Find the measure of the indicated angle to the nearest degree. A. 36 B. 30 C. 54 D. 60

STatiana [176]

Answer:

54 degrees

Step-by-step explanation:

This is trigonometry. So we are given the adjacent leg and hypotenuse. So we can use cosine(cah from soh cah toa)

We will have to use the inverse of the trig ratios.

Remember!

cos^-1 is not 1/cos(that is sec)

cos^-1(27/46)

acos(27/46)

54.0586701 and so on

Round to nearest degree 54

Someone please please help me with this ! I would really appreciate it

Answer:

Both volumes are the same

Step-by-step explanation:

Volume of cylinder = $\pi$ $r^{2} h$

r = radius

h = height

Since area of the circle is given on top,

Area of a circle = $\pi$ $r^{2}$

We know the area is 12

12 = $\pi$ $r^{2}$ (we need to find r)

r = $\sqrt{\frac{12}{\pi} }$

r = 1.954

Now we can find the cylinder's volume:

Volume of cylinder = $\pi$ $(1.954)^{2}$ (6)

Volume of cylinder = 72

To find the volume of the cuboid, we use

Volume of cuboid = lwh

l = length

w = width

h = height

Volume of cuboid = 6 x 4 x 3

Volume of cuboid = 72

This proves that both the volumes are the same.

At a local sandwich shop the average customer spends $25 at dinner with a standard deviation of $2.30. In a simple random sample

oee [108]

Answer:

The probability that the mean receipt for dinner is between $24.50 and $25.50 is

P(24.50≤ x ≤ 25.50)= 0.8324

Step-by-step explanation:

Step(i):-

Given mean of Population(μ) = $25

Given standard deviation of the Population (σ) = 2.30

Sample size 'n' = 40

Let 'X' be the random variable in normal distribution

Given X₁ = 24.50

$Z_{1} =\frac{x-mean}{\frac{S.D}{\sqrt{n} } } = \frac{24.50-25}{\frac{2.30}{\sqrt{40} } } = -1.375$

Given X₂ = 25.50

$Z_{2} =\frac{x-mean}{\frac{S.D}{\sqrt{n} } } = \frac{25.50-25}{\frac{2.30}{\sqrt{40} } } = 1.3751$

Step(ii):-

The probability that the mean receipt for dinner is between $24.50 and $25.50

P(x₁≤ x ≤ x₂) = P(Z₁≤ z ≤ Z₂) = A(Z₂) + A(z₁)

P(24.50≤ x ≤ 25.50) = P(-1.375≤ z ≤ 1.375) = A(1.375) + A(1.375)

P(24.50≤ x ≤ 25.50)= 2 A( 1.375)

= 2 × 0.4162 ( from normal table)

= 0.8324

Final answer:-

The probability that the mean receipt for dinner is between $24.50 and $25.50 is 0.8324
