If 18 percent of the beads in a bag are green, 25 percent are red and 40 percent are purple. What is the probablity of choosing

sweet [91]

Answer:

$P(G\ then\ R)=0.045$

Step-by-step explanation:

From the question we are told that:

Percentage of Green beads $P_g=18$

Percentage of Red beads $P_r=18$

Percentage of Purple beads $P_p=18$

Therefore

Probability of choosing a Green bead is

$P(G)=0.18$

Probability of choosing a Red bead is

$P(R)=0.25$

Generally the equation for choosing a green bead then a red bead is mathematically given by

Since Outcomes are independent

$P(G\ then\ R)=0.18*0.25$

$P(G\ then\ R)=0.045$

carey is trying to decide between two guitars. the first had an original price of $160, but is on sale for $100. the second had

MrMuchimi

To determine the percent change in price, solve for the differences between the original prices and the sale prices. Then, divide the difference by the original price and multiply by 100%.

Guitar 1: (($160 - $100) / $160) x 100% = 37.5%
Guitar 2: (($250 - $150) / $250) x 100% = 40%

Thus, guitar 2 has a greater percent change in price.

Joshua has math and reading homework tonight. Joshua can solve each math problem in 2.5 minutes and he can read each page in 3 m

liraira [26]

Answer:

Joshua solved 7 math problems and tread 14 pages.

Step-by-step explanation:

Let x be the number of math problems Joshua solved. The number of pages Joshua read is twice the number of math problems he solved, then 2x is the number of pages Joshua read.

Joshua can solve each math problem in 2.5 minutes, then x math problems he solves in 2.5x minutes.

Joshua can read each page in 3 minutes, then 2x pages he reads in $3\cdot 2x=6x$ minutes.
