A company director investigated whether there is a difference in the mean number of overtime hours worked each week by employees

assigned to two different managers. Each manager, A and B, manages 100 employees. Random samples of 35 employees from manager A and 40 employees from manager B were selected. The number of overtime hours worked was recorded for the 75 employees each week. Have the conditions been met for inference with a confidence interval for the difference in the population means?

Which equation represents a line that passes through (–2, 4) and has a slope of StartFraction 2 Over 5 EndFraction.? y – 4 = (x
Leona [9271]

In this problem, the point-slope form of a line is defined as:

(y-y_ {0}) = m (x-x_ {0})

Where:

(x_ {0}, y_ {0}): represents a point on the line,

and m stands for the slope.

Given the details:

(x_ {0}, y_ {0}): (-2,4)\\m = \frac {2} {5}

Substitute the values:

y-4 = \frac {2} {5} (x - (- 2))\\y-4 = \frac {2} {5} (x + 2)

Thus, the equation of the line is:

y-4 = \frac {2} {5} (x + 2)

Answer:

y-4 = \frac {2} {5} (x + 2)

On his math test, Balavan wrote that a four-sided polygon that has at least two right angles must be a rectangle or a square. De
zzz [9093]
A trapezoid can indeed be a quadrilateral with only two right angles, hence Balavan's assertion is incorrect. Denna is correct as having three right angles implies the fourth angle must also be a right angle, leading to either a square or a rectangle.

Triangle E F G is shown. Which statements regarding Triangle E F G are true? Select three options. E F + F G greater-than E G E
zzz [9093]

Answer:

The correct statements are options 1 (E F + F G > E G), 2 (E G + F G > E F), and 5 (E G + E F < F G).

Step-by-step explanation:

We have triangle EFG.

For any triangle with sides a, b, and c, these inequalities hold:

a+b>c\\ \\a+c>b\\ \\b+c>a

Specifically for triangle EFG:

  • EF+FG>EG;
  • EG+GF>EF;
  • FE+EG>FG.

Thus, the true statements are options 1, 2, and 5.

Statements 3 and 4 are incorrect.

Mario has a business selling muffins. Let x be the price of a muffin. Then, the profit P for Mario’s business is given by p(x)=-
tester [8842]
To achieve a positive profit p(x)>0, we start with:
-100 x^{2} +350x-150 \ \textgreater \ 0

Next, we solve for x:
-2 x^{2} +7x-3 \ \textgreater \ 0

The parameters are:
a = -2
b = 7
c = -3

We will apply the quadratic formula:
x_{1} = \frac{-b+ \sqrt{ b^{2}-4ac } }{2a} \\ \\ x_{2} = \frac{-b- \sqrt{ b^{2}-4ac } }{2a} \\ \\ x_{1} = \frac{-7+ \sqrt{ 49-24 } }{-4} = \frac{-7+5 }{-4} = \frac{-2 }{-4} = \frac{1}{2} \\ \\ x_{2} = \frac{-7- \sqrt{ 49-24 } }{-4} = \frac{-7-5 }{-4} = \frac{-12 }{-4} = 3

This yields two results—one a fraction, the other a whole number. We focus on the whole number since the muffins sold must be a complete unit. Thus we conclude:
x>3
