Answer:

18 eggs are still good.

Step-by-step explanation:

If 40% was broken then 60% are still good.

30(.6) = 18

Answer: 18 eggs were not broken and considered good.

Step-by-step explanation:  30 x 40% is the amount of eggs that were broken.

30 x 60% would be the amount of eggs that were still good.

This is becuase the total percentage must add up to be 100% between good eggs and broken eggs.

30 x .60 = 18   So 18 eggs were good

30 x .40 = 12, so that was the number of eggs that were broken

You could have done this problem two ways.  Either calculate the broken eggs and subtract from the total.  30-12 = 18, or you could have just calculated the correct amount from figuring the percentage of eggs that were good from the beginning.  

Answer:

Using a class size of 6.

Range = Highest value - Lowest value = 100 - 1 = 99

No. Of class = range/class size = 99/6 = 16.5 ~ 17/classes.

Upper-class limit of class (1) = Lower class limit of class (1) + class size - D

=> 1 + 6 - 1 = 7 - 1 = 6

The reciprocal of 3 7/8 is 8/31.

To find the reciprocal of a number, we invert the fraction by swapping the numerator and denominator.

Let's calculate the reciprocal of 3 7/8.

First, we need to convert the mixed number into an improper fraction. To do this, we multiply the whole number (3) by the denominator (8) and add the numerator (7). This gives us:

3 7/8 = (3 x 8 + 7) / 8 = 31/8

Now, to find the reciprocal, we invert the fraction:

Reciprocal of 31/8 = 8/31

Therefore, the reciprocal of 3 7/8 is 8/31.

The solution of the equation for the values of r is -2 and 2.

For the expression

2+ I5rI = 12

Subtract both side by 2

2 + I5rI -2 = 12 - 2

I5rI = 10

Open the modulus function as;

Solve for each term

-5r = 10

Divide both side by -5,

r = 2

Now,

5r = 10

Divide both side by 5,

Answer: 1/2

Step-by-step explanation:

If we have an equaton in a standard form, that is y = mx + b, our slope is m (the coefficient of x). So, let's transform 3x - 6y = 144 into the standard form.

3x - 6y = 144

-6y = - 3x + 144

y = -3/(-6)x - 144/6

y = (1/2)x - 24

As I mentioned above, the slope is the coefficient of x. Here our slope is 1/2.

The prices p that would yield a revenue of 7110 dollars are;

Lowest price = $0.895

Highest price = $119.105

We are told that the total revenue obtained by producing and selling x units is given by; R = xp.

Now, we are told that the demand equation for a certain product is given by p = 120 - 0.015x.

where;

p is the unit price (in dollars) of the product.

x is the number of units produced.

At a revenue of $7110, we will have;

(120 - 0.015x)x = 7110

120x - 0.015x² = 7110

0.015x² - 120x + 7110 = 0

Using quadratic equation calculator, we have;

x = 59.695 and 7940.305

Thus;

Lowest price = 120 - 0.015(7940.305) = $0.895

Highest price = 120 - 0.015(59.695) = $119.105

The values that a function approaches for the specified input values are known as limits in mathematics. Limits are essential to calculus and mathematical analysis because they help define concepts like integrals, derivatives, and continuity.

The probability that sunflower will be less than 136 cm tall is 0.9332.

The area of mathematics known as probability deals with numerical representations of the likelihood that an event will occur or that a statement is true.

From the information, the biologist measures a large sample of sunflowers and creates a probability distribution and the distribution is normal in shape with a mean 112 cm and a standard deviation 16 cm.

It should be noted that the following can be deduced:

Mean = 112

Standard deviation = 16

Sunflower should be less than 136. This will be x < 136.

Therefore, the probability will be;

P(X < 136)

= P(Z < [(number - mean) / standard deviation)]

= P(Z < [136 - 112)/16]

= P(Z < 1.50)

= 0.9332

It should be noted that the probability is gotten by looking at the value of x in the z table.

Answer:

Equation of line is given as y = mx + c, where m is the gradient and c is the y-intercept.

Find gradient of the line first.

Formula of gradient is given as y2-y1 ÷ x2-x1 or y1-y2 ÷ x1-x2, where x and y are the coordinates of the points.

Gradient = (-3-0) ÷ (-2-5) = 3/7

Eqn is y = 3/7x + c

Substitute either one of the coordinates into the equation to find c.

0 = 3/7(5) + c

c = -15/7

Hence, the equation of the line is y = 3/7x - 15/7

A function is an equation defining the relationship between input and output variables

(A, 2A)

A continuous function is one in which a continuous variation in the input values produces a continuous variation in the output. Therefore, a continuous function does not have discontinuity and it has a defined output within the interval in which it is contagious

A discrete function is one that have input values and output only at specified points, such that the function does not have inputs, and therefore, outputs at certain points.

The points in the scatter plot of the first graph are separate and not linked, such that the function is not contagious between any two x–values, which gives;

The function is a discrete function

The domain, which is the set of possible x–values is; {x| x = -8, -2, 3, 6}

The range is {y|y = 5, 4, -2, 7, }

The line joining the points on the second graph, indicates that the graph has values for all input or x–values

Therefore, the function of the graph is a continuous function
