For the given mean and other values the value of data point will be 131.6.

What is mean?

The arithmetic mean, also known as the arithmetic average or simply the mean or average, is the sum of a set of numbers divided by the total number of numbers in the set. The collection frequently consists of a series of findings from a survey, experiment, or observational study.

The formula for the z-score is

z = (x - μ)/σ

x = data point

μ = mean

σ = standard deviation

Now

Given

Mean=102.8

standard deviation=15.4

z-value=1.87

putting the values in the formula

z = (x-μ)/σ

where x is the data point , μ is the population mean, and σ is the population standard deviation

1.87=(x-102.8)/15.4

Hence,

x=131.6

Answer:

The probability that a student has an A given that the student is female is 8/9.

Step-by-step explanation:

We know that:

P(B) = 9/20 (the probability that a student is female)

P(A and B) = 8/20 (the probability that a student is female and has an A in the class)

We can use the formula:

P(A|B) = P(A and B) / P(B)

So, P(A|B) = 8/20 / 9/20 = 8/9

The percentage of employees in Restaurant B is 28%

The term percentage in math is known as a relative value indicating hundredth parts of any quantity.

Answer:

Yes

Step-by-step explanation:

Pythagoras' theorem states that the square on the hypotenuse of a right triangle is equal to the sum of the squares on the other two sides.

Step-by-step explanation:

what did your teacher want to achieve by the 2 questions that have the same answer ? or is sea level different from the surface of that body of water ? that information would be missing.

the driver descends 15.2 ft per second =

= 15.2/1 ft/s = 15.2 ft/s

after 4.1 seconds the diver descends 15.2 × 4.1 = 62.32 ft.

so, the diver is at that time 62.32 ft under the surface of that body of water.

if sea level is different to the surface of that body of water, then that difference has to be added (when sea level is higher that the water surface) or subtracted (when sea level is below the water surface) to get the the position below or above sea level.

Answer:

  d = 8.24

Step-by-step explanation:

You want the measure of d, the side opposite the 31° angle in the right triangle shown as having a hypotenuse of length 16.

The mnemonic SOH CAH TOA was invented to remind you of the relations between sides and trig functions in a right triangle. In the triangle shown, you have an angle, the side opposite (O), and the hypotenuse (H). The relevant trig relation is ...

  Sin = Opposite/Hypotenuse

Filling in the values shown, this tells you ...

  sin(31°) = d/16

Multiplying by 16 gives the value of d:

  d = 16·sin(31°)

Your calculator can tell you what this value is, rounding it if you want.

The value of d is 8.24.

Additional comment

The other parts of the mnemonic tell you ...

You will notice the flag in the lower left corner of the calculator display tells you the mode is set to Degrees (DEG), rather than radians (RAD) or grads (GRA). This is required in order for sin(31) to be properly interpreted.

The scale factor can alter an object's size, either making it bigger or smaller.

By multiplying the x and y coordinates of the original figure by the scale factor, you may locate locations on the dilated image when a dilation in the coordinate plane has the origin as the centre of dilation. (X, Y) is how the dilation is expressed algebraically for scale factor k.

An object's size can be changed by the scale factor, either making it larger or smaller. To determine a dilated figure's scale factor, use the following simple formula: Scale factor is the product of the old shape's dimension and the new shape's dimension.

By constructing the new function f (x) → f (x), it is possible to dilate a function f (x) in the vertical direction by a scale factor of a. The function's roots and the x-coordinates of any turning points remain unaltered when a function is dilated vertically.

The slope of the given expression is calculated using slope-intercept form. And the answer is 0.

How steep a line is or how much y climbs as x rises is determined by its slope. Slope compares changes to the y-axis, or the vertical axis, with changes to the x-axis, or the horizontal axis. The ratio of any two y values to any two x values can be used to calculate it.

By slope intercept, the standard equation is written as y=mx+b. Here, b is considered as the y-intercept, and m is considered as the slope. Then, the slope is calculated by comparing the given expression with this.

From the given expression, y = -6, we can tell the value of x is zero, the slope is also zero, and the y-intercept b is -6. Therefore, the required answer is 0.

Answer: If 20% of a farmer's harvest had to be given to Pharaoh, and the farmer had to give 40 bushels, we can set up the equation:

(x * 0.2) = 40 bushels

where x represents the number of bushels the farmer harvested. To find the value of x, we can divide both sides of the equation by 0.2:

x = 40 bushels / 0.2

x = 200 bushels

Therefore, the farmer harvested 200 bushels of grain that year.

Given the rule of the Angles on a straight line ∠COD is equal to 30°

Recall that the sum of angles on a straight line is 180°

This means that

3x+94 +x + 18 + 2x-4 = 180°

Let's solve your equation step-by-step.

3x+94+x+18+2x−4=180

Step 1: Simplify both sides of the equation.

3x+94+x+18+2x−4=180

3x+94+x+18+2x+−4=180

(3x+x+2x)+(94+18+−4)=180 (Combine Like Terms)

6x+108 = 180

6x+108=180

Step 2: Subtract 108 from both sides.

6x+108−108=180−108

6x=72

Step 3: Divide both sides by 6.

6x/6 = 72/6

x=12

Since x = 12, therefore,  ∠COD is:

12 +18 = 30°

Thus ∠COD according to the sum of angles on a straight line is = 30°

Step-by-step explanation:

The prior amount is $600.00, the finance charge is $7.50, the new purchases are $90.00, and the payments and credits are each worth $100.00. 597.5 is the new balance.

By doing the identical action on both sides of the =-sign, you can solve equations by using the balance approach. The name is derived from the idea behind it: An (ancient) weighing device known as a balance has a scale, dish, or weighing pan on each side. You place a piece of the equation on each side of the balance.

Even if we change the amounts on either side of the equation by the same number, the balance will remain the same. In order to balance an addition equation, add the side that has no missing numbers first. The opposite side must match this amount. The number that is present on the side with the missing value is then taken, and it is subtracted from your total.

= Purchase - Payments

= 90 - 100

= - 10

New balance   = Previous balance  + Finance charge - Purchase

Answer: The graph represents the system of linear inequalities: {y≤2x−1 y>−2x+3

This can be determined by analyzing the slopes and y-intercepts of the lines represented by the inequalities.

The first inequality, y≤2x−1, represents a line with a slope of 2 and y-intercept of -1. This line will be a solid line because it includes the y=2x-1.

The second inequality, y>−2x+3, represents a line with a slope of -2 and y-intercept of 3. This line will be a dashed line because it does not include the y=-2x+3.

The graph of this system of linear inequalities will be a shaded area that is above the dashed line and below the solid line. This area represents the solution of the system. The other options do not represent the correct system of inequalities.

The exponential equation y = 2500 * 0.76^t models the relationship between the value of a laptop computer (y) and the number of years since it was purchased (t). It shows that each year the value decreases by 24%.

y = 2500 * 0.76^t

Given:

In 2005, a laptop computer was purchased for $2500.

Each year since then, the real value has decreased by 24%.

Let t be the number of years since 2005.

Let y be the value of the laptop computer, in dollars.

We can model this relationship using an exponential function.

Since the real value has decreased by 24% each year, we can use the equation 1 - 0.24 = 0.76 to represent this.

We can then use this to write the exponential function.

y = 2500 * 0.76^t

This equation shows the relationship between y (the value of the laptop computer) and t (the number of years since 2005). The exponential equation y = 2500 * 0.76^t models the relationship between the value of a laptop computer (y) and the number of years since it was purchased (t).
