you pick random 6,7,8,9 what is P(9)
Step-by-step explanation:
There are a total of 4 numbers to pick.
P(9) means is the probability of you picking the number 9.
Since you are only picking one number, the probability will be 1/4 or 0.25
Gloria, Teresa, and Rebecca went to an office supply store. Gloria bought 8 pencils, 4 markers, and 6 erasers. Her total was
$22.00. Teresa spent $19.25 buying 5 pencils, 7 markers, and 8 erasers. Rebecca bought 5 pencils, 5 markers, and 4
erasers for $15.75. What is the cost of each item?
Are 5x + 9 - 2x = 12 and 3x = 3 equivalent equations
Answer:
Yes
Step-by-step explanation:
If you simplify the 1st equation,
5x + 9 - 2x = 12
Add like terms
3x + 9 = 12
Subtract the 9 from both sides
3x = 3
It gives you the same equation as the other one
Answer:

<a is 34 (half of 68)
<C is 56
triangle YRC is iscocles, YR and RX are both radius, so they are equal. So the base angles must be equal as well. we know that the central angle is 68, because arc YX is 68. to find the measure of angle C use the equation 2x+68=180 (2 of the same angle (x) + 68 makes all the angles in the triangle. 2x=180-68 2x=112x=56Skip E until the end
<G is 84
<G and the angle that is 96 make a linear pair <G + 96=180<G=84Arc YS is 112
Arc YS is = <Rfind <R<R and the angle across from ARC YX are a linear pair<YRX is 68<R+68=180<R is 112<D and F are 42
<D and <F are the base angles of an isosceles triangle (2 sides are the radius again)the central angle in this case is 962x+96=1802x=84x= 42so both D and F are 42now <E is 96
measure of an angle outside the circle with 2 rays touching the circle is the measure of the larger arc of the circle minus the smaller arc divided by 2the measure of the smaller arc is the same as <Gsmaller arc is 84the larger arc is 360-84the larger arc is 276276-84= 192divide by 2 to get <E192/2=96Can someone help me?

Beginning at 8:30 A.M., tours of the National Capitol and
the White House begin at a tour agency. Tours for the
National Capitol leave every 15 minutes. Tours for the
White House leave every 20 minutes.
a) How often do the tours leave at the same time?
b) When is the next time the two tours will leave at
the same time?
Answer:
Step-by-step explanation:
if both tours start at 8:30 A.M, the NC (National Capitol) 8:45, and the WH (White House) leaves at 8:50.
NC
08:45 08:50
09:00 09:10

The sum of N and the product 5 times n is 24. What is the value of n?
Answer: n = 4
Step-by-step explanation:
We will first write a mathematical equation to represent the situation. Then, we will solve it.
The sum of n → Sum means addition, so "n +"
product of 5 times n → Product and times means multiplication, so "5n"
is 24 → Is represents equals, so "= 24"
The sum of N and the product 5 times n is 24 → n + 5n = 24
Now that we have our equation, we can solve. We will do this by adding n and 5n, then dividing both sides of the equation by 6.
n + 5n = 24
6n = 24
n = 4
A special CPI is constructed to measure the variation of these products, so that coffee and bread have a weight of 0.35 of the total and egg, ham and cheese 0.1 of the total. variation of the CPI?
9514 1404 393
Answer:
The CPI increased 3.42% in Month 2.
Step-by-step explanation:
In a spreadsheet, the weighted sum is easily computed using the SUMPRODUCT( ) function. It multiplies the corresponding values of two arrays, then returns the sum of those products. If one of the values is a weight, then the result is a weighted sum.
Your CPI is computed as the weighted sum of the prices of the individual products. The percentage change is computed in the usual way:
pct change = ((new value)/(old value) -1) × 100%
Of course, the spreadsheet can format a fraction as a percentage, so the computation of the change can stop after 1 is subtracted from the ratio.
In a survey of 12 people, it was found that an average of $36 was spent on their child's last birthday gift with a standard deviation of $11. Estimate the mean amount people spend on their child's last birthday gift with 80% confidence using the appropriate critical value to three decimal places. Enter your answer as equations or as numbers rounded to four decimal places.
Answer:
(27.3692 ; 44.6308)
Step-by-step explanation:
Mean, xbar = 36
Standard deviation, s = 11
Sample size, n = 12
Tcritical at 0.2, df = 12 - 1 = 11 ; Tcritical = 2.718
Confidence interval :
Xbar ± Margin of error
Margin of Error = Tcritical * s/sqrt(n)
Margin of Error = 2.718 * 11/sqrt(12) = 8.6308
Confidence interval :
Lower boundary : 36 - 8.6308 = 27.3692
Upper boundary : 36 + 8.6308 = 44.6308
(27.3692 ; 44.6308)

Step-by-step explanation:
A science test, which is worth 100 points, consists of 24 questions. Each question is worth either 3 points or 5 points. If x is the number of 3-point questions and y is the number of 5-point questions, the system shown represents this situation. x + y = 24 3x + 5y = 100 What does the solution of this system indicate about the questions on the test? The test contains 4 three-point questions and 20 five-point questions. The test contains 10 three-point questions and 14 five-point questions. The test contains 14 three-point questions and 10 five-point questions. The test contains 20 three-point questions and 8 five-point questions.
Answer:
Step-by-step explanation:
Solve the system of equations
x + y = 24 both sides times 3 3x + 3y = 72
3x + 5y = 100
3x + 3y = 72 subtract the bottom equation from the top one
0x + 2y = 28
y = 14 five point questions 70 points
x + 14 = 24 the first equation with y set to 14
x = 10 three point questions 30 points

Answer:
the mean is 40 degrees celcius
standar deviaton is 1.11 degrees Celsius
Step-by-step explanation
khan academy
The temperature values of the participants in celcius are :
Mean = 40°CStandard deviation = - 16.67°CInformation about body temperature :
Mean = 104°F
Standard deviation = 2°F
To convert to Celsius temperature :
°C = 5/9(°F - 32)
To temperature values in °C :
Mean temperature :
°C = 5/9(104 - 32)
°C = 40°C
Standard deviation of temperature :
°C = 5/9(2 - 32)
°C = - 16.67°C
Hence, the temperature values in Celcius are : 40°C and - 16.67°C

2. Use the distributive property to write an expression that is equivalent to 12 + 4x.
Answer:
4(x+3)
Step-by-step explanation:
So with the distrubutive property, you look at the numbers you have, and then take the greatest common factor between the two.
So lets think about it, what goes into both 12 and 4?
2 does, but is that the greatest common factor? No.
What about 4? That goes into 12 and 4. Is it the greatest common factor? Yup it is.
So, what do we get when we take 4 from 4x? We get 1x, or just x.
How about 12? Well, when we take 4 from 12, we get 3.
Now, lets take the common greatest factor, and our two new numbers and put them back into the expression.
Remember that the greatest common factor, the one you took from the other numbers, is what goes first:
4()
Remember to put the parethese there, or else you would only be multiplying the first number by 4, and not the second.
Next lets put the other numbers in. In most expressions, you should put the x number in first, and the normal number in second. So it should now be:
4(x+3)
This is your expression.
Hope this helps! ;)

Answer:
4(3 +x)

Answer:
3.13π
Step-by-step explanation:
One plane is a quarter of a semi-circle, since the semi-circle is split into four equal parts. One quarter of a semicircle is one eighth of a circle, so find the are of a circle with diameter 10ft, and divide by 8:
Diameter is half the radius, so the radius is 5ft.
Area of a circle = π(radius)²
=5²π
=25π.
We're looking for an eigth of the circles area so: 25π/8 = 3.125π≈3.13π
