Can someone answer this question please answer it correctly if it’s corect I will mark you brainliest
lana [24]

Answer:

1/21

Step-by-step explanation:

Cards: 2,3,4,5,6,7,8      7 cards

1st card :5

P(5) = number of 5's / total

       = 1/7

Then we keep the card

Cards: 2,3,4,6,7,8   only 6 cards left

card less than 4: 2,3

P (card less than 4)  = number of cards less than 4/ total cards

                                  = 2/6 = 1/3

P (5, no replacement, card less than 4) = P(5) * P( less than 4)

                                                                 = 1/7 * 1/3

                                                                  =1/21

Kassie recorded the favorite sport of students at her school. She surveyed 800 students. How many more students chose Baseball t
lisov135 [29]

Answer:

40 more kids chose baseball over basketball.

Step-by-step explanation:

The best way to go about this is to use benchmark percentages.

For baseball, 25% of 800 people chose that, so we can do 800/4 to get 200, so 200 students chose baseball

For basketball, we could do 800/5 but that isn't mental math, so we can do 10% of 800 is 80 and 80*2=160. So 40 more kids chose baseball over basketball.

A photocopier increased the sides of a square in the ratio 4:5.
Svetach [21]

Answer:

The sides are increased by a percentage of 25%

Step-by-step explanation:

Let

x -----> the length side of the original square

y ----> the length side of the increased square

we have

\frac{x}{y} =\frac{4}{5}

y=\frac{5}{4}x

y=1.25x

the increase is calculated by subtracting x from y

so

y-x=1.25x-x=0.25x

Remember that

0.25=\frac{25}{100}=25\%

therefore

The sides are increased by a percentage of 25%
