Consider the graphs of f(x) and g(x).

butalik [34]

Answer:

The value of k is -7

Step-by-step explanation:

We are given the graph of f(x) and g(x). If g(x)=f(x)+k

If we shift f(x) k unit vertical get g(x).

If k>0 then shift up

If k<0 then shift down.

f(x) and g(x) are both parabola curve.

First we find the vertex of f(x) and g(x)

Vertex of f(x) = (3,1)

Vertex of g(x) = (3,-6)

We can see change in y co-ordinate only.

f(x) shift 7 unit down to get g(x)

g(x)=f(x)-7

Therefore, The value of k is -7

7. Patrick tosses a penny and a number cube, with faces numbered 1 through 6, at the

lions [1.4K]

Answer:

B. 1/3 or 33.3%

Step-by-step explanation:

H- 1 ,2 ,3, 4, 5, 6

T- 1, 2, 3, 4, 5, 6

Multiples of 3: 3, 6, 9, 12, etc..

2/6 simplified is 1/3

So, the probability that the penny will land on heads and the number cube will land on a multiple of 3, is 1/3 or 33.3%

A limnologist wishes to estimate the mean phosphate content per unit volume of lake water. It is knownfrom studies in previous y

telo118 [61]

Answer: 68

Step-by-step explanation:

As per given , we have

Population standard deviation : $\sigma=4$

Critical value for 90% confidence interval = $z_{\alpha/2}=1.645$

Margin of error : E= 0.8 milligrams

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

$n=(\dfrac{z_{\alpha/2}\ \sigma}{E})^2$

i.e. $n=(\dfrac{(1.645)(4)}{0.8})^2=(8.225)^2$

$=67.650625\approx68$

Hence, the limnologist must analyze 68 samples.
