A 5-pound sack of potatoes is supposed to weigh 5
pounds. However, actual weights of the sacks vary
somewhat. An inspector selects a random sample of 50
sacks of potatoes from the large packaging plant and
weighs them
The inspector will calculate the sample mean and use
that to determine if there is convincing evidence that the
true mean weight of all sacks of potatoes differs from 5
pounds.

Answer:

b = 10

b = 17

Step-by-step explanation:

Hello!

Usually, when you want two different integer solutions, you probably want the quadratic to be factorable.

So what we want to know is that b should be the sum of the factors in 16.

Factors of 16: 1, 2, 4, 8, 16

Factor pairs:

Factor Sums:

These are our possible b-values.

Check:

Let's try 17 first:

Now 10:

And finally, 8:

Since x = 4 is a repetitive integer, we cannot use 8 as a value for b.

The answers are b = 10, and b = 17.

Answer:

Rational

Step-by-step explanation:

Rational numbers are numbers that can be made by dividing two integers, or are the product of two integers. This includes demicals (terminating and repeating), fractions where the numerator and denominator are integers, and perfect squares. This is a terminating decimal, so it is a rational number.

Answer:

height of the peak AB is 40 feet.

Step-by-step explanation:

Answer:

Step-by-step explanation:

Step-by-step explanation:In the figure attached, A is the peak of mountain AB, ED is Tyler who is 6 feet high. Mirror placed at C, is 20 feet from the base of peak. Tyler is 3 feet away from the mirror.1). When Tyler sees the peak in the mirror, angle of incidence " i " and angle of reflection " r " made by incident ray AC and reflected ray EC will be equal.Now we can easily say ∠ r = ∠ E ( Alternate angles )∠ i = ∠ A ( alternate angles)Since ∠ i = ∠ r Therefore, ∠ A = ∠ E∠B = ∠D = 90°and ∠ACB = ∠ECDHence  ΔABC is similar to ΔCDE.2). Corresponding sides of these similar triangles are AB and ED, BC and CD, AC and CE.3). tanE = tanE = 0.5 ∠ E =  degreesNow ∠E = ∠A = 26.57°Therefore, tan(26.57) = 0.5 = AB = Therefore, height of the peak AB is 40 feet.

Volume of sphere is  [tex]\frac{11}{14}[/tex] cubic unit.

The volume of sphere is the measure of space that can be occupied by a sphere. A sphere is a three-dimensional shape that has no edges or vertices.

Volume of sphere = [tex]4\pi r^{2}[/tex]

Given

Radius of sphere = [tex]\frac{1}{4}[/tex] unit

Volume of sphere = [tex]4\pi r^{2}[/tex]

= 4 × [tex]\pi[/tex] × [tex](\frac{1}{4} )^{2}[/tex]

= 4 × [tex]\frac{22}{7}[/tex] × [tex]\frac{1}{16}[/tex]

= [tex]\frac{11}{14}[/tex]

Hence, Volume of sphere is  [tex]\frac{11}{14}[/tex] cubic unit.

Answer:

see explanation

Step-by-step explanation:

using the identity

sin²x + cos²x = 1

consider left side

(cosA - sinA)²

= (cosA - sinA)(cosA - sinA) ← expand using FOIL

= cos²A - sinAcosA - sinAcosA + sin²A

= cos²A + sin²A - 2sinAcosA

= 1 - 2sinAcosA

= right side

The answer will be A number line going from 27 to 37. An open circle is at 32. Everything to the right of the circle is shaded.

The relation between two expressions that are not equal, employing a sign such as ≠ ‘not equal to’, > ‘greater than’, or < ‘less than’.

We have an expression of inequality:-

(-1/2)p < -16

p > 32 . . . . . . multiply by -2; this reverses the inequality symbol

The open circle will be at 32; the line will be shaded for higher values (to the right).

Hence the answer will be A number line going from 27 to 37. An open circle is at 32. Everything to the right of the circle is shaded.

Answer:

Adult tickets sold = 240

Step-by-step explanation:

If student tickets = x,

Adult tickets = 3x + 6

Since the total amount of tickets sold was 318, the equation would be:

x + 3x + 6 = 318

Simplify this:

4x + 6 = 318

4x = 312

x = 78

Student tickets = 78

and so:

Adult tickets = (3 x 78) + 6 = 240

Width = [tex]\frac{3}{4}[/tex] units

Perimeter = 11 [tex]\frac{1}{2}[/tex] units

Step-by-step explanation:

   Area can be found with;

A = L * W

   We will plug in the known values and solve.

A = L * W

3 [tex]\frac{3}{4}[/tex] = 5 * W

(3 [tex]\frac{3}{4}[/tex] ) / 5 = (5 * W) / 5

(3 [tex]\frac{3}{4}[/tex] ) / 5 = W

[tex]\frac{3}{4}[/tex]  units = W

   Perimeter can be found with;

P = 2L + 2W

   We will plug in the known values and solve.

P = 2L + 2W

P = 2(5) + 2([tex]\frac{3}{4}[/tex])

P = 10 + 1 [tex]\frac{1}{2}[/tex]

P = 11 [tex]\frac{1}{2}[/tex] units
