Can someone help me with this Geometry problem, please?
Doss [256]

Hello from MrBillDoesMath!

Answer:

72


Discussion:

Total Surface area = area of pyramid base + 4 ( area of triangular face)

In our case this becomes

                                 4*4                               + 4(  (1/2) (4)(7) )  =

                                 = 16 + (2)(4)(7)

                                 = 16 + 56        

                                 = 72

which is the first choice.  

Note: the area of a triangular face was computed using (1/2) b h, which in our case is

(1/2) (4) (7)


Thank you,

MrB

What are the dimensions
kobusy [5.1K]

Answer:

456 sq. units

Step-by-step explanation:

Formula for the area of the square:

b(base)*h(height)

b=21

h=16

21*16=336

Formula for the area of the triangle:

b*h/2

b=36-21=15

h=16

15*16/2=120

Add the two shaped together:

336+120=456

Label your answer: 456 sq. units

5x-7=5x bud it no solution one solution infinitely many solutions
blagie [28]

Answer:

When you add 2+3 which equals 5 so it’ll be y=5x-7. And plug in y into the other equation. 5x-7-5x+8=0. -7-8=0, -7-8 =-1 therefore there is no solution because-7-8= -1 not 0.

A group of veterinary researchers plan a study to estimate the average number of enteroliths in horses suffering from them. Prev
ycow [4]

Answer:

1.) 107 observations

2.) the best veterinary hospital is likely to see the most severe cases with larger number of enteroliths

3.) A. sample size is too small for the central limit theorem to apply.

4.) The test requires that the sample mean is normally distributed; this requires that either the population distribution is Normal or the sample size exceeds 30.

5.) a Type I error

Step-by-step explanation:

n = [(Zcritical * σ) ÷ E]²

n = sample size

Zcritical at 99% = 2.58

E = error margin = 0.5

Standard deviation, σ = 2

n = [(2.58 * 2) ÷ 0.5]²

n = [5.16 ÷ 0.5]²

n = (10.32)²

n = 106.5024

n = 107 observations

B.) The thought or decision that the best veterinary hospital is likely to see the most severe cases with larger number of enteroliths will introduce a bias in the study.

C.) For central limit theorem ; sample size must be considerably large ; at least sample size, n ≥ 30

D.) Distribution must be normal it approximately normal, obeying the central limit theorem ; sample size must be considerably large ; at least sample size, n ≥ 30
