Answer:

P( green or blue) = 9/20

P( green, yellow or blue) = 3/4

P( green, red or blue) = 7/10

Step-by-step explanation:

There are 40 slips in all, Green: 15, Red: 10, Blue: 3, Yellow: 12.

P( green or blue) = green or blue / total

= (15 + 3)/ 40

= 18/40

= 9/20

P( green, yellow or blue) = green yellow or blue / total

= (15+12 + 3)/ 40

= 30/40

= 3/4

P( green, red or blue) = green red or blue / total

= (15+10 + 3)/ 40

= 28/40

= 7/10

Answer:

Step-by-step explanation:

The first one is 18/40, which reduced to lowest terms, is 9/20.

Imagine there are 5 cards. They are colored red, yellow, green, white, and black. You mix up the cards and select one of them wi

iragen [17]

Step-by-step explanation:

step one:

given that the sample space is

red, yellow, green, white, and black. i.e (1+1+1+1+1)= 5

the sample size is 5

the probability of picking a colored card at random is

Pr(a colored card)= 1/5

step two:

without replacement, after the first event, the sample size is now 4

then the probability of picking a colored card at random is

Pr(a colored card)= 1/4

Which is 5logx - 6log(x-8) written as a single logarithm?

ira [324]

Answer:

option a

$log\frac{x^{5} }{(x-8)^{6} }$

Step-by-step explanation:

Given in the question an expression

5logx - 6log(x-6)

To solve this question we will apply two of the logarithm property

1) power rule

alogx = log $x^{n}$

log $x^{5}$ - log $(x-8)^{6}$

2) substraction rule

The log of a quotient is the difference of the logs

loga (x/y) = loga x - loga y

$logx^{5}- log(x-8)^{6}$

log $\frac{x^{5} }{(x-8)^{6} }$

Solve 8n + 20 < 6n + 24

antoniya [11.8K]

Answer:

n < 2

Step-by-step explanation:

This inequality can be solved the same way the corresponding 3-step linear equation would be solved.

8n +20 < 6n +24 . . . . . given

2n +20 < 24 . . . . . . . . step 1, subtract 6n to isolate the variable on the left

2n < 4 . . . . . . . . . . . . step 2, subtract 20 to separate constants and variable terms

n < 2 . . . . . . . . . . . divide by the coefficient of the variable

Jason bought 6 movie tickets and four bags of popcorn Michael bought two movie tickets and three bags of popcorn each bag of pop

svlad2 [7]

Answer:

Equation is $8M + 7P = 131$

$M = \$12$

Step-by-step explanation:

Given

Jason: 6 Movies and 4 popcorn

Michael: 2 Movies and 3 Popcorn

1 Popcorn = $5

Total = $131

Required

- Write an equation to solve

<em>Represent Movie with M and Popcorn with P</em>

For Jason, we have:

6M + 4P

For Michael, we have:

2M + 3P

Add these parameters together

Jason + Michael = $131

$6M + 4P + 2M + 3P = 131$

Collect Like Terms

$6M + 2M+ 4P + 3P = 131$

$8M + 7P = 131$

Hence the equation is $8M + 7P = 131$

From the question, we have that

$P = \$5$

Substitute 5 for P

$8M + 7 * 5 = 131$

$8M + 35 = 131$

Solve for M

$8M = 131 -35$

$8M = 96$

$M = \frac{96}{8}$

$M = \$12$
