Answer:

Percentage of boys have school dinners: 60%

Percentage of pupils in this class have school dinners: 65%

Step-by-step explanation:

<u>1.</u> There are: 6+4 = 10 boys in the class ->  corresponding to 100 %

1 boy is corresponding to 100% :10 = 10%

6 in 10 have school dinners -> 10% x 6 = 60%

<u>2.</u> There are 10( boys) + 7 (girls) + 3 (girls) = 20 pupils in the class -> corresponding to 100%

1 pupil is corresponding to 100% : 20 = 5%

There are : 6 + 7 = 13 pupils who have school dinners

13 in 20 have school dinners -> 5% x 13 = 65%

3x+2y=3y-2 line 1 x+y=10 line 2 solve for x/y
GrogVix [38]

Answer:

x/y=1/4

Step-by-step explanation:

3x+2y=3y-2

3x=3y-2y-2

3x=y-2

y=3x+2

x+y=10

x+3x+2=10

4x+2=10

4x=10-2

4x=8

x=8/4

x=2

2+y=10

y=10-2

y=8

x/y=2/8=1/4

You consider yourself a bit of an expert at playing rock-paper-scissors and estimate that the probability that you win any given
cestrela7 [59]

Answer:

a) 0.37

b) 0.421

c) 0.25

Step-by-step explanation:

Since the probability of winning a game is binomial (P = 0.5) the expected value for number of winning when you play 60 games is

\mu = 60*0.5 = 30

And the standard deviation:

\sigma = 60*0.5*0.5 = 15

a) the cumulative probability of winning at least 35 games is

P(X \geq 35) = 1 - P(X < 35) = 1 - 0.631 = 0.37

b)P(X < 27) = 0.421

c)P(30 \leq X \leq 40) = P(X \leq 40) - P(X \leq 30) = 0.75 - 0.5 = 0.25

Need help with this please
Sav [38]
Your going to have to use the distance formula for these questions which is the square root of (x sub 2 - x sub 1) + (y sub 2 - y sub 1). For number 1 your coordinates are (-5,5) and (1,-2). Substituting these values into the formula your answer for number 1 is 9.2.
