Nostrana [21]
Y - the height of trees after they have been planted;
x - the height of the trees in the pot;
y = x - 12
It a tree is 64 inches tall in the pot:
y = 64 - 12 = 52
The height of a tree is 52 inches.

The standard deviation of a sample taken from population A is 17.6 for a sample of 25. The standard deviation of a sample taken
Dmitry_Shevchenko [17]
The answer is 5.5

The standard deviation (sd or σ) of the sample mean difference is:
sd = √(sd₁²/n₁ + sd₂²/n₂)

For the population A:
sd₁ = 17.6
n₁ = 25

For the population B:
sd₂ = 21.2
n₂ = 30

Hence:
sd = √(sd₁²/n₁ + sd₂²/n₂)
    = √(17.6²/20 + 21.2²/30)
    = √(309.76/20 + 449.44/30)
    = √(15.49 + 14.98)
    = √(30.47)
    = 5.5

Rajiv is building a bookcase a shelf on the bookcase can hold up to 95 pounds of books write an inequality to represent the situ
mihalych1998 [28]
The first thing we must do in this type of problem is first to name the variables that we are going to use to write the inequality.
 We have then:
 b = the weight of books on the shelf.
 The inequality is:
 b <= 95
 answer:
 An inequality to represent the situation is
 b <= 95

Determine if the statement is always, sometimes or never true.
Romashka-Z-Leto [24]

Let

x--------> the measure of the adjacent interior angle

y--------> the measure of an exterior angle at the vertex of a polygon

we know that

The measure of the adjacent interior angle and the measure of an exterior angle at the vertex of a polygon are supplementary angles

so

x+y=180°

<u>Examples</u>

case 1)

<u>In a square</u>

x=90°

so

y=180-90=90°

x=y

In this case

The measure of an exterior angle at the vertex of a polygon equals the measure of the adjacent interior angle

case 2)

<u>an equilateral triangle</u>

x=60°

so

y=180-60=120°

x\neq y

In this case

The measure of an exterior angle at the vertex of a polygon is not equals the measure of the adjacent interior angle

therefore

<u>the answer is</u>

sometimes

Select the two values of x that are roots of this equation.<br> 2x2 + 11x+15= 0
USPshnik [31]

Answer:

The two values of x are -2.5 and -3

Step-by-step explanation:

we have

2x^{2}+11x+15=0

The formula to solve a quadratic equation of the form ax^{2} +bx+c=0 is equal to

x=\frac{-b(+/-)\sqrt{b^{2}-4ac}} {2a}

in this problem we have

a=2\\b=11\\c=15

substitute in the formula

x=\frac{-11(+/-)\sqrt{11^{2}-4(2)(15)}} {2(2)}

x=\frac{-11(+/-)\sqrt{1}} {4}

x=\frac{-11(+/-)1} {4}

x_1=\frac{-11(+)1} {4}=-2.5

x_2=\frac{-11(-)1} {4}=-3

therefore

The two values of x are -2.5 and -3
