Can someone please help me

grandymaker [24]

Answer:

1) Yes

Product of Means = Product of Extremes

4 × 21 = 7 × 12

84 = 84

2) No

Product of Means = Product of Extremes

2 × 2 = 3 × 3

4 ≠ 9

3) No

Cross multiplying

3 × 6 = 4 × 8

18 ≠ 32

4) Yes

Cross Multiplying

1 × 25 = 5 × 5

25 = 25

In a random sample of 49 audited estate tax returns, it was determined that the mean amount of additional tax owed was $3410 w

GREYUIT [131]

Answer:

$2948 and $4030

Step-by-step explanation:

The CI is sample mean +/- s/sqrt(n)

t(0.95,df=63 critical values are |t|>1.669

90% CI is 3489+/-1.669*(2595/8) since sqrt(64)=8

the interval is 541.38

round to 541

the interval is 3489+/-541

($2948,$4030) is the 90% CI for the mean.

How many feet tall is the building

Fantom [35]

Answer:

Height of the building = 77 ft.

Step-by-step explanation:

Let the height of the building (AB) = h feet

It's given that height of a woman (ED) = 5 feet 3 inches

≈ 5 feet + $\frac{3}{12}$ ft

≈ 5.25 ft

Length of the shadow (BC) of the building = 55 ft

Length of the shadow (DC) of the woman = 45 in ≈ 3.75 ft

Since, both the triangles ABC and EDC are similar, their corresponding sides will be proportional.

By the property of similar triangles,

$\frac{AB}{ED}= \frac{BC}{DC}$

$\frac{h}{5.25}=\frac{55}{3.75}$

h = $\frac{55\times 5.25}{3.75}$

h = 77 ft

Therefore, height of the building will be 77 ft.
