Answer:

the populations from which the samples were drawn have different standard deviations

Step-by-step explanation:

Given that the assumption of homogeneity of variance is the same as the assumption of the independent samples t-test which asserted that all comparison groups possess the same variance

Therefore, if the homogeneity of variance assumption is violated in an independent groups t-test, this means "the populations from which the samples were drawn have different standard deviations."

If the base angles of a trapezoid are congruent, what can be said about the diagonals of the trapezoid
Schach [20]

9514 1404 393

Answer:

  the diagonals are congruent

Step-by-step explanation:

If the base angles of a trapezoid are congruent, it is an isosceles trapezoid. It will be symmetrical about its center line. Each half of the trapezoid is identical (mirror image) to the other half. The diagonals are the same length.

NISA [10]

Answer:

a. x + 64 = 70

b. x = 6

Step-by-step explanation:

Let the fifth number be x.

\implies \: mean =  \frac{sum \: of \: the \: numbers}{total \: numbers}  \\  \\  \implies \: 14 =  \frac{12 + 17 + 24 + 11 + x}{5}  \\  \\ \implies \: 14 =  \frac{64 + x}{5}  \\  \\ \implies \: 14 \times 5 =x+  64  \\  \\\implies \:\purple{\bold{x+ 64 =70}}\\(this \: is \:the \: required\: equation)\\  \\ \implies \: x= 70   - 64  \\  \\ \implies \: x = 6

Oksanka [162]

Answer:

x = 2, and 6

x = 2 , 6

Step-by-step explanation:

The quadratic function to analyze is: y = -x^2+8x-12

In order to find where the corresponding parabola intercepts the x axis, we set it equal to zero (y = 0):

y = -x^2+8x-12\\0 = -x^2+8x-12\\x^2-8x+12=0

This equation is easy to solve by factoring. We look for a air of integer numbers whose product equals the constant term "12", and whose combinig renders the coefficient of the middle term of the trinomial "-8".

The two such numbers are "-2" and "-6". We use them to split the middle term, and then solve by factoring by grouping:

x^2-8x+12=0\\x^2-2x-6x+12=0\\(x^2-2x)+(-6x+12)=0\\x(x-2)-6(x-2)=0\\(x-2)(x-6)=0

For the product of two factors to render zero, we need either one to be a zero.This means that (x-2)=0 (that is x = 2), or (x-6)=0 (that is x = 6).

So, there are two x-intercepts: x= 2, and 6
