Which expressions are equivalent to 4^{-2} \cdot 7^{-2}4 −2 ⋅7 −2 4, start superscript, minus, 2, end superscript, dot, 7, start

PolarNik [594]

Answer:

Step-by-step explanation:

Given the expression 4^{-2}•7^{-2}. The following expression are equivalent to given expression on simplification.

Generally from indices, a^-b = 1/a^b. Applying this to the given expression we have:

4^{-2}•7^{-2} = 1/4^2 • 1/7^2

= 1/(4×4) • 1/(7×7)

= 1/16 • 1/49

= 1/(16×49)

= 1/784

A and B are two events.

maria [59]

Answer:

0.8

Step-by-step explanation:

We can solve P(A or B) by using the following:

$P(AorB)=P(A)+P(B)-P(AandB)$

Since we know P(A) = 0.6, P(B) = 0.3 and P(A and B) = 0.1 we obtain:

$P(AorB)=0.6+0.3-0.1=0.8$

1. Choose the correct simplification of the expression −5x2(4x − 6x2 − 3).

1) <span>30x4 − 20x3 + 15x2

This is the answer to 1. Don't forget to rearrange the terms in ascending order. That can trip people up.

2) </span><span>x3 + 8x2 + 13

Don't forget to check the terms sign. The subtraction symbol switches them all. </span>

The required linear equation is given by y=10x + 15

The data collected by Harvard Business School plots the linear relationship of business startup success vs. Time.

<h3>What is Statistic?</h3>

The statistic is the study of mathematics which deal with relations between comprehensive data.

As clearly, points represents on graph startup success vs Time
part of a straight line
so we take two points on graph at (1,25), (2,35)
now equation of line

$y-y_1=\frac{y_2-y_1}{x_2-x_1} (x-x_1)$
= $y-25=\frac{35-25}{2-1} (x-1)$
$y=10x+15$

Thus, The required expression is given by y=10x + 15 which show the relation ship between startup success Vs time
