Answer:

a. -1.60377

b. 0.25451

c. 0.344

d. Option b) 78th

Step-by-step explanation:

The number of pieces in a regular bag of Skittles is approximately normally distributed with a mean of 38.4 and a standard deviation of 2.12.

a)What is the z-score value of a randomly selected bag of Skittles that has 35 Skittles? a) 1.62 b) -1.62 c) 3.40 d) -3.40 e)1.303.

The formula for calculating a z-score is is z = (x-μ)/σ,

where x is the raw score

μ is the population mean

σ is the population standard deviation.

z = 35 - 38.4/2.12

= -1.60377

Option b) -1.62 is correct

b) What is the probability that a randomly selected bag of Skittles has at least 37 Skittles? a) .152 b) .247 c) .253 d).747e).7534. .

z = (x-μ)/σ

Mean of 38.4 and a standard deviation of 2.12.

z = (37 - 38.4)/2.12

= -0.66038

P-value from Z-Table:

P(x<37) = 0.25451

The probability that a randomly selected bag of Skittles has at least 37 Skittles is 0.25451

Option c) .253 is.correct

c) What is the probability that a randomly selected bag of Skittles has between 39 and 42 Skittles? a) .112 b) .232 c) .344 d).457 e).6125.

z = (x-μ)/σ

Mean of 38.4 and a standard deviation of 2.12.

For 39 Skittles

z = (39 - 38.4)/2.12

= 0.28302

Probability value from Z-Table:

P(x = 39) = 0.61142

For 42 Skittles

z = (42 - 38.4)/2.12

= 1.69811

Probability value from Z-Table:

P(x = 42) = 0.95526

The probability that a randomly selected bag of Skittles has between 39 and 42 Skittles is:

P(x = 42) - P(x = 39

0.95526 - 0.61142

0.34384

= 0.344

Option c is.correct

d) What is the percentile rank of a randomly selected bag of Skittles that has 40 Skittles in it? a)82nd b) 78th c) 75th d)25th e)22nd

z = (x-μ)/σ

Mean of 38.4 and a standard deviation of 2.12.

z = (40 - 38.4)/2.12

= 0.75472

P-value from Z-Table:

P(x = 40) = 0.77479

Converting to percentage = 0.77479× 100

= 77. 479%

≈ 77.5

Percentile rank = 78th

The value of a lies between 90.8209 and 91.0116 is 91. Then the correct option is C.

Inequality is simply a type of equation that does not have an equal sign in it. Inequality is defined as a statement about the relative size as well as is used to compare two statements.

The inequality is given as

9.53 < √a < 9.54

On squaring both sides, we have

  9.54² > a > 9.53²

91.0116 > a > 90.8209

Thus, the value of a lies between 90.8209 and 91.0116 is 91. Then the correct option is C.

Answer:

23/10

Step-by-step explanation:

To find the unit rate divide 84 by 36

84 ÷ 36 = 2.3

To convert 2.3 to a faction

2.3 = 2.0 + 0.3

0.3 = 3/10

3/10 + 2 = 2 3/10

2 3/10 = 23/10

Answer:

a)(-3n/4-36)=(-3n/4)+(-36)

-3n/4-36=-3n/4-36

-3n/4+3n/4=-36+36

Answer:

One way is to work backwards and check the factored form (x+6)(x-6) using the FOIL method.

Multiply the first terms, then outside terms, then inside terms, then last terms. Simplify and you will find the extended version of (x+6)(x-6) to be x^2-36, NOT the expression x^2-12x+36.

Answer:

D

Step-by-step explanation:

We simply put each of the points to test

For a point to be correct, if we substitute the x-coordinate value, we should get the value of the y-coordinate

So let’s proceed

(-3,8)

8 = -5(-3) - 7

8 = 15 -7

8 = 8

(-2,3)

3 = -5(-2) - 7

3 = 10 -7

3 = 3

(-1,-2)

-2 = -5(-1) - 7

-2 = 5-7

-2 = -2

(0,-7)

y = -5x -7

y = -5(0) - 7

y = 0-7 = -7

(1,-12)

y = -5(1) -7

-12 = -5 -7

-12 = -12

(2,-17)

-17 = -5(2) -7

-17 = -10-7

-17 = -17

We can see that all the listed points are on the given line

Although all these points lie on the line, we cannot say they represent the set of all solutions

The set of all solutions can simply be represented by the line of the equation

The turtle walks away from the rock at a constant rate.

Step-by-step explanation:

A proportional relationship is one in which the two variables vary directly with each other and can be represented by the equation:

y = kx, where k is the constant of proportionality.

Also, a proportional relationship has a constant rate which is the ratio of the two variables.

A) The equation y = 3x is a proportional relationship because it is in the form y = kx, k =3

B) After 4 minutes, the turtle has walked 12 feet away from the rock.

We cant say that this is a proportional relationship because it may or may not be proportional.

C) The turtle walks for a bit, then stops for a minute before walking again.

It is not proportional

D) The turtle walks away from the rock at a constant rate

This is a proportional relationship because it has a constant rate

Answer:

2400 ml

Step-by-step explanation:

So you find 40% of 6000 ml

[tex]\frac{40 * 6000}{100 * 1}[/tex]

So 6000 times 40 is 240000

Then 100 times 1 is 100 leaving us with:

[tex]\frac{240000}{100}[/tex]

240000 divided by 100 is 2400 ml

So the car burns 2400 ml of oil.

Answer:

x = 3

Step-by-step explanation:

not sure what the term is, but AB is equal to BC because AD = DC

using this, you can make the following equation:

5x - 2 = 7x - 8

subtract 5x from both sides

-2 = 7x - 5x - 8

-2 = 2x - 8

add 8 to both sides

-2 + 8 = 2x

6 = 2x

divide both sides by 2

3 = x

Answer:

160 m/s

Step-by-step explanation:

vi= 10m/s

a= 5om/s*2

t=3 second

vf=?

frist step: find s(distance)

s=vit+1/2 at*2=10m/s x3s +0.5 x50m/s*2 (3s)*2 =30m+225m=255m

second : find vf

s=(vf+vi)/2 xt

vf=2s/t- vi=2(255m)/3s -10 m/s=170 m/s-10m/s=160m/s

Therefore , the final velocity of the car is 160m/s
