A 48.5 The answer is A because you would put the numbers in order from least to greatest, find the median, then find the median of the other two sets.

Answer:

A ) First quartile (Q1): 48.5.

Step-by-step explanation:

Given : 51, 42, 46, 53, 66, 70, 90, 70 .

To find : What is the first quartile (Q1) of the data set?

Solution : We have given 51, 42, 46, 53, 66, 70, 90, 70 .

Arrange the data least to greatest

42 ,46, 51, 53, 66, 70, 70, 90.

First half is 42 ,46, 51, 53,

Second half is 66, 70, 70, 90.

First quartile (Q1): $\frac{46 +51}{2}$ .

First quartile (Q1): $\frac{97}{2}$ .

First quartile (Q1): 48.5

Therefore, A ) First quartile (Q1): 48.5.

The data below shows the average number of text messages sent daily by a group of people: 7, 8, 4, 7, 5, 2, 5, 4, 5, 7, 4, 8, 2,

It all depends. You've given us an incredibly vague question.

The outlier could be a number that's low or quite high. Also, outliers
shouldn't really contribute towards the value of the mean, median or
range related to a group of data.

They are called outliers because they are bizarre results or numbers
and should be detached from groups of data. Outliers by definition
are abnormalities or anomalies.

I'd say outliers don't really change anything, unless you actually want
to give them credibility or weight.

Large outliers can inflate the value of means, medians and ranges.

Small outliers will invariably deflate the value of means and medians.

Please answer this question I need it i. Vertex and standard form.

Brums [2.3K]

Equation :

This parabola is facing downwards and highest point of the parabola is it's vertex.

Highest point is (-2,2)

so the vertex is (-2,2)

The graph is passing through (-1,0)

Equation in vertex form is

$y = a(x - h) {}^{2} + k$

$0 = a( - 1 + 2) {}^{2} + 2 \\ 0 =a (1) {}^{2} +2 \\ 0 = a + 2 \\ a = - 2$

Substitute back in Equation

$y = - 2(x + 2) {}^{2} + 2$

the graph has two x intercepts -1 and -3

that means (x+1) and (x+3) are the factors

multiply factors to get the equation in standard form

$-2(x + 1)(x + 3) = 0 \\ -2(x {}^{2} + x + 3x + 3) = 0 \\ -2( x {}^{2} + 4x + 3) = 0$

-2x^2-8x-6=0

Please Answer ASAP <br> Math Question

MArishka [77]

If you were to factor you would do what my teacher likes to call reverse foil so it would look like this (x-9)(x+4) so what you do is you brainsrorm to see what multiplies what to get that and 9*4=36 so that is how you factor -36 to find the -9 Hope this helps if I'm correct if not I will try to find the answer
