Jackie has a choice of 3 pairs of shoes, 3 pants, and 4 shirts that can make an outfit for today. Each pair of shoes has a different heel height, each pair of pants is made from a different fabric, and each shirt is a different color.
Jackie randomly picks some clothes.
What is the probability that she chooses an outfit consisting of the flat heel or spike heel shoes, the twill or the denim pants, and the white or black shirt?
2/13+2/13+2/13
= 6/13
Step-by-step explanation:
The probability that she chooses an outfit consisting of the flat heel or spike heel shoes, the twill or the denim pants, and the white or black shirt is given by P ( A ) = 22.22 %
What is Probability?The probability that an event will occur is measured by the ratio of favorable examples to the total number of situations possible
Probability = number of desirable outcomes / total number of possible outcomes
The value of probability lies between 0 and 1
Given data ,
Jackie has a choice of 3 pairs of shoes, 3 pants, and 4 shirts that can make an outfit for today.
Each pair of shoes has a different heel height, each pair of pants is made from a different fabric, and each shirt is a different color.
So , There are a total of 3 x 3 x 4 = 36 possible outfits.
The number of outfits with the specified choices is:
2 (choices of shoes) x 2 (choices of pants) x 2 (choices of shirts) = 8
Therefore, the probability that Jackie chooses an outfit consisting of the specified choices is:
8 / 36 = 2 / 9 ≈ 0.2222 or about 22.22%
Hence , the probability is P ( A ) = 22.22 %

Based on this sample, how many of the quarters in the full bag were likely tobe eagle quartersWe can conclude from the given data that the ratio of the Eagle and state quarters is 4:6 or 2:3 suppose the common factor is a so the value will be calculated as:-
E + S = 500
2a + 3a = 500
5a = 500
a = 100
E = 2a
E = 2 x 100 = 200

Mindy deposits $250 into a savings account that pays simple interest. If the interest rate is 1.5%, what is her account balance at the end of a 2 years if she makes no withdrawals?
Answer:
Her account balance at the end of 2 years is $257.5.
Step-by-step explanation:
This is a simple interest problem.
The simple interest formula is given by:
[tex]E = P*I*t[/tex]
In which E is the amount of interest earned, P is the principal(the initial amount of money), I is the interest rate(yearly, as a decimal) and t is the time.
After t years, the total amount of money is:
[tex]T = E + P[/tex]
In this question:
Deposit of $250, so [tex]P = 250[/tex]
Interest rate of 1.5%, so [tex]I = 0.015[/tex]
2 years, so [tex]t = 2[/tex]
Amount of interest earned:
[tex]E = P*I*t = 250*0.015*2 = 7.5[/tex]
Total amount:
[tex]T = E + P = 7.5 + 250 = 257.5[/tex]
Her account balance at the end of 2 years is $257.5.

find the total surface area of a right cone with a base diameter of 10cm and a height of 12cm. give your answer in terms of pie.
Answer:
The total surface area is 90π cm²
Step-by-step explanation:
To find the total surface area of his cone, we will follow the steps below;
write the formula for finding the total surface area of a cone
Total surface area = πrl + πr²
where r is the radius and l is the slant height
from the question, diameter = 10 cm, diameter = 2r this implies that r = d/2 = 10/2 = 5 cm
Also from the question given to us, height h = 12 cm, but what we want is slant height l. We can find this by using the Pythagoras theorem to find the slant height using the height giving to us and the radius.
opposite² + adjacent² = hypotenuse²
where radius is the adjacent, height is the opposite and the slant height is the hypotenuse
5² + 12² = l²
25 + 144 = l²
169 = l²
13 = l
l= 13 cm
hence slant height =13 cm
We can now proceed to insert the values into the formula
Total surface area = πrl + πr²
= π×5×13 + π×5²
=65π + 25π
=90π cm²
The total surface area is 90π cm²

A rectangle is sometimes, always, never similar to another rectangle
Two rectangles can be similar, but that's not always guaranteed.
In fact, similar shapes have the same angles and correspondant sides in proportion.
All rectangles will always have four right angles, so we only have to worry about the sides.
Let [tex]a,b[/tex] be the sides of a rectangle, with [tex]a\leq b[/tex]. Let [tex]c,d[/tex] be the sides of a rectangle, with [tex]c\leq d[/tex].
Then, the two rectangles are similar if and only if
[tex]a\div c=b\div d[/tex]
So, for examples, a rectangle with dimensions 3 and 7 is similar to a rectangle with sides 6 and 14 (both sides have been doubled), but it's not similar to a rectangle with sides 6 and 21 (one side has been doubled, the other has been tripled).

solve 25+8m =73 M=....
Answer:
25+8m=73
We move all terms to the left:
25+8m-(73)=0
We add all the numbers together, and all the variables
8m-48=0
We move all terms containing m to the left, all other terms to the right
8m=48
m=48/8
m=6
Answer:
[tex]m = 6[/tex]
Step-by-step explanation:
[tex]25 + 8m = 73 \\ 8m = 73 - 25 \\ 8m = 48 \\ \frac{8m}{8} = \frac{48}{8} \\ m = 6[/tex]

How many times larger is the volume of a sphere if the radius is multiplied by 5?
Answer:
Brainliest please
The Volume is 125 times bigger.
Step-by-step explanation:
V = [tex]\frac{4}{3}*\pi *r^{3}\\[/tex] is the normal formula.
If you multiply the radius by 5 the it changes to
V = [tex]\frac{4}{3}*\pi *(5r)^{3}[/tex]
And when you simplify you get
V = [tex]\frac{4}{3} * \pi * 125r^3[/tex]
And the only difference between the inital equation and this one is *125 and so the volume is 125 bigger if the radius is multiplied by 5.

My grandson is about as many days as my son in weeks, and my grandson is as many months as I am in years. My grandson, my son and I together are 120 years. Can you tell me my age in years ?
Answer:
72
Step-by-step explanation:
Let m be the age in years. If s is the son's age in years, then the son is 52x weeks old. If g is the grandson's age in years, then the will be grandson 365m days old. So.... the labels are for the equation.
365m = 52x.
Since the grandson is 12w months old,
12w = months.
Since the grandson, son and the person together are 120 years,
m + x + months = 120.
these are the labels (m, x, and month)
month = 624 x 120 / 1041 = 72.
So, I am basically 72 years old.
hope this helped :D
