A survey by the national retail federation found that women spend on average r146. On a saturday lunch. Assume the standard deviation is r29. 44. Find the percentage of women who spend less than r190. 00 on a saturday lunch. Assume the variable is normally distributed.

The accumulated interest on the loan given, equals to $778.125.

Also known as compound interest, means the interest on savings calculated on both the initial principal and the accumulated interest from previous periods.

Amount payable equals to:

=  P(1+i/100)*n

= $5,000*(1 + 7.5%)^2

= $5,000 * 1.155625

= $5,778.125

The computation of the accumulated Interest goes as:

= Amount payable on loan - Loan Amount

= $5,778.125 - $5,000

= $778.125

The time it will take to fill the pool if the patch is off while Donnie is filling it, found using the combined filling rate is 6 days.

A flow rate is the fluid volume that passes a specified area within a unit of time.

The number days it takes to fill the pool = 2 days

The number of days it takes for the pool to drain = 3 days

The rate at which the pool fills = [tex]\dfrac{1}{2}[/tex] per day

The rate at which the pool drains = [tex]\dfrac{1}{3}[/tex] per day

The number of days it will take the pool to fill while the patch is off is found from the combined filling rate as follows;

The combined filling rate is [tex]\dfrac{1}{2} -\dfrac{1}{3} = \dfrac{3-2}{6} = \dfrac{1}{6}[/tex]

The combined filling rate can be taken as a combined flow rate.

The combined filling rate for filling the pool while the patch is off is [tex]\dfrac{1}{6}[/tex], which is a 6th of the pool is filled per day, therefore, it takes 6 days to fill the pool while the patch is off.

The equation is C = 6500 + 175S

The total cost to transport 16 tons of sugar is $9300

From the question, we have

C = total cost

S represent the amount of sugar (in tons) transported.

C = 6500 + 175S

total cost to transport 16 tons of sugar = 6500 + 175(16)

= 6500 + 2800

= $9300

The total cost to transport 16 tons of sugar is $9300.

The probability of the complement of this event occurring is  5/6.

What is probability?

Simply put, probability measures how probable something is to occur. We can discuss the probabilities of various outcomes, or how likely they are, whenever we are unsure of how an event will turn out. Statistics is the study of events subject to probability.

The likelihood that a population parameter will be less than a given value when the null hypothesis is true is expressed as the p-value, also known as a probability value or a measure of significance, for a particular statistical model.

Sample space: {1,2,3,4,5,6}

Total number of outcomes=6

Complement of an Event: All outcomes that are NOT the event

In this case:

So, possible outcomes in the complement event:{1,2,4,5,6}

Number of possible outcomes=5

y=2/3x+7 is equation in slope-intercept form of the line that passes through (6, 11). and (2, 25/3). ​

The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.

The slope intercept form of a line is y=mx+b, where m is slope and b is the y intercept.

The slope of line passing through two points (x₁, y₁) and (x₂, y₂) is

m=y₂-y₁/x₂-x₁

The given two points are (6, 11) and (2, 25/3). ​

By using the distance formula, we can see that Luna's time in minutes is 120 minutes.

We know that she went a distance of 10 miles at a rate of 5 miles per hour.

Remember the linear relation:

10 mi = (5mi/h)*t

(10 mi)/(5mi/h) = t

2 h = t

And we want the time in minutes, remember that:

if c ∝ b

Then,

c = kb where k is a constant

When c = 50, b = 3

substituting into the equation above,

The new length of the unstretched hanging-spring is 70 cm.

Hooke's law states that the spring's length change as a result of a compressive or tensile load is directly proportionate to the size of the force placed on the spring. Mathematically,

F = kx

Where;

K is the spring constant, while x represents the spring's length change.

As per the question-

L is the spring's uncompressed length: L = 0.5 m

Weight F1 linked to the spring: F1 = 100 N

First weight's effect on elongation x1: 60 - 50 = 10 = .01 m.

As per the Hooke's law;

F1 = Kx1

K = F1/X1

K = 100 / 0.1

K = 1000 N/m

Spring constant = 1000 N/m.

For the added 100-N block.

F = Kx2

x2 = F/K

x2 = 100 + 100 / 1000

x2 = 0.2m

Answer:

x = 80

Step-by-step explanation:

This shape is a pentagon, and all of the angles in a pentagon always add up to 540. So, using this, we can create an equation, 3x + 300 = 540. we can then use the reverse order of operations to solve this, first subtracting 300 from both sides. this gets us the equation 3x = 240. We then divide 3 from both sides to get x alone and get x = 80.

Answer:

  x = 80°

Step-by-step explanation:

You want the value of x given a pentagon with two angles marked with expressions in x.

The sum of interior angles in an n-gon is 180° × (n -2). For the 5-sided figure shown, the sum of angles is 180° × 3 = 540°.

Using this value, we have ...

  (x +40°) +125° +(x +5°) +(x +50°) +80° = 540°

  3x +300° = 540° . . . . . . simplify

  x +100° = 180° . . . . . . . divide by 3

  x = 80° . . . . . . . . . . . . subtract 100°

The value of x is 80°.
