Answer:

A. \log _2\left(6\right)+\log _2\left(7\right)=\log _2\left(42\right)

Step-by-step explanation:

To express \log _2\left(6\right)+\log _2\left(7\right) as a single logarithm you must apply the log rule:

\log _c\left(a\right)+\log _c\left(b\right)=\log _c\left(ab\right)

So,

\log _2\left(6\right)+\log _2\left(7\right)=\log _2\left(6\cdot \:7\right)

Multiply the numbers: 6\cdot \:7=42

\log _2\left(6\right)+\log _2\left(7\right)=\log _2\left(42\right)

What is the equation of the graph shown?​
OlgaM077 [116]

<em>Greetings from Brasil...</em>

As we have a line, the function will be given by the expression:

F(X) = AX + B

where

<em>A = ΔY/ΔX</em>

<em>B = where the line intersects the Y axis</em>

Looking at the graph we have already concluded that

B = - 3

A = ΔY/ΔX

A = (5 - 3)/(4 - 3)     see attached picture

A = 2

So,

F(X) = AX + B

<h2>F(X) = 2X - 3</h2>

The mean of a population being sampled is 64, and the standard deviation is 6. If the sample size is 50, the standard error of t
Serjik [45]
Given:
mean = 64
standard deviation = 6
sample size = 50

Standard error of the sample mean = standard deviation / √sample size

Standard error = 6 / √50 = 6/7.07 =<span> 0.85</span>

PLEASE HELP!!<br>Write an inequality, in slope-intercept form, for the graph below. ​
Bond [772]

Ok, so we know one point is (4,2) and the other is (-4, 0)

Slope: -2/-8 = 1/4

y ? 1/4x + b

0 = -1 + b

b = 1

y < 1/4x + 1
