Answer:
I understand there is a typo, so Belly and Billy are the same person. His age is represented as B, and Suzy's as S.
S = 19
B = 9
Step-by-step explanation:
Suzy is ten years older than Belly:
(1) S = B + 10
the next year she will be twice as old as Billy
(2) S + 1 = 2 (B + 1)
solving the system of equation (1) and (2):
Making (2) - (1):
1 = 2 (B + 1) - B - 10 => 1 = 2 B + 2 - B - 10 => 1 = B - 8 => B = 9
replacing in (1) S = 19
If P(A or B) = 0.8, P(A) = 0.3, and P(A and B)= 0.15, find P(B).
P(B) =
(Simplify your answer. Type an integer or a decimal.)
9514 1404 393
Answer:
P(B) = 0.65
Step-by-step explanation:
The appropriate formula is ...
P(A or B) = P(A) +P(B) -P(A and B)
Then P(B) is ...
P(B) = P(A or B) +P(A and B) -P(A)
P(B) = 0.8 +0.15 -0.3
P(B) = 0.65

The clothing store marked down all their shirts by 30%. If a shirt originally cost $24, what is the sale price of the shirt?
Answer:
$16.80
Step-by-step explanation:
Since the shirts are marked down by 30%, you need to multiply the cost of the shirt by the percentage.
$24 × 0.3 = $7.20
Next, subtract the discount from the original price to find the discounted price.
$24 - $7.20 = $16.80

Answer:
[tex] x=27\degree[/tex]
Step-by-step explanation:
[tex] \because AC || DE.... (given) [/tex]
[tex] \therefore m\angle CAD= m\angle EDF\\ (corresponding \: \angle s) [/tex]
[tex] \therefore m\angle BAD= m\angle EDF\\(\because B\in \overleftrightarrow{AC}) [/tex]
[tex] \therefore m\angle BAD= 2x\\(\because m\angle EDF=2x) [/tex]
[tex] In\:\triangle BAD, [/tex]
[tex] m\angle BAD+m\angle BDA+m\angle ABD= 180\degree [/tex]
[tex] 2x+2x+72\degree = 180\degree [/tex]
[tex] 4x= 180\degree -72\degree [/tex]
[tex] 4x= 108\degree [/tex]
[tex] x= \frac {108\degree}{4}[/tex]
[tex] x=27\degree[/tex]
A regression model to predict Y, the state-by-state 2005 burglary crime rate per 100,000 people, used the following four state predictors: X1 5 median age in 2005, X2 5 number of 2005 bank- ruptcies per 1,000 people, X3 5 2004 federal expenditures per capita, and X4 5 2005 high school graduation percentage. (a) Write the fitted regression equation. (b) Interpret each coef- ficient. (c) Would the intercept seem to have meaning in this regression

In the first 1/5 hour of a snowstorm 1/3 inches of snow fell in the snow continues at the same rate how much snow will fall in 4 1/5 hours
Answer:
70 (I think)
Step-by-step explanation:
1/3 is 3.33 (threes go on forever) but thats only for 1/5 of an hour, so you multiply 3.33 by 5 and get 16.66 (pretty sure the sixes also go on forever) and thats one full hour, so you multiply 16.66 by 4.20 (4 1/5 but in decimal form) and you get 70

Step-by-step explanation:
Identify the set of numbers that makes up the domain in the relation ((-2,-2), (0, 2), (2, 4), (3, -6)).
0-2.0.2.3
0-2.0.3,4
0-6-2, 0.2.3.4
0-6-2, 2.4
Answer:
The first set, -2,0,2,3 are the domains of this relation.
Answer:
The correct answer is:
Option 1: -2,0,2,3
Step-by-step explanation:
When a relation is written in the form of ordered pairs.
In each ordered pair, the first element/coordinate is the input of the function and the second element//coordinate of ordered pair is the output.
The set of inputs is the domain of the relation.
Given relation is:
((-2,-2), (0, 2), (2, 4), (3, -6)).
The first element of each ordered pair is:
-2, 0, 2, 3
Hence,
The correct answer is:
Option 1: -2,0,2,3

Expand and simplify
2(4x + 3) + 4(3x - 1)
[tex]2(4x + 3) + 4(3x - 1)[/tex]
[tex] = (8x + 6) + (12x - 4)[/tex]
[tex] = 8x + 6 + 12x - 4[/tex]
[tex] = (8x + 12x) + (6 - 4)[/tex]
[tex] = 20x + 2[/tex]
Answer:
8x+6+12x-4= 0
20x+2= 0
20x=-2
