8 0

Step-by-step explanation:

a.
if x=-1 then,
y=2*(-1)-1
y=-2-1
y=-3

if y=-1 then,
-1=2x-1
-2x=-1+1
-2x=0
x=0

if x=1 then,
y=2*1-1
y=2-1
y=1

if y=3 then,
3=2x-1
-2x=-1-3
-2x=-4
-2/-2x=-4/-2
x=2

b.
if x=0 then,
0+y=-2
y=-2

if x=1 then,
y+1=-2
y=-1-1
y=-3

if x=2 then,
y+2=-2
y=-2-2
y=-4

if x=3 then,
y+3=-2
y=-2-3
y=-5

Answer:

Step-by-step explanation:

h(t) = -16t² + 14400

0= -16t² + 14400

(1/-16)×-14400=-16t²(1/-16)

900=t²

$\sqrt{900} =\sqrt{t^{2}}$

According to the manufacturer of the candy Skittles, 20% of the candy produced are red. If we take a random sample of 100 bags o

igomit [66]

Answer:

Probability that the proportion in our sample of red candies will be less than 20% is 0.5 .

Step-by-step explanation:

We are given that 20% of the candy produced are red. A random sample of 100 bags of Skittles is taken.

The distribution we can use here is;

$\frac{\hat p - p}{\sqrt{\frac{\hat p (1- \hat p)}{n} } }$ ~ N(0,1)

where, p = 0.20 and n = 100

Let $\hat p$ = proportion of red candies in our sample

So, P( $\hat p$ < 0.20) = P( $\frac{\hat p - p}{\sqrt{\frac{\hat p (1- \hat p)}{n} } }$ < $\frac{0.20 - 0.20}{\sqrt{\frac{0.2 (1- 0.2)}{100} } }$ ) = P(Z < 0) = 0.5

Therefore, probability that the proportion in our sample of red candies will be less than 20% is 0.5 .
