What is the value of x

Mathematics
1 answer:
Amiraneli [1.4K]4 years ago
7 0

Answer:

x = 37.53

Step-by-step explanation:

Tan theta = opposite/adjacent

tan 47 = x /35

Multiply each side by 35

35 tan 47 = x/ 35 * 35

35 tan 47 = x

37.53290485=x

To two decimal places

x = 37.53

Find the volume of the right cone
sleet_krkn [62]
Hi, thank you for posting your question here at Brainly. I hope I would be able to help you with my simple explanation:)

To calculate for the volume of a cone, the formula would be

V = 1/3*pi*r²*h

where r = 12 cm, h = 8 cm
So,

V = 1/3*pi*12²*8
V = 384*pi

You order seventeen burritos to go from a Mexican restaurant, seven with hot peppers and ten without. However, the restaurant fo
Kisachek [45]

Answer:

P=0.369

Step-by-step explanation:

In this binomial probability case, the success is to pick a burrito with hot peppers, there are 7 out of 17, the probability is p=7/17=0.4118. The formula is

P=_nC_kp^k(1-p)^{n-k}

Where n is the number of burritos taken at random, k is the number of success (burrito with hot peppers), p is the probability of success. _nC_k denotes the number of combinations and its formula is:

_nC_k=\frac{n!}{k!(n-k)!}

At least two burritos have hot peppers means having two or three burritos, these two cases are calculated and sum to get the probability of at least two burritos that have hot peppers.

P=_nC_kp^k(1-p)^{n-k}=\frac{n!}{k!(n-k)!}p^k(1-p)^{n-k}

P_2=\frac{3!}{2!(3-2)!}(0.4118)^2(1-0.4118)^{3-2}=\frac{3\times2!}{2!1!} (0.1696)(0.5882)^1\\P_2=3 (0.1696)(0.5882)=0.2993

P_2=\frac{3!}{3!(3-3)!}(0.4118)^3(1-0.4118)^{3-3}=\frac{1}{0!} (0.0698)(0.5882)^0\\P_2=1 (0.0698)(1)=0.0698

P=P_2+P_3=0.2993+0.0698=0.3691

Round to three decimal places: P=0.369
