Answer:

Part A: Up 9

Part B: Up 6

Step-by-step explanation:

Part A: The graph appears to be a cosine graph since it starts at a peak on the y-axis. Normally a cosine graph starts at (0,1). This graph begins at (0,10). It has been shifted up y a translation by 9.

Part B: Each trig equation has a basic structure f(x) = a sin (x+b) + k where:

a is the vertical stretch
b is the horizontal shift
k is the vertical shift

A vertical translation is a vertical shift and is represented by the value in k added outside of the function. In the equation f(x) = 2sin(θ + 120°) + 6, k = 6. The vertical translation is 6.

It's believed that as many as 23% of adults over 50 never graduated from high school. We wish to see if this percentage is the

laila [671]

Answer: 756

Step-by-step explanation:

Given : The proportion of adults over 50 never graduated from high school. = 0.23

Margin of error : E=0.03

Significance level : $\alpha=1-0.95=0.05$

Critical value : $z_{\alpha/2}=1.96$

The formula to find the sample size is given by:_

$n=p(1-p)(\dfrac{z_{\alpha/2}\ }{E})^2$

i.e. $n=(0.23)(0.77)(\dfrac{(1.96)}{0.03})^2=755.941511111approx756$

Hence, the required minimum sample size = 756

Bill and George go target shooting together. Both shoot at atarget at the same time. Suppose Bill hits the target withprobabilit

german

Answer: (a) $\frac{2}{9}$ (b) $\frac{6}{41}$

Step-by-step explanation:

(a) P( Bill hitting the target) = 0.7 P( Bill not hitting the target) = 0.3

P( George hitting the target) = 0.4 P(George not hitting the target) = 0.6

Now the chances that exactly one shot hit the target is = 0.7 x 0.6 + 0.4 x 0.3

= 0.54

Chances that George hit the target is = 0.4 x 0.3 = 0.12

So given that exactly one shot hit the target, probability that it was George's shot = $\frac{0.12}{0.54}$ = $\frac{2}{9}$ .

(b) The numerator in the second part would be the same as of (a) part which is 0.12.

The change in the denominator will be that now we know that the target is hit so now in denominator we include the chance of both hitting the target at same time that is 0.4 x 0.7 and the rest of the equation is same as above i.e.

Given that the target is hit,probability that George hit it = $\frac{0.4\times 0.3}{0.7\times 0.6 +0.4\times 0.3+0.4\times 0.7}$ = = $\frac{6}{41}$
