Answer:
4!
Step-by-step explanation:
40 x 4 = 160
160+ 140 = 300
Answer:
4 dresses
Step-by-step explanation:
If she starts with $300 and ends up with $140, that means that she spent $160. So, since each dress costs $40, you divided $160 by $40, which equals 4. So Michelle bought 4 dresses.

Write an equation of a line passing through (-8, 6) and parallel to the line y=-4x - 1
The line is parallel so it has the same slope as the other line, -4.
Substitute the x and y variables with the given points and find the y-intercept.
(-8, 6)
y = -4x + b
6 = -4(8) + b
6 = -32 + b
6 + 32 = b
38 = b
So the equation is:
y = -4 + 38
The line is parallel so it has the same slope as the other line, -4.
Substitute the x and y variables with the given points and find the y-intercept.
We have given that,
An equation of a line passing through (-8, 6) and parallel to the line y=-4x - 1
(-8, 6)
What is the slope-intercept form?
y=mx+b
Where m is the slope
y = -4x + b
6 = -4(8) + b
6 = -32 + b
6 + 32 = b
38 = b
So the equation is y = -4 + 38.

Find the Measure of angle O
(see image)
Only real answers, please
Answer:
From the given figure we can see that :---
MN||PO, MN=PO and MP=NO
Therefore, angle M=angle N (adjacent sides of the trapezoid)
[tex](8x - 16) = (6x + 20) \\ 2x = 36 \\ \boxed{x = 18}[/tex]
angle M=angle N= (6×18)+20=108+20 =128°
angle O =(180°-128°)=52°
Hence, angle O is 52°.Tina is tossing bean bags at a target. She hit the target on 3 out of her last 15 tries. Considering this data, how many hits would you expect Tina to get during her next 10 tosses?
Answer:
2
Step-by-step explanation:
Because 1 in 5 throws she get 1 in
Answer: We are given 3 out of 15, the best is to convert into a percent, [tex]\frac{3}{15}[/tex] is our fraction, now divide the numerator by the denominator 3÷15=.0.20. Now bump it up two digits, 20%. Now 20% of 15 is 3, we need to find 20% of 10, if 20% is 20 from 100, then 2 must be 20% of 10.
And your answer is 2 out of 10 tosses.

The power of 2 in 400! is 397.
What is the method of determination of power of prime in Factorial ?Let p is the prime number whose power is to be found
Let n is the factorial number then
p in n! = (n /p) + (n/p²) +(n/p³) + .......
until Numerator < Denominator
and after division only the integer part is taken
Therefore to determine the power of 2 in 400!
2 in 400! = (400 /2) + ( 400 /2²) + (400 /2³) +(400 /2⁴) +(400 /2⁵) +(400 /2⁶) +(400 /2⁷) +(400 /2⁸) + above this N < D
2 in 400! = 200 +100 +50+25+12+6+3+1
2 in 400 = 397
Therefore the power of 2 in 400! is 397.

Step-by-step explanation:
The mayor of a town has proposed a plan for the construction of a new community. A political study took a sample of 1300 voters in the town and found that 45% of the residents favored construction. Using the data, a political strategist wants to test the claim that the percentage of residents who favor construction is more than 42%. Testing at the 0.02 level, is there enough evidence to support the strategist's claim?
Answer:
We reject H₀ , we found enough evidence to support the claim
Step-by-step explanation:
Sample size n = 1300
Sample proportion p = 45 % p = 0,45 and q = 0,55
Proportion of population p₀ = 42 % p₀ = 0,42
Hypothesis Test
Null Hypothesis H₀ p = 0,42
Alternative Hypothesis Hₐ P > 0,42
A one-tail test to the right is needed to evaluate the claim
Sample size big enough to consider binomial distribution can approximate to normal distribution
1300*p > 10 1300*q > 10
Significance level α = 0,02
z(c) fom z-table is z(c) = 2,05
To compute
z(s) = ( p - p₀ ) /√ (p*q)/n
z(s) = ( 0,45 - 0,42 ) /√ (0,45*0,55)1300
z(s) = 0,03 / 0,014
z(s) = 2,14
Comparing z(c) and z(s) z(s) > z(c) then z(s) s in the rejection region we must reject H₀ we found enough evidence to spport the claim

Factor the equation below.
f(x) = x2 + x - 20
Answer:
f(x) = (x+5)(x-4)
Step-by-step explanation:
Key skills used in this problem: Quadratic equations, factoring
1) The equation x^2 + x - 20 is factorable (meaning it can be facttored easily)
2) We need to find factors of -20 that add up to 1. This is because our ac (a term times the c term) is -20 and our b term (the coefficient for +x) is 1.
3) The two factors would be 5 and -4.
4) So it would be (x + 5)(x - 4) when factored
Hope you understood and have a nice day!! :D
Answer:
f(x)= (x+5)(x-4)
Step-by-step explanation:
First muliply the coefficient of the xsquared with the constant, in this case 1 × -20 = -20. Then figure out two factors of -20 that equal the coefficient of the stand-alone x when added together. In this case, that coefficient is 1. Factors of -20 that add to 1 are 5 and -4. Now simply take each of those numbers and shove them into parenthesis with an x.
