Answer:

2 and 4

Step-by-step explanation:

2+4 = 6

6/2 = 3

average is sum of number divided by how many numbers there are.

A counterexample to the above rule of the average of two consecutive even numbers being even are 8 and 10.

A counterexample is one that disproves a logic.

The consecutive even numbers of 8 and 10 will give an average of:

= Sum of even numbers / 2

= (8 + 10) / 2

= 18 / 2

= 9

9 is not an even number so we can conclude that 8 and 10 are counterexamples to the above rule.

c) 0.0277

Step-by-step explanation:

Normal Probability Distribution:

Problems of normal distributions can be solved using the z-score formula.

In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the p-value, we get the probability that the value of the measure is greater than X.

(a) ...to the left of 1.8.

p-value of Z = 1.8, which, looking at the z-table, is of 0.9641.

(b) ...to the right of 2.4.

1 subtracted by the p-value of Z = 2.4.

Looking at the z-table, Z = 2.4 has a p-value of 0.9918.

1 - 0.9918 = 0.0082, which is the answer.

(c) ...between 1.8 and 2.4.

p-value of Z = 2.4 subtracted by the p-value of Z = 1.8.

From itens a and b, we have both. So

0.9918 - 0.9641 = 0.0277

Sure it does, it wants you to make the final answer 2 decimal plots away. So if we put in 1, its  33.192. If we put in 3, its 33.336, if we put in 5, 33.48, if we put 9, 33.768. So it has to be 5!

Answer: D) The value of [tex]\sqrt{215}[/tex] is between 14.5 and 15

Step-by-step explanation:

Let's start by taking the squaring these numbers.

[tex]13^2=169\\13.5^2=182.25\\14^2=196\\14.5^2=210.25\\15^2=225[/tex]

215 is in between 14.5 squared and 15 squared. That means its square root will be between 14.5 and 15.5

Answer:

+4, -4

Step-by-step explanation:

There are only two solutions to this equation.

=> x^2 - 16 = 0

=> x^2 - 4^2 = 0  

=> (x+4) (x-4) = 0  {According to a^2 - b^2 = (a+b) (a-b)}

=> x = 4, -4

Answer:

x = 4

x = - 4

Step-by-step explanation:

Method 1: Quadratic Formula

Ignore the A before the ±, it wouldn't let me type it correctly.

[tex]x=\frac{-b±\sqrt{b^{2} -4ac} }{2a}[/tex]

x² - 16 = 0

a = 1

b = 0

c = - 16

[tex]x=\frac{-(0)±\sqrt{0^{2} -4((1)(-16))} }{2(1)}[/tex]

[tex]x=\frac{0±\sqrt{0 -4((1)(-16))} }{2(1)}[/tex]

[tex]x=\frac{0±\sqrt{0 +64} }{2(1)}[/tex]

[tex]x=\frac{0±\sqrt{64} }{2}[/tex]

[tex]x=\frac{0±8 }{2}[/tex]

Two separate equations

One must have a + (positive) and the other will have a - (negative).

[tex]x=\frac{0+8 }{2}[/tex]

[tex]x=\frac{8 }{2}[/tex]

x = 8 ÷ 2

x = 4

[tex]x=\frac{-8 }{2}[/tex]

x = - 8 ÷ 2

x = - 4

Method 2: Factoring

x² - 16 = 0

(x - 4)(x + 4) = 0

Two separate equations

x - 4 = 0

x + 4 = 0

x - 4 = 0

x - 4 + 4 = 0 + 4

x = 4

x + 4 = 0

x + 4 - 4 = 0 - 4

x = - 4

Answer:

Brand B is the better buy.

Step-by-step explanation:

Brand A:

$7.97 / 48 pencils = $0.166/pencil

Brand B:

$9.88 / 72 pencils = $0.137/pencil

Answer: Brand B is the better buy.

Answer: brand B is Cheaper

brand A unit price is 0.17 per pencil

Brand B unit price is 0.14 per pencil

so brand B is cheaper

Step-by-step explanation: the formula to find unit price is Price/Amount of Objects

first find the unit price of brand A: 7.97/48

second find the unit price of brand B: 9.88/72

then compare the one that has the smallest unit price is the cheapest

Answer:

29 m

Step-by-step explanation:

Since Jeff's coach is at the left of the platform and the platform at an angle of elevation of 37° and Jeff's parent's are on the right of the platform with the platform at an angle of elevation of 32°. The line of sight of Jeff's coach, the distance between Jeff's coach and parents and the line of sight of Jeff's parents form a triangle.

Since the platform is 10 m high, it is a perpendicular to the base of the triangle.

This perpendicular bisects the original triangle into two right angled triangles - one on the left and one on the right - with base angle 37° and 32° respectively.

Using trigonometric ratios with the opposite side to each angle the height of the platform from the ground (10 m) and the opposite angles 37° and 32° respectively, then the length of each base is gotten from

tan37° = 10/L and tan32° = 10/L' where L and L' are the lengths of each base of the two right angled triangles respectively.

So, L = 10/tan37° = 10/0.7536 = 13.3 m and L' = 10/tan32° = 10/0.6249 = 16 m.

The length d = L + L' is the distance between Jeff's coach and Jeff's parents

So, d = L + L'

= 13.3 m + 16 m

= 29.3 m

≅ 29 m to the nearest meter.

Note that we do not need the third angle in the triangle which is 100° the angle of separation between Jeff's coach and Jeff's parents which is at the base of the platform.

Answer:

mean = 2

MAD = 3/4

Step-by-step explanation:

1, 3, 2, 2, 1, 3, 3, 1

To find the mean, add up all the numbers and then divide by the number of terms

(1+ 3+ 2+ 2+ 1+ 3+ 3+ 1)/8 = 16/8 = 2

To find the mean absolute deviation

subtract the mean and the number and then take the absolute value, add them together and then divide by the number of terms

|(1-2)| +|(3-2)| +| 2-2| +|2-2|+|1-2| +|3-2|+|3-2| +|1-2|
