Allen's hummingbird (Selasphorus sasin) has been studied by zoologist Bill Alther.† Suppose a small group of 10 Allen's hummingb

ruslelena [56]

Answer: provided in the explanation segment

Step-by-step explanation:

(a). from the question, we can see that since that б is known, we can use standard normal, z.

we are asked to find an 80% confidence interval for the average weights of Allen's hummingbirds in the study region. What is the margin of error?

⇒ 80% confidence interval for the average weight of Allen's hummingbirds is given thus;

x ± z * б / √m

which is

3.15 ± 1.28 * 0.32/√10

= 3.15 ± 0.1295 = 3.0205 or 3.2795

(b). normal distribution of weight (c) б is known

(c). option (a) and (e) are correct

(d). from the question, let sample size be given as S

this gives';

1.28 * 0.32/√S = 0.15

√S = (1.28 * 0.32) / 0.15 = 2.73

S = 7.4529

Jackson's rectangular orchard is 6 km long and 4 km wide. What is the area of Jackson's orchard?

Levart [38]

For a rectangle area, use base x height, or length x width.

6 km long x 4 km wide = 24 km

The area of Jackson's orchard is 24 km

The graph of f (in blue) is translated a whole number of units horizontally and vertically to obtain the graph of h(in red).

saveliy_v [14]

Answer:

$h(x)=\sqrt{x-2}+4$

Step-by-step explanation:

Initially the graph f (x) is shifted horizontally to the right.

When the graph shifts to right the function then becomes

f(x)→f(x-b)

Where b is the units by which it is shifted towards right .

So, in the figure we can see that it is shifted 2 units to the right .

So, f(x)→f(x-2)

Since f(x) is $\sqrt{x}$

So, f(x-2) = $\sqrt{x-2}$

Now the new obtained graph is again shifted vertically upward

When the graphs shifts upward f(x) →f(x)+b

where b is the units by which it is shifted upward

So, our obtained f(x-2) when shifted upward by 4 units so using the above given transformation of upward shift i.e. f(x) →f(x)+b

So, Our new graph h(x) = f(x-2)+4

⇒ $h(x)=\sqrt{x-2}+4$
