18 7/10 liters of milk does he milk from both cows.

According to the question

Mr. benjamin milk 8 1/5 from the black cow and 10 1/2 liters of the brown cow

Milk from both cows

= 8 1/5 + 10 1/2

converting mixed fraction into proper fraction

8 1/5 = \frac{8 \times 5 +1}{5} = 41/5

10 1/2 = \frac{10 \times 2 +1}{2} = 21/2

= \frac{41}{5} +\frac{21}{2}

= \frac{2 \times 41+21 \times 5}{10}

= \frac{82+105}{10}

= \frac{187}{10}

converting fraction into mixed fraction

= \frac{180+7}{10}

= 18 7/10

Therefore,

18 7/10 liters of milk does he milk from both cows.

We would like to construct a 99% confidence interval for the mean, based on a sample of 50 observations. The sample standard dev
Sloan [31]

Answer:

Lower confidence limit = 20.191

Step-by-step explanation:

Sample mean; x' = 22

Sample standard deviation; s = 5.5

Sample size; n = 50

Confidence interval = 99%

Since sample size > 30, we will use the formula;

CI = x' ± zs/√n

Where;

x' is sample mean

s is sample standard deviation

n is sample size

z is z-value of the confidence interval

From the table attached, z for 99% = 2.3263

Thus;

CI = 22 ± (2.3263 × 5.5)/√50

CI = 22 ± 1.809

CI = 23.809 or 20.191

Lower confidence limit = 20.191

ASAP What is the lateral area of this regular octagonal pyramid?? Explain your answer if you can plz thanks
Archy [21]
The lateral area would be 298.7 cm².

The lateral area is the area of all of the lateral faces of the pyramid.  There are 8 triangles making up the lateral faces.  Each has a base of 6.6.  The formula for the area of a triangle is

A=1/2bh,

so we still need the height of the triangle.

The height of each lateral triangle is the slant height of the pyramid.  The slant height of the pyramid forms a right triangle with the height of the pyramid and the "radius" as it were of the pyramid.  Thus we use the Pythagorean theorem:

8²+8²=h²
64+64=h²
128=h²
√128=√(h²)
8√2 = h

Substituting this into our area formula we have:
A=1/2(6.6)(8√2)

We will go ahead and multiply this by 8, since there are 8 lateral faces:
LA=8(1/2)(6.6)(8√2)
LA = 298.7
