Well assuming that this would be a typical triangle, and not a right angle one, knowing that the sum of all sides adds up to 180 degrees, simply add all of the expressions and one value and make it equal to 180, and then solve for x.

(6x-1) + (X+14) + 20 = 180
6x - 1 + X + 14 = 160
7x - 1 + 14 = 160
7x + 13 = 160
7x = 147
X = 21.

Now solve for the angles by plugging in X.

A = 6x - 1 = 6(21) - 1 = 125 degrees
C = X + 14 = (21) + 14 = 35 degrees.

I believe these are the solutions.

(1 point) A random sample of 600 movie goers in Flagstaff found 252 movie goers who had bought popcorn on their last visit. Find

garik1379 [7]

Answer-

A 95% confidence interval for the true percent of movie goers is 36.41% to 44.25%

Solution-

Given,

n = 600 (sample size)

x = 252 (number of people who bought)

Confidence interval = 95%, so z = 1.96

We know that,

$\mu = M\pm Z(SE)$

where,

M = sample mean

Z = Z statistic determined by confidence level

SE = standard error of mean

Calculating the values,

$M=\frac{x}{n} =\frac{242}{600} =0.4033$

$Z=1.96$ from the tables

$SE=\sqrt{\frac{M\times (1-M)}{n}}$

$\Rightarrow SE=\sqrt{\frac{0.4033\times (1-0.4033)}{600}}=0.02$

Putting all the values in the formula,

$\mu = M\pm Z(SE)$

$\mu = 0.4033\pm 1.96(0.02)$

$=0.4033\pm 0.0392$

$=0.4425, 0.3641$

$= 44.25\%,36.41\%$

Answer:

(-1/4, 2)

Step-by-step explanation:

Substitute the given information into the equation and solve for y.

3y +4(-1/4) = 5

3y -1 = 5 . . . . . . simplify

3y = 6 . . . . . . . . add 1

y = 2 . . . . . . . . . divide by 3

The point is (-1/4, 2).

A submarine is cruising 8 meters below the surface. The captain orders a dive of another 17 meters. What is the new cruising dep

swat32

Answer:

25 meters.

Step-by-step explanation:

Given in the question that,

Initial depth of the submarine = 8 meters

After the order of the captain, the submarine was made to dive another 17 meters.

So, the final cruising depth of the submarine can be calculated by adding the initial depth of the submarine and the depth further increased upon the order of the captain.

Thus, final cruising depth of the submarine = 8 + 17 = 25 meters.
