find the value of x then classify the triangle by its angles

Answers

Answer:

x = 134°

Step-by-step explanation:

Let

[tex]\angle A=64^{\circ}\\\\\angle B =70^{\circ}[/tex]

We need to find the value of x.

We can see from the figure that x is exterior angle. To find x we can use exterior angle theorem. According to this theorem,

[tex]x=\angle A+\angle B\\\\x=64+70\\\\x=134^{\circ}[/tex]

Hence, the value of x is 134°

What is the missing value in the proportion? Solve for M and round your answer to the nearest hundredth.

Answers

Answer:

M = 165.66

Step-by-step explanation:

Given the proportion, [tex] \frac{M}{178} = \frac{188}{202} [/tex], gif ind the value of M, start by multiplying both sides by 178

[tex] \frac{M}{178} \times 178 = \frac{188}{202} \times 178 [/tex]

[tex] M = \frac{188 \times 178}{202} [/tex]

The half-life of cesium-137 is 30 years. Suppose we have a 20 mg sample.

a. Find the mass (in mg) that remains after t years.
b. How much of the sample (in mg) remains after 20 years?
c. After how long will only 1 mg remain?

Answers

Answer:

(a) A = (20mg)/(2^(t/30))

(b) 12.6mg

(c) 129.6years

Step-by-step explanation:

To calculate the amount remaining after a number of half-lives, n, we can make use of:

[tex]A = \frac{B}{2^n}[/tex]

Where A = amount remaining

B = initial amount

[tex]n = \frac{t}{t_{0.5}}[/tex]

(a) A = (20mg)/(2^(t/30))

(b) Mass after 20years

A = (20mg)/(2^(20/30)) ≈ 12.6mg

(c) After how long will only 1mg remain:

1mg = (20mg)/(2^(t/30))

[tex]20mg = {2^{\frac{t}{30}}[/tex]

Taking log of both sides we have:

Log(20) = (t/30)log(2)

t/30 = (log(20))/(log(2)) ≈ 4.3

t/30 = 4.3

t = 30 x 4.3 ≈ 129.6years.

According to a survey conducted by Deloitte in 2017, 0.4702 of U.S. smartphone owners have made an effort to limit their phone use in the past. In a sample of 54 randomly selected U.S. smartphone owners, what is the probability that between 22 and 29 (inclusively) will have attempted to limit their cell phone use in the past?
1) 0.0241.
2) 0.1703.
3) 0.8779.
4) 0.0483.
5) 0.1221.

Answers

Answer: 0.628

Step-by-step explanation:

Probability of U.S. smartphone owners have made an effort to limit their phone use in the past : p = 0.4702

Sample size : n= 54

Mean : [tex]\mu =(54)(0.4702)=25.39[/tex]

Standard deviation:

[tex]\sigma=\sqrt{(54)(0.4702)}=\sqrt{25.39}\\\\\approx5.039[/tex]

The probability that between 22 and 29 (inclusively) will have attempted to limit their cell phone use in the past will be :

[tex]P(22\leq x\leq29)=P(21<x<30)=P(\dfrac{21-25.39}{5.039}<\dfrac{X-\mu}{\sigma}<\dfrac{30-25.39}{5.039})\\\\=P(-0.8712<z<0.914864)\ \ \ \ [z=\dfrac{X-\mu}{\sigma}]\\\\=P(z<0.914864)-P(z<-0.8712)\\\\=P(z<0.914864)-(1-P(z<0.8712))\\\\=0.8198685-(1-0.8081775)\ \ \ [\text{ By p-value table}]\\\\=0.628046[/tex]

Hence, the required probability = 0.628

How many ways are there to rearrange the letters ALIVE in such a way that the word EVIL is not contained in the resulting word

Answers

Answer: 118 combinations.

Step-by-step explanation:

In ALIVE we have 5 letters, rearranging it we have the possible options of:

5 options for the first letter.

4 options for the second letter, as one was already chosen for the first one

3 options for the third letter, as 2 were already chosen.

2 options for the fourth letter.

1 option for the last letter.

The total number of combinations will be equal to the product of the numbers of options for each letter, then we have:

5*4*3*2*1 = 120 combinations.

And the combinations where the word EVIL is formed are:

AEVIL

EVILA

2 combinations, then the total number of combinations such that the word evil is not formed are:

120 - 2 = 118 combinations.
