A bag of baby carrots can weigh 2929.54 ounces to be​ not repackaged.

To find the weight threshold for bags of baby carrots that need repackaging, we need to find the weight value corresponding to the 95.5th percentile of the normal distribution. This corresponds to the value that separates the upper 4.5% of the distribution (since 100% - 4.5% = 95.5%).

We can use the z-score formula to find the z-score corresponding to the 95.5th percentile, and then use that z-score to find the corresponding weight value.

The z-score formula is:

z = [tex]\frac{x - \mu}{\sigma}[/tex]

where:

x - value we're interested in (weight threshold)

[tex]\mu[/tex] - mean of the distribution = 2929

σ - standard deviation of the distribution = 0.33

z - z-score corresponding to the percentile

First, let's find the z-score corresponding to the 95.5th percentile using a standard normal distribution table or a calculator. For a normal distribution, the z-score corresponding to the 95.5th percentile is approximately 1.645.

Now, we can rearrange the z-score formula to solve for x:

x = [tex]\mu[/tex] + z σ

Plugging in the values:

x = 2929 + 1.645 × 0.33

x = 2929 + 0.54285

x = 2929.54

Therefore, the most a bag of baby carrots can weigh and not need to be repackaged is approximately 2929.54 ounces.

The question is:

The weights of bags of baby carrots are normally​ distributed, with a mean of 2929 ounces and a standard deviation of 0.33 ounces. The bags in the upper​ 4.5% are too heavy and must be repackaged. What is the most a bag of baby carrots can weigh and not need to be​ repackaged?

The hot water faucet cannot fill the tub on its own.

To find the time it takes for the hot water faucet to fill the tub on its own, we need to determine the time it takes for the cold water faucet and the hot water faucet together to fill the tub. Let's assign variables:

We can create the equation:

C + H = T

Substituting the known values and solving for H:

18 + H = 8

H = -10

Since a negative time doesn't make sense in this context, it means that the hot water faucet cannot fill the tub on its own. Therefore, the question is not solvable.

The expression solved for z is:

z = (4/3)*(y + w)

Here we have the expression:

y + w - 3/4z = 0

And we want to solve it for z, which means that we need to isolate z on one side of the expression.

If we add (3/4)z in both sides we get:

y + w = (3/4)z

Now if we multiply both sides by (4/3).

(4/3)*(y + w) = (4/4)*(3/4)z = z

Then we got:

z = (4/3)*(y + w).

Thus, the expression is solved for z.

Ratio of red apples to all apples in the basket is 9:14 and  ratio of red apples to green apples 9:5

A ratio is an ordered pair of numbers a and b, written a / b where b does not equal 0.

The number of apples are in basket =14

The number of green apples in basket = 5

The number of red apples are 14-5=9

As we know that 5 in 14 apples are green and remaining apples red.

So the red apples = 14-5=9

the ratio of red apples to all apples in the basket is 9:14

the ratio of red apples to green apples 9:5

Hence ratio of red apples to all apples in the basket is 9:14 and  ratio of red apples to green apples 9:5

To solve this question:

Doing this, we get that: [tex]c = -\frac{35}{4}[/tex]

Solving a quadratic equation:

Given a second order polynomial expressed by the following equation:

[tex]ax^{2} + bx + c, a\neq0[/tex].

This polynomial has roots [tex]x_{1}, x_{2}[/tex] such that [tex]ax^{2} + bx + c = a(x - x_{1})*(x - x_{2})[/tex], given by the following formulas:

[tex]x_{1} = \frac{-b + \sqrt{\Delta}}{2*a}[/tex]

[tex]x_{2} = \frac{-b - \sqrt{\Delta}}{2*a}[/tex]

[tex]\Delta = b^{2} - 4ac[/tex]

x²+x+c=0

Comparing with the standard second order equation, which is:

[tex]ax^2 + bx + c = 0[/tex]

We get that:

[tex]a = 1, b = 1[/tex]

Finding the roots:

[tex]\Delta = b^{2} - 4ac = 1^2 - 4(1)(c) = 1 - 4c[/tex]

[tex]x_{1} = \frac{-1 + \sqrt{1 - 4c}}{2}[/tex]

[tex]x_{2} = \frac{-1 - \sqrt{1 - 4c}}{2}[/tex]

Difference of 6

Thus:

[tex]x_1 - x_2 = 6[/tex]

[tex]\frac{-1 + \sqrt{1 - 4c}}{2} - \frac{-1 - \sqrt{1 - 4c}}{2} = 6[/tex]

[tex]-\frac{1}{2} + \frac{\sqrt{1 - 4c}}{2} + \frac{1}{2} + \frac{\sqrt{1 - 4c}}{2} = 6[/tex]

[tex]\frac{2\sqrt{1 - 4c}}{2} = 6[/tex]

[tex]\sqrt{1 - 4c} = 6[/tex]

[tex](\sqrt{1 - 4c})^2 = 6^2[/tex]

[tex]1 - 4c = 36[/tex]

[tex]-4c = 35[/tex]

[tex]4c = -35[/tex]

[tex]c = -\frac{35}{4}[/tex]

Thus, [tex]c = -\frac{35}{4}[/tex] is the value.

