Graph image 1 for translation. one unit to the right

rodikova [14]

We use the following reflection rule:
(x, y) = (x + 1, y)
We have then:
M (-3, 1) ---> M '(- 2, 1)
O (1, 4) ---> O '(2, 4)
P (3, -1) ----> P '(4, -1)
Answer:
The new vertices are
M '(- 2, 1)
O '(2, 4)
P '(4, -1)
Graph five (last from left to right) is the correct one.

What is the focus of the parabola

Blizzard [7]

Answer:

(-4,1)

Step-by-step explanation:

The given parabola is

$y = - \frac{1}{4} {x}^{2} - 2x - 2$

When we rewrite in vertex form, we get;

$y = - \frac{1}{4} {(x + 4)}^{2} + 2$

Or

${(x + 4)}^{2} = - 4( y - 2)$

When we compare to:

${(x - h)}^{2} = 4p( y - k)$

We have 4p=-4

This means p=-1

But the vertex is at:

(-4,2)

Since it is a vertical parabola that opens down, the focus is one unit(|p|=1) below the vertex.

Hence the focus is (-4,1)

The workers' union at a particular university is quite strong. About 96% of all workers employed by the university belong to the

vredina [299]

Answer: 0.1699

Step-by-step explanation:

Given: The proportion of all workers employed by the university belong to the workers' union = 0.96

Sample size : n= 5

Binomial probability distribution formula :

$P(X=x)= \ ^nC_xp^x(1-p)^x$

The probability that exactly 4 of the workers interviewed are union members :-

$P(X=4)=^5C_4(0.96)^4(1-0.96)^1\\\\=(5)(0.96)^4(0.04)\\\\=(5)(0.84934656)(0.04)\\\\=0.169869312\approx0.1699$

Required probability = 0.1699
