Answer:
63%
Step-by-step explanation:
A white marble was selected 41 out of 65 times, making the probability of getting white 41/65.
To convert this to percent, divide 41 by 65, then multiply by 100%.
41/65 = 0.630769 = 63% (rounded)
What is 65% out of 45?

Step-by-step explanation:
Is the statement [x]=Lx + 1)
true for all real
numbers? Explain.
The Edg answer is as follows -
The statement is not true for all real numbers. It is only true for decimal or fractional values of x .
If x is an integer, then the ceiling function returns x when the input is x . But, the flooring function returns x + 1 when the input is x + 1.
Since x does not equal x + 1 when x is an integer, the expressions are not equal when x is an integer.

√128ab^3
simplify square roots
Answer:
[tex]8b\sqrt{2ab}[/tex]
Step-by-step explanation:
Rewrite 128a[tex]b^{3}[/tex] as [tex](8b)^{2}[/tex] ⋅ (2ab).
Factor 64 out of 128.
[tex]\sqrt{64 (2)ab^{3} }[/tex]
Rewrite 64 as [tex]8^{2}[/tex] .
[tex]\sqrt{8^{2} . 2ab^{3}[/tex]
Factor out [tex]b^{2}[/tex].
[tex]\sqrt{8^{2} . 2a (b^{2}b)[/tex]
Move a.
[tex]\sqrt{8^{2} . 2b^{2}ab[/tex]
Move 2.
[tex]\sqrt{8^2b^2 . 2ab}[/tex]
Rewrite [tex]8^{2} b^{2}[/tex] as [tex](8b)^{2}[/tex].
[tex]\sqrt{(8b)^2 . 2 (ab)}[/tex]
Add parentheses.
[tex]\sqrt{(8b)^2 . (2ab)}[/tex]
Pull terms out from under the radical.
[tex]8b\sqrt{2ab}[/tex]
Army needs to order a shade for a triangle-shaped window has a base of 6 feet and a height of 4 feet.what is the area of the shade
Answer:
The area of the shade is 12 feet
Step-by-step explanation:
To find the area you would do 6 * 4 which equals 24 but with every triangle you have to cut the area in half so the actual answer would be 12 feet
All TVs are on sale at Target for 25% off.
The sales tax in Rochester is 7.875%
If Mrs. Winters wants to buy a TV that is regularly priced $800, what will her final cost be?
Answer:
$647.25
Step-by-step explanation:
Twenty-five percent off the regular $800 price comes to 0.75($800), or $600 (after the discount).
Calculating the 7.875% sales tax and adding it in, we find that the final price to be paid is (1 + .07875)($600), or $647.25.
The probability distribution for a random variable x is given in the table. -5 -3 -2 0 2 3 Probability .17 .13 33 16 11 10 Find the probability that x < 0
Answer:
0.79
Step-by-step explanation:
add up the probability that is less than or equal to 0, which is 0.17+0.13+0.33+0.16 = 0.79
The probability [tex]$x \leq0$[/tex]. is 0.79.
What is probability distribution?
A probability distribution exists a statistical function that defines all the possible values and likelihoods that a random variable can consider within a provided range.
The probability distribution is given in the table.
Probability that [tex]$x \leq0[/tex]
The values that are 0 or lower are -3, -2 and -5. So
[tex]$P(X \leq0)=P(X=-3)+P(X=-2)$$[/tex]
From the table:
[tex]$&P(X=-3)=0.13, P(X=-5)=0.17, P(X=-2)=0.33[/tex] and [tex]P(X=0)=0.16[/tex]
So, [tex]$&P(X \leq-3)=P(X=0)+ P(X=-3)+P(X=-5)+P(X=-2)[/tex]
= 0.16 + 0.13 + 0.17 + 0.33
= 0.79
0.79 probability that [tex]$x \leq0$[/tex].

482.56/8 = $60.32
How can you tell if these are greatest common factor or difference of squares questions?
Answer:
When an expression can be viewed as the difference of two perfect squares, i.e. a²-b², then we can factor it as (a+b)(a-b). For example, x²-25 can be factored as (x+5)(x-5). This method is based on the pattern (a+b)(a-b)=a²-b², which can be verified by expanding the parentheses in (a+b)(a-b).

It's asking you what the probablitiy of a red car is.
Since this looks like a test/homework, I'll give some hints.
Let's say that SUV's and car's are x.
Out of x, 60 percent is cars.
Let's call the amount of cars we have y.
Out of y amount car's, 15 percent is red.
It's asking that if you randomely chose a car, what the probability would be if you got a non-red car.
Of course, this problem only needs one variable, but for the sake of simplicity, I added 2.

Answer:
x = 3.2
Step-by-step explanation:
Apply pythagorean theorem, c² = a² + b²
Where,
c is the hypotenuse/longest side = √(10² - 9²) ≈ 4.4
a = x
b = 3
Substitute
4.4² = x² + 3²
19.36 = x² + 9
x² = 19.36 - 9
x² = 10.36
x = √10.36
x = 3.2 (nearest tenth)

Kelly drove 385 miles to visit her friend. She drove at an average rate of 55 miles per hour.
How long did it take her to drive to her friend's house?
A: 5 hours
B: 7 hours
C: 9 hours
D: 11 hours
Answer:
B. 7 hours
Step-by-step explanation:
The formula for time (in this scenario) is t = d/s.
t - time
d - distance
s - speed
For this problem, d - 385 mi and s - 55 mph. To find the time this trip took, you would solve 385/55=7. In the end, Kelly drove for 7 hrs. Hope this helps!!

Step-by-step explanation:
It would not be 1 or 8, because 8 + 8 + 8 + 4 = 28, and 1 + 1 + 1 + 4 = 7, so that leaves 3/8 and 8/3. To figure out which one it would be, you'd do 3/8(3) + 4, which equals 5.125 or 41/8. If you did 8/3, however, it'd equal 12.