Final answer:

Leila's total pay after working a certain number of hours is found by the equation p = 9h, where p represents the total pay and h represents the hours worked.

Explanation:

Leila's total pay p after working h hours at a rate of $9 per hour can be represented by the equation p = 9h. This equation indicates that for every hour Leila works, she earns $9. Therefore, to find her total pay, you would multiply the number of hours she has worked (h) by her hourly wage ($9).

Without the necessary figures or context, we cannot make a correct comparison between segment lengths s and t. The question lacks clarity and detail, therefore the answer is that no comparison can be made.

The geometrical figures and the comparison of segment lengths within these figures. Given the Pythagorean theorem and the details about forces and lines, we have information that could pertain to geometry, specifically to properties of triangles and the comparison of segment lengths or areas. However, without the actual figures or a clear indication of the context involving s and t, we cannot provide an accurate comparison between them. This implies that the answer would be D. No comparison can be made.

It is possible that s and t are referring to the lengths of sides in a triangle, but this question, as presented, lacks the clarity and detail required to make a precise calculation or comparison. For example, in the case of two segments being hypotenuse and side of right triangles, if we knew the lengths of the other sides, we could apply the Pythagorean theorem to find the relationship between s and t. But without this information or a clear diagram, we cannot conclude anything about the relationship between s and t.

S = Strawberry wafer packets

c = chocolate wafer packets

s +c = 22

B)

 s + c = 22

s = 22-c

3.00(22-c) + 1.00c = 30.00

66.00 - 3.00c +1.00c = 30.00

66.00 -2.00c =30.00

Answer:

B. 1.43

Step-by-step explanation:

Because tan (180-θ)=-tan θ

[tex]tan (145) = tan (180 -35)= -tan 35 = -\frac{1}{1.43}\\tan 35 =\frac{1}{1.43}[/tex]

Because tan (90+θ) = -cot θ

tan (-125) can be written as:

[tex] tan(-125)=-tan (125) = - tan (90+35) = cot 35[/tex]

tan θ x cot θ =1

⇒tan 35 x cot 35 = 1

⇒[tex]\frac{1}{1.43} \times cot 35 =1 \\ cot 35 = 1.43[/tex]

⇒[tex] tan(-125)= cot 35 = 1.43[/tex]

The minimum of G(x) is -2 and of F(x) is 4 So, G(x) has the smallest minimum y-value.

The function G(x) is a sine function. The sine function, sin(x), has a range of -1 to 1. The minimum value of sin(x) is -1. Since G(x) = 2 sin(x - π), we multiply the minimum value of sin(x) by 2.

The minimum value of sin(x - π) is:

sin(x - π) = -1

Thus, the minimum value of G(x) is:

2 * (-1) = -2

To find the minimum value of a quadratic function, we use the vertex formula, x = -b / 2a. For F(x), a = 3, b = 12, and c = 16.

The x-coordinate of the vertex is:

x = -12 / (2 * 3) = -12 / 6 = -2

Substitute x = -2 into the function to find the minimum y-value:

F(-2) = 3(-2)² + 12(-2) + 16

F(-2) = 3(4) - 24 + 16 = 12 - 24 + 16 = 4

An equation in slope intercept form, passes through (-1,-10), parallel to y=7 is y = -10 .

The slope of a line is defined as the change in y coordinate with respect to the change in x coordinate of that line. The slope of a line is the measure of the steepness and the direction of the line.  

The slope intercept formula y = mx + b is used when you know the slope of the line to be examined and the point given is also the y intercept (0, b). In the formula, b represents the y value of the y intercept point.

According to the question

An equation in slope intercept form,

passes through (-1,-10), parallel to y = 7

now,

When line is y = 7

that means , x = 0

and it is also a horizontal line , i.e slope (m) = 0

As, Parallel lines have same slope .

By using slope intercept formula for  (-1,-10)

y = mx + b

substituting the value

-10 = 0 + b

b = -10

Therefore, putting values in general equation of slope intercept for any point

y = mx + b

y = -10  

Hence, an equation in slope intercept form, passes through (-1,-10), parallel to y=7 is y = -10 .
