/3x - 2
Step-by-step explanation:
Given :
Slope, b = 2/3
y - intercept, c = - 2
The equation of a line can be expressed in slope intercept form as :
y = bx + c
b = slope ; c = y - intercept
Hence, line equation becomes ;
y = 2/3x - 2
