For each diagram below, write and solve an equation.

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

growth whose rate becomes ever more rapid in proportion to the growing total number or size.

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"

Answer:

106 degrees

Step-by-step explanation:

1. Supplementary angles add up to 180.  So subtract 74 from 180 to find the measure of angle C.

2. The full square isn't visible to answer.

1. m∠C = 106°

If angle A and angle C are supplementary, then the sum of their measures is 180°. Thus:

m∠A + m∠C = 180°

74° + m∠C = 180°

m∠C = 180° - 74°

m∠C = 106°

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]

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:

[tex]⇒ - 8 = - 8[/tex]

Answer:

Step-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

The factors of the given expression [tex]144-49x^{2}[/tex] will be  [tex](7x+12)(7x-12)[/tex]

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)

i did the math QUIZ 8th grade EDG

Answer: No. Collin was wrong.

Step-by-step explanation:

From the question, we are informed that the answer that Collin had on his paper was −13 − (15 + 58) and the correct answer, located in the back of the book, was −13 −15 + 58.

Collin is wrong because he didn't take into cognisance the effect of minus on the bracket. Here, −13 − (15 + 58) will be equal to -13 -15 -18. This is because minus multiplied by plus equals to minus. He shouldn't have put the numbers in the bracket.
