Nineteen less than 6 times a number is the same as 16 more than the number. The equation is The solution is x -7 7.​
Crank

Answer:

The number is 7

Step-by-step explanation:

let the said number be x

Nineteeen less than 6 times a number;

6x - 19

equals; 16 more than the number; this is 16 + x

Thus;

6x - 19 = 16 + x

6x-x = 16 + 19

5x = 35

x = 35/5

x = 7

Company A offers a starting salary of $28000 with a raise of $3000 each year, Company B offers a starting salary of $36000 with
telo118 [61]
We can conclude that both will intersect at a certain angle, depending on this algorithm I created.

28000 + 3000x = 36000 + 2000x

The f(x) intercept for g(x) is = 9 and -9

If you square this by light, the arithmetic of 9x+5x=21s(x)

Thus we can simply and get 11 years.

In the diagram, mZXYZ = 115° and mZWXY = 45°.
Allushta [10]

Step-by-step explanation:

mXYZ+mXYW=180°(being straight angle)

mXYW =180-115

mXYW=65

now,

mXWY+mWXY+mXYW=180°(sum of angle of triangle)

mXWY=180-110

mXWY=70°

hope it helps.

A random sample of 45 door-to-door salespersons were asked how long on average they were able to talk to the potential customer.
dimulka [17.4K]

Answer:

b.  =8.5+1.96*3/SQRT(45), and =8.5-1.96*3/SQRT(45)

Step-by-step explanation:

Sample size (n) = 45

Sample mean (M) = 8.5 minutes

Variance (V) = 9 minutes

Z-score for a 95% confidence interval (z) = 1.96

A confidence interval is defined by the following expression:

M\pm z\sqrt{\frac{V}{n} }

Applying the given data:

8.5\pm 1.96\sqrt{\frac{9}{45} }\\8.5\pm 1.96\frac{3}{\sqrt 45}

Writing in Excel statements, the limits of the interval would be

=8.5+1.96*3/SQRT(45), and =8.5-1.96*3/SQRT(45)

Therefore, the answer is alternative b.
