Answer:

The difference of the means is 2 times the MAD

Step-by-step explanation:

Mean of data set A = 42

Mean of data set B = 47

MAD of both data sets = 2.5

Difference of their means = 47 - 42 = 5

Thus, the difference of their means = 2 × the MAD

= 2 × 2.5 = 5

Therefore:

The difference of the means is 2 times the MAD

Answer:

x = 80

Step-by-step explanation:

All angles in a triangle add up to 180 degrees.

First, find the angle J:

60+40 = 100, J = 80 because 100+80= 180 degrees.

Now, the two angles on either side of J should also equal 180 degrees. We know that the inner angle is equal to 80 degrees. Thus, the outside angle must equal 100.

x + 20 = 100

x = 80 degrees.

The value of x for the given quadratic expression is x = 5 ± √11.

The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.

Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.

Given expression is 3(x-5)²=33. The value of x will be calculated as,

3(x-5)²=33

(x - 5 )² = 11

(x - 5 )  = ±√11

x = 5 ± √11

Therefore, the value of x for the given quadratic expression is x = 5 ± √11.

The limit is 0.

To find the limit of the function as x approaches infinity, we will use the given expression: lim(x→∞) (x - 3)/(x^2 * 2).
Simplify the expression:lim(x→∞) (x - 3)/(2x^2)

Divide each term by the highest power of x in the denominator, in this case, x^2:
lim(x→∞) [(x/x^2) - (3/x^2)] / (2x^2/x^2). Simplify the expression:lim(x→∞) [(1/x) - (3/x^2)] / 2

Evaluate the limit as x approaches infinity:As x approaches infinity, the terms (1/x) and (3/x^2) approach 0, because the denominator is growing without bound, making the fractions very small.So, the limit is:lim(x→∞) (0 - 0) / 2 = 0/2 = 0

Therefore, the limit of the function as x approaches infinity is 0.

Step-by-step explanation:

Answer:

In the form y=mx+c it is y=-10/7x-45/7

Step-by-step explanation:

We use the formula y-y1=m(x-x1) where m is the slope given by (y2-y1)/(x2-x1)

m=-5-5/-1-(-8)

m=-10/7(plug it into the formula and simplify)

y-5=-10/7(x-(-8)

y-5=-10/7(x+8){multiply through by 7}

7y-35=-10(x+8)

7y-35=-10x-80 (make y the subject)

7y=-10x-80+35

7y=-10x-45(divide through by 7)

y=-10/7x-45/7

Answer:

93

Step-by-step explanation:

The measure of ∠ABC is 124°, given that BX is an angle bisector to ∠ABC, and ∠XBC = 62°. Hence, 3rd option is the right choice.

A ray, segment, or line that splits a given angle into two equal angles is known as an angle bisector. When something is bisected, it is split into two equal sections. In geometry, an angle bisector is a line or ray that divides a triangle into two equal angles.

In the question, we are given that BX bisects ∠ABC, and are asked if the measure of ∠ABC is ∠XBC = 62°.

We assume the measure of ∠ABC to be x°.

As BX bisects ∠ABC, that is, BX is an angle bisector to ∠ABC, we know that ∠XBC = ∠XBA = 1/2 of ∠ABC = 1/2 of x° = (x/2)°.

Thus, ∠XBC = (x/2)°,

or, 62° = (x/2)°,

or, x = 62*2° = 124°.

Thus, the measure of ∠ABC is 124°, given that BX is an angle bisector to ∠ABC, and ∠XBC = 62°. Hence, 3rd option is the right choice.

Answer:

all 3 options are true : A, B, C

Step-by-step explanation:

warning : it has come to my attention that some testing systems have an incorrect answer stored as right answer for this problem.

they say that A and C are correct.

but I am going to show you that if A and C are correct, then also B must be correct.

therefore, my given answer above is the actual correct answer (no matter what the test systems say).

originally the information about the alignment of the point F in relation to point E was missing.

therefore, I considered both options :

1. F is on the same vertical line as E.

2. F is not on the same vertical line as E.

because of optical reasons (and the - incomplete - expected correct answers of A and C confirm that) I used the 1. assumption for the provided answer :

the vertical line of EF is like a mirror between the left and the right half of the picture.

A is mirrored across the vertical line resulting in B. and vice versa.

the same for C and D.

this leads to the effect that all 3 given congruence relationships are true.

if we consider assumption 2, none of the 3 answer options could be true.

but if the assumptions are true, then all 3 options have to be true.

now, for the "why" :

remember what congruence means :

both shapes, after turning and rotating, can be laid on top of each other, and nothing "sticks out", they are covering each other perfectly.

for that to be possible, both shapes must have the same basic structure (like number of sides and vertices), both shapes must have the same side lengths and also equally sized angles.

so, when EF is a mirror, then each side is an exact copy of the other, just left/right being turned.

therefore, yes absolutely, CAD is congruent with CBD. and ACB is congruent to ADB.

but do you notice something ?

both mentioned triangles on the left side contain the side AC, and both triangles in the right side contain the side BD.

now, if the triangles are congruent, that means that each of the 3 sides must have an equally long corresponding side in the other triangle.

therefore, AC must be equal to BD.

and that means that AC is congruent to BD.

because lines have no other congruent criteria - only the lengths must be identical.

Answer:

28.1

Step-by-step explanation:

You can answer questions like this by working backwards.

To do this we can divide 78.2 by 2 and that gets us 39.1

Now we have to subtract 11 from it and that gets us our final answer:

28.1

Answer:

She was thinking of the number 28.1

Step-by-step explanation:

Since we do not initially know what number Natasha was thinking of we have to start with 78.2. From here we have to do the reverse operations of what Natasha did.

So we would divide 78.2 by 2 which gives us 39.1

Then we minus 11 from that and we get 28.1
