All the select drop box is. are not and are
Brilliant_brown [7]

Answer:

Step-by-step explanation:

Corresponding angles of both the squares are congruent. (angles of a square measure 90°)

Ratio of the sides of the given squares = \frac{\text{Side length of small square}}{\text{Side length of the large square}}

                                                                 = \frac{2}{5}

This ratio of side lengths is constant for all corresponding sides.

Therefore, corresponding sides are proportional.

Since, all angles of both the squares are congruent and all the sides are proportional, both the squares will be similar.

Scale factor = \frac{\text{Side length of large square}}{\text{Side length of the smaller square}}

                    = \frac{5}{2}

                    = 2.5

This sequence of similarity transformations shows the figures are similar.

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

cheers i hope this helps

Answer: \boxed{\bold{\left(2u-7\right)^2}}

<><><><><>

Explanation: \downarrow\downarrow\downarrow

<><><><><>

[ Step One ] Rewrite \bold{4u^2-28u+49}

\bold{\left(2u\right)^2-2\cdot \:2u\cdot \:7+7^2}

[ Step Two ] Apply perfect square formula

Note: Perfect Square Formula: \bold{\left(a-b\right)^2=a^2-2ab+b^2}

\bold{a=2u,\:b=7}

\bold{\left(2u-7\right)^2}
