Can a triangle with the angles of 0, 90 , and 90 be considered a triangle?

asambeis [7]

A "triangle" with the angles 0, 90, and 90 degrees cannot be considered a triangle since the two 90 degree angles make a right angle, and 0 degrees would mean a flat line. Rather it would resemble something like a straight U that is stretched sideways.

A restaurant has two different seating options: a table and a family booth. A table can seat 4 people, and a family booth can se

krok68 [10]

Answer: 242 = 190 + 4t

Step-by-step explanation:

You know that the maximum capacity of the restaurant is 242 people, meaning that at most there can only be that many customers seated at that time. Normally, the equation would be 242 = 10b + 4t, but since you already know the number of booths, your work is cut in half, giving you 242 = 10(19) + 4t. The equation would be this because you have the capacity being equal to the number of tables x the number of people at each table and the number of booths x the number of people seated at each of them.

An unconfined compression test was performed to determine the average strength of concrete cylinders (in psi). It is believed th

Ronch [10]

Answer:

Explained below.

Step-by-step explanation:

(1)

The confidence level is, 91%.

Compute the value of α as follows:

$\text{Confidence level}\% =(100-\alpha \%)\\\\91% = 100-\alpha \%\\\\\alpha \%=100-91\%\\\\\alpha \%=9\%\\\\\alpha =0.09$

(2)

As the population standard deviation is provided, i.e. σ = 256 psi, the z value would be appropriate.

The z value for α = 0.09 is,

z = 1.69

(3)

Compute the 91% confidence interval as follows:

$CI=\bar x\pm z_{\alpha/2}\cdot\frac{\sigma}{\sqrt{n}}$

$=3000\pm 1.69\cdot\frac{256}{\sqrt{70}}\\\\=3000\pm 51.71\\\\=(2942.29, 3057.71)$

(4)

The 91% confidence interval for population mean implies that there is a 0.91 probability that the true value of the mean is included in the interval, (2942.29, 3057.71) psi.

Yair is buying a dog carrier for his puppy. The carrier is 20 inches long, 13 inches wide, and 16 inches high. What is the volum

scZoUnD [109]

Answer:

4160 cubic inches

Step-by-step explanation:

The dog carrier is in the shape of a rectangular prism (cuboid).

The volume of a rectangular prism is given as:

V = L * W * H

where L = length, W = width, H = height

The carrier is 20 inches long, 13 inches wide, and 16 inches high.

Therefore, its volume is:

$V = 20 * 13 * 16\\V = 4160 in^3$

The volume of the dog carrier is 4160 cubic inches.
