Tresset [83]

Answer:

x = 28/3

Step-by-step explanation:

We can solve this problem by using similar triangles:

Both of these triangles have a 90 degree angle and they share angle A, meaning that they are similar by AA similarity.

Now we can set up ratios and solve:

13/7 = (x+8)/x

multiply both sides by x:

13x/7 = x+8

Multiply both sides by 7:

13x = 7x + 56

move the 7x over and divide by 6:

6x = 56

x = 28/3

It is known that 60 percent of all registered voters in the 42nd Congressional District are Republicans. Three registered voters
Gelneren [198K]

Answer:

0.11

Step-by-step explanation:

Let x be a random variable representing the number of registered voters in the congressional district. This is a binomial distribution since the outcomes are two ways. It is either a randomly selected registered voter is a conservative or not. The success would be that a randomly selected voter is a conservative. The probability of success, p = 60/100 = 0.6

The probability of failure, q would be 1 - p = 1 - 0.6 = 0.4

Given n = 10, we want to determine P(x = 4)

From the binomial distribution calculator,

P(x = 4) = 0.11

Find the 10th term in the following arithmetic sequence if the constant being added is
Murljashka [212]

Find the 10th term in the following arithmetic sequence if the constant being added is  -12

Step-by-step explanation:

20 - 12 = 8

8 - 12 = -4

-4 - 12 = -16

So the sequence will be

20; 8; -4; -16

an = 20 - 12(n - 1)

a10 = 20 - 12(10 - 1) = -88

Height of men on a baseball team have a bell-shaped distribution with a mean of 180 cm and a standard deviation of 8 cm. using t
Lapatulllka [165]

Answer:

a. 99.7%

b. 68%

Step-by-step explanation:

The empirical rule for approximately symmetrical and bell-shaped distributions states that:

68% of the data are among the values  (means - sd) and (means + sd)

95% of the data are among the values  (means - 2*sd) and (means + 2*sd)

99.7% of the data are among the values (means - 3*sd) and (means + 3*sd). So that,

68% of the data are among the values  (180 - 8) = 172 and (180 + 8) = 188

95% of the data are among the values  (180 - 16) = 164 and (180 + 16) = 196

99.7% of the data are among the values (180 - 24) = 156 and (180 + 24) = 204
