If ground be x axis and helicopter is at y distance then the point should be (x,112)

As we know that

In Q1 and Q2 ,y>0
in Q3 and Q4,y<0

The distance should be written as

+112ft

What is the binomial expansion of (m+2)^4

Alenkasestr [34]

(m+2)⁴ = ((m+2)²)²

= (m² + 4+ 2m)²

= m⁴ + 8 + 4m² + 8m² + 16m + 4m³ .........( (a+b+c)² = a²+b²+c²+2ab+2bc+2ac)

= m⁴ + 8 + 12m² + 16m + 4m³

Consider the following system of equations given in slope-intercept form.

Igoryamba

Option c. The range of window for the data is given as 0 Less-than-or-equal-to x Less-than-or-equal-to 20, 0 Less-than-or-equal-to y Less-than-or-equal-to 20

<h3>How to solve for the range of the data</h3>

We have the equation to be

y = −3x + 17,

and y = 5x - 23

We have to make the two equations to be equal

This would then give us

−3x + 17 = 5x - 23

The next step is to take the like terms

3x - 5x = -23-17

-2x = -40

From you we have to divide by -2

x = 20

The range would be written as

0 ≤ x ≤ 20, 0 ≤ y ≤ 20

Suppose you like to keep a jar of change on your desk. Currently, the jar contains the following: 17 Pennies 10 Dimes 19 Nickels

MatroZZZ [7]

Answer:

0.0688 = 6.88% probability that you reach into the jar and randomly grab a nickel and then, without replacement, a penny.

Step-by-step explanation:

A probability is the number of desired outcomes divided by the number of total outcomes.

Probability of grabbing a nickel:

19 nickels out of 17+10+19+23 = 69 coins, so:

$P(A) = \frac{19}{69}$

Probability of grabbing a penny, considering the first coin grabbed was a nickel:

17 pennies out of 68 coins. So

$P(B|A) = \frac{17}{68} = \frac{1}{4}$

What is the probability that you reach into the jar and randomly grab a nickel and then, without replacement, a penny?

$P(A \cap B) = P(A)P(B|A) = \frac{19}{69} \times \frac{1}{4} = \frac{19}{69*4} = 0.0688$

0.0688 = 6.88% probability that you reach into the jar and randomly grab a nickel and then, without replacement, a penny.
