Step-by-step explanation:

sub in each for y and see if the total is bigger than 16

Answer:

y = x^2 + 15x + 56

Step-by-step explanation:

The solutions (where the trinomial = 0) is the factors that will turn the trinomial into 010.

(x + 7)(x + 8) = 0

This means that either -7 will turn the trinomial into 0 or - 8 will.

The trinomial is

x^2 + 8x +  7x + 56 will turn the trinomial to 0.

y = x^2 + 15x + 56 when either - 7 or - 8 is put in for x.

y = (-7)^2 + 15(-7) + 56

y = 49 - 105 + 56

49 + 56 = 105

y = 105 - 105 = 0

y = (-8)^2 - 15(-8) + 56

y = 64 - 120 + 56

y = 120 - 120=  0

No other number will turn the trinomial into 0.

Answer:

Slope B is greater than Slope A

Answer:

C Approximately normal

Step-by-step explanation:

Central Limit Theorem

The Central Limit Theorem estabilishes that, for a normally distributed random variable X, with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]s = \frac{\sigma}{\sqrt{n}}[/tex].

For a skewed variable, the Central Limit Theorem can also be applied, as long as n is at least 30.

In this question:

Sampling distribution of the sample mean is approximately normal, by the Central Limit Theorem. The correct answer is given by Choice C.

Answer:

B - 2 positive unit tiles

Step-by-step explanation:

The dimensions of tile are (x-5) units and (x+2) units.

The factors are the polynomials which are multiplied to produce the original polynomial.

The given expression is x²-3x-10.

Here, x²-5x+2x-10

= x(x-5)+2(x-5)

= (x-5)(x+2)

Therefore, the dimensions of tile are (x-5) units and (x+2) units.

Answer:

6.28 ft

Step-by-step explanation:

The circumference of a circle is given by

C = pi *d  where d is the diameter

C = 3.14 * 2

C = 6.28 ft

Answer:

Step-by-step explanation:

If the radius of the circle is 2mm, the circumference is 4π mm.

Arc length of the quarter circle = π mm.

Perimeter of the quarter circle = arc length + 2 radii = 4π + 4 mm = 16.56 mm

Answer:

The coordinates of a point are a pair of numbers that define its exact location on a two-dimensional plane. Recall that the coordinate plane has two axes at right angles to each other, called the x and y axis. The coordinates of a given point represent how far along each axis the point is located.

Step-by-step explanation:

Answer:

The best value of k for the worker to use is 30.

Step-by-step explanation:

Sample of 120 jars from a set of 3,600.

If the worker will select every kth jar, what is the best value of k for the worker to use?

The best case would be starting at 0 and ending at 3600, finding 120 values, which means that k is given by the division of 3600 by 120. So

[tex]k = \frac{3600}{120} = \frac{360}{12} = 30[/tex]

The best value of k for the worker to use is 30.
