Answer:

$P(Blue)=0.60$

Step-by-step explanation:

Probability: $Probability\ of\ an\ event=\frac{favourable\ outcome}{total\ outcome}$

$Total\ marbles=20\\\\Hence\ total\ outcomes=20\\\\Blue\ marbles=12\\\\Hence\ favourable\ outcomes=12\\\\P(Blue)=\frac{12}{20}\\\\P(Blue)=\frac{2\times 6}{2\times 10}\\\\P(Blue)=\frac{6}{10}\\\\P(Blue)=0.60$

Yan is climbing down a ladder. Each time he descends four rungs on the ladder, he stops to see how much farther he has to go

anastassius [24]

Question:

Yan is climbing down a ladder. Each time he descends 4 rungs on the ladder, he stopped to see how much farther he has to go. If Yan made eight stops with no extra steps, which expression best shows another way to write the product of the number of ladder rungs that Yan and climbed?

4+4+4+4

8+8+8+8

(-1)(4+4+4+4)

(-8) + (-8) + (-8) + (-8)

Answer:

$Total = (-8) +(-8) +(-8) +(-8)$

Step-by-step explanation:

Given

$Rungs = -4$ --- It is negative because he is climbing down

$Steps = 8$

Required

An expression for the number of rungs climbed

To do this, we simply multiply the number of rungs by the steps taken.

$Total = Rungs * Steps$

$Total = -4 * 8$

This can be rewritten as:

$Total = -8 * 4$

The product, when written as sum is:

$Total = (-8) +(-8) +(-8) +(-8)$

Simplify each expression t+8t

FromTheMoon [43]

Think of it this way. Let's say t= one. 1+8 is 9. Your answer is 9t. Think of a variable without a number as one.

identify the coordinates of four points on the line with each given slope and y-intercept. slope=-1 and that y-intercept=8

VladimirAG [237]

Answer:

[-1, 9], [-2, 10], [-3, 11], [1, 7]

Step-by-step explanation:

Starting from the y-intercept of [0, 8], I did rise\run by moving one block north over one block west for the first three coordinates, but retracing back to the y-intercept, I moved one block south over one block east for the last coordinate. It does not matter where you go, as long as you follow the pattern within this rate of change [slope].

I am joyous to assist you anytime.
