Spinner Results
Color Frequency
Red 4
Blue 3
Green 2
Yellow 2
Purple 6
Based on these results, express the probability that the next spin will land on blue as a fraction in simplest form.
Step-by-step explanation:
so, we had
4+3+2+2+6 = 17 experiments
I assume the spinner has 5 equality sized fields with different colors.
so, normally we would assume that in average each color has the same probability : 1/5 (desired results over totally possible results).
the experiments with the actual spinner give us now observational data and probabilities.
after all, a spinner (as a die, or a roulette wheel, or ...) can have slightly different probabilities for the individual outcomes based on design and manufacturing.
so, based on these results we see the actual probabilities like this
red 4/17
blue 3/17
green 2/17
yellow 2/17
purple 6/17
so, the observed probability shows us a probability of blue in the next spin to be 3/17.
please note, that after that next (18th) spin all the observed probabilities have to be updated depending on the actual result.
so, if the result of spin 18 is indeed blue, the probabilities for spin 19 would change to
red 4/18
blue 4/18
green 2/18
yellow 2/18
purple 6/18
2(x-6) + 6 = 4x - 4
Find X
Step by step explanation:
Step 1:
[tex]2(x-6) + 6 = 4x - 4[/tex]
Step 2:
[tex]⇒2x - 12 + 6 = 4x - 4[/tex]
Step 3:
[tex]⇒2x - 6 = 4x - 4[/tex]
Step 4:
[tex]⇒ - 6 + 4 = 4x - 2x[/tex]
Step 5:
[tex]⇒2x = - 2[/tex]
Step 6:
[tex]⇒x = \dfrac{ - 2}{2} [/tex]
Step 7:
[tex]⇒x = - 1✓[/tex]
[tex]◈verification◈[/tex]
Step 1:
[tex]2( - 1-6) + 6 = 4( - 1) - 4[/tex]
Step 2:
[tex]⇒2( - 7) + 6 = - 4 - 4[/tex]
Step 3:
[tex]⇒ - 14 + 6 = - 8[/tex]
Step 4:

The sum of 19 and a number x is equal to 22
Answer:
x = 3
Step-by-step explanation:
19+1=20
19+2=21
19+3=22
Or you can subtract 22 and 19 to find x

Solve this inequality. 9p < -81
A.
p > 90
B.
p < -9
C.
p < -90
D.
p < 72
Answer:
B. p < -9
Step-by-step explanation:
Given inequality:
[tex]9p < -81[/tex]
divide both sides by 9:
[tex]\implies \dfrac{9p}{9} < -\dfrac{81}{9}[/tex]
[tex]\implies p < -9[/tex]
The equation 8m+3=75 models how many months, m, it takes a tree to reach a height of 75 inches after being potted. If the tree grows the same number of inches each month, how many months does it take the tree to reach a height of 75 inches?
A.72 months
B.25 months
C.9 months
D.8 months
Answer:
9 months
Step-by-step explanation:
8m + 3 = 75
-3 -3
8m = 72
/8 /8
m = 9
In 9 months the tree will be 75 inches tall
A city's bus system has a red-line and a blue-line. Both a red-line bus and a blue-line bus are currently at the City Hall Station. If a red-line bus arrives at the City Hall Station every 12 minutes and a blue-line bus arrives at the City Hall Station every 10 minutes, after how many minutes will the two buses next arrive at the City Hall Station at the same time?
Answer:
5.45minutesStep-by-step explanation:
Given that the arrival time of the redline bus= 12minutes
arrival rate = 1/12 arrival per minutes
arrival time of the blueline bus= 10minutes
arrival rate = 1/10 arrival per minutes
the combined arrival rate is given by the expression
let redline be A
and blueline be B
and let the combines arrival rate be x
A+B/(A*B)=1/x
1/12+1/0=1/x
12+10/12*10=1/x
22/120=1/x
x=120/22
x=5.45minutes
Which is a factor of 144 − 49x2? 12 - 7x2 72 – 7x2 12 – 7x 72 7x.
The factors of the given expression [tex]144-49x^{2}[/tex] will be [tex](7x+12)(7x-12)[/tex]
What will be the factors of the given equation?It is given that
[tex]144-49x^{2}[/tex]
Now by simplifying it
[tex](12)^{2} -(7x)^{2}[/tex]
Now from the formula, we know
[tex]a^{2} -b^{2} = (a+b)(a-b)[/tex]
So it will become
[tex](12)^{2} -(7x)^{2}= (12-7x)(12+7x)[/tex]
Thus the factors of the given expression [tex]144-49x^{2}[/tex] will be (7x+12)(7x-12)

Which 3-D figure matches the surface area formula?
Figure A
Figure B
Figure C
Figure D
Answer:
D
Step-by-step explanation:
you mean the formula is 4×pi×r² (not 4×pi/r²), right ?
then the correct answer is the sphere (ball).
the surface area of a cylinder is
top and bottom circle area = pi×r² each = 2×pi×r² both
and the mantle is 2×pi×r×height
the surface area of a block has nothing to do with pi.
it is the sum of 6 rectangles.
the surface area of a cone is
A = πr(r + sqrt(h² + r²))
again, also depending on "hight"
