Answer: -1.5

Step-by-step explanation:

took the test

The z-score of a bag of almonds weighing 12.2 ounces will be negative 1.5.

The Gaussian Distribution is another name for it. The most significant continuous probability distribution is this one. Because the curve resembles a bell, it is also known as a bell curve.

The z-score is a statistical evaluation of a value's correlation to the mean of a collection of values, expressed in terms of standard deviation.

A machine packages bags of almonds.

The weights of the bags are normally distributed with a mean of 14 ounces and a standard deviation of 1.2 ounces.

Then the z-score of a bag of almonds weighing 12.2 ounces will be

z-score = (x - mean) / SD

z-score = (12.2 - 14) / 1.2

z-score = -1.8 / 1.2

z-score = -1.5

Answer:

a. Yes

b. 3x+7

c. 105 cm

Step-by-step explanation:

a. a(1)+b=10

   a(2)+b=13

when you solve this by elimination or simultaneously: a=3 and b=7

∴ f(x)=3x+7

b. f(x)=3x+7

c. 3(35)+7=112 cm

Answer:It is 5/8 of a pound heavier

Step-by-step explanation:

1 1/4 - 5/8=5/8

Answer:

The larger package is twice as heavy

Step-by-step explanation:

first make 1 1/4 into 5/4 and then multiply the top and the bottom by 2 to get a common denominator of 8. you will end up with 10/8. you can then subtract 5/8 from 10/8, leaving you with 5/8.

Answer:

8 red haired and 42 brown haired

Step-by-step explanation:

I chose a random number to start off with (which is 8) and I multiplied it by 5.

8•5=40 and then you have to add 2, so you get 42.

42+8 = 50

The equation would be (5x+2)+x where 'x' is the number of people with red hair.

Answer:

Degree must be odd.

Step-by-step explanation:

In the end behavior of quadratic functions, the graph will either rise or fall as x increases infinitely. Likewise it will also rise or fall as x decreases infinitely.

Now, when x increases or decreases up to infinity(∞) and f(x) increases up to infinity (∞), it is said to be an even powered function and thus the degree is said to be even.

Similarly, when x increases up to infinity(∞) and f(x) increases up to infinity(∞), it is said to be an odd powered function and degree is odd.

Answer:

The magnitude of the resultant force is: 27.40 pounds

Step-by-step explanation:

Given

[tex]F_1 = 45[/tex]

[tex]F_2 = 50[/tex]

[tex]\theta = 33[/tex]

Required

The magnitude of the resultant vector

To do this, we apply cosine formula

[tex]R^2 = F_1^2 + F_2^2 - 2 * F_1 * F_2 * \cos(\theta)[/tex]

This gives:

[tex]R^2 = 45^2 + 50^2 - 2 * 45 * 50 * \cos(33)[/tex]

[tex]R^2 = 2025+ 2500 - 4500* 0.8387[/tex]

[tex]R^2 = 2025+ 2500 - 3774.15[/tex]

[tex]R^2 = 750.85[/tex]

Take square roots of both sides

[tex]R = \sqrt{750.85\\[/tex]

[tex]R = 27.40[/tex]

Answer:

n = - [tex]\frac{4}{7}[/tex]

Step-by-step explanation:

Given

[tex]\frac{2}{3}[/tex] (1 + n) = - [tex]\frac{1}{2}[/tex] n

Multiply both sides by 6 ( the LCM of 3 and 2 ) to clear the fractions

4(1 + n) = - 3n ← distribute left side

4 + 4n = - 3n ( add 3n to both sides )

4 + 7n = 0 ( subtract 4 from both sides )

7n = - 4 ( divide both sides by 7 )

n = - [tex]\frac{4}{7}[/tex]

Answer:

110 cm²

Step-by-step explanation:

10 x 4 = 40

10 x 5 x 0.5 = 25

10 x 5 x 0.5 = 25

2 x 10 x 0.5 = 10

2 x 10 x 0.5 = 10

add up = 110

5 less would be -5

twice a number would be *2

so the expression would be

Answer:

B) all real numbers expect 4pi+8pi where n is any integer

Step-by-step explanation:

The domain of the function y = tan(x/8) is given by: All real numbers except 4π+8nπ , where n is any integer.

The domain is the set that contains all possible input values for the function.

Since we know that Tangent of an angle is sine of the angle divided by the cosine of the angle, and the cosine is 0 at:

π/2 + nπ

Hence, let a composite tangent function , the domain is given by:

f(x) does not equal to π/2 + nπ

we have that , hence the domain is:

all real numbers except 4π+8nπ

All real numbers except 4π+8nπ, where n is any integer.
