Answer:

  (b)  h(x) ≤ 5

Step-by-step explanation:

The maximum vertical extent of the graph is h(x) = 5 at x = 3. The range is all values of h(x) less than or equal to that:

  h(x) ≤ 5

Answer:  Choice B

The range is \(h(x) \le 5\)

==============================================================

Explanation:

If we graph y = x+2, but only draw the line for x values smaller than 3, then we'll end up with the red line shown in the diagram below.

The blue line is the graph of y = -x+8, but it's only drawn when \(x \ge 3\)

The two lines form an upside down V shape. This is an absolute value graph.

The highest point is at the vertex (3,5). The y coordinate is y = 5. This tells us that the largest h(x) can get is h(x) = 5.

Therefore, the range is \(h(x) \le 5\)

This is the same as saying \(y\le 5\) since y and h(x) are both outputs of a function.

Answer:

Step-by-step explanation:

The proportion of Asian Treasure is the difference in price of the mix and Paradise tea, divided by the difference in price of Asian Treasure and Paradise tea. So the amount of Asian Treasure is ...

  (6.00 -5.00)/(7.50 -5.00)(60 ounces) = 24 ounces . . . Asian Treasure tea

The remaining 60-24 = 36 ounces will be Paradise tea.

__

Using an equation

You can get the same result if you define a variable (a) to the amount in ounces of the higher-priced contributor. Then the lower-priced contributor will be in the amount (60-a) ounces. The total cost of the mix is ...

  7.50a +5.00(60 -a) = 60(6.00)

  (7.50 -5.00)a +60(5.00) = 60(6.00) . . . rearrange the left side

  (7.50 -5.00)a = 60(6.00 - 5.00) . . . . . .  subtract 60(5.00)

  a = 60(6.00 -5.00)/(7.50 -5.00) . . . . . . divide by the coefficient of 'a'

Note that this last expression is identical to the one we used above to find the quantity of Asian Treasure tea.

Answer:

2 stickers

Step-by-step explanation:

We multiply his 7 friends by 8 (stickers given to each friend) to get 56 stickers given total.

We subtract 56 from 58 to get 2 stickers remaining for Justin.

Step-by-step explanation:

Justin is giving out 8 stickers to 7 of his friends

To find out how many stickers he passed out, you would need to do 7×8

7×8 = 56

Now you want to subtract 56 from 58 to figure out how many stickers he had left

58 - 56 = 2

Justin is left with 2 stickers

The percentage of people aged 20 to 34 that  have IQs between 125 and 150 of people aged 20 to 34 have IQs between 125 and 150 is 21.94%

Percentage simply means a proportion of the number as a fraction of 100

What percent of people aged 20 to 34 have IQs between 125 and 150?

Let X = Scores on the standard IQ test for the 20 to 34 age group

This implies that  X ~ Normal(x=110, б² = 25)

The z-score probability distribution for the normal distribution is given by;   Z  =   (x-ц)/б ~ N(0,1)

Recall that  population mean = 110 and standard deviation = 25

Now, the percent of people aged 20 to 34 have IQs between 125 and 150 is given by = P(125 < X < 150) = P(X < 150) - P(X  125)

 P(X < 150) = P(  <  ) = P(Z < 1.60) = 0.9452

 P(X  125) = P(    ) = P(Z  0.60) = 0.7258

The above probability is calculated by looking at the value of x = 1.60 and x = 0.60 which has an area of 0.9452 and 0.7258.

Therefore, P(125 < X < 150) = 0.9452 - 0.7258 = 0.2194 or 21.94%

hm this is weird, i thought i answered the question. or maybe they're two different questions? line graph because i said so. i know im so helpful

There are two possible sets of values for r and b that satisfy the condition: r = 1 and b = 2, and r = 4 and b = 3.

Now to find the values of r and b such that there is exactly a 50% chance that two randomly chosen candies will not match, we need to set up the following equation:

(r/b) x ((b-1)/(r+b-1)) + ((b/r) x (r-1)/(r+b-1)) = 1/2

Simplifying this equation, we get:

\(2r^2 - 2rb + 2b^2 - 3r + 3b = 0\)

We can solve for r in terms of b using the quadratic formula:

\(r = (2b ± √(4b^2 - 4(2b^2 - 3b))) / 4\)

Simplifying this expression, we get:

\(r = (b ± \sqrt{(5b^2 - 12b))} / 2\)

Since r and b must be positive integers, we can try small values of b and see if we get integer values for r. For example, if we let b = 2, then:

\(r = (2 ±\sqrt{ (5(2)^2 - 12(2))) } / 2\)

r = (2 ± √4) / 2

r = 1 or 3

So, if there are 2 brown candies and 1 or 3 red candies, there is a 50% chance that two randomly chosen candies will not match.

Similarly, if we let b = 3, then:

\(r = (3 ± \sqrt{(5(3)^2 - 12(3)))} / 2\)

r = (3 ± √21) / 2

Since the square root of 21 is irrational, we cannot get integer values for r in this case. However, we can use a decimal approximation for √21 to get approximate values for r. For example, if we use √21 ≈ 4.58, then:

r ≈ (3 ± 4.58) / 2

r ≈ 3.79 or 0.21

Since r must be a positive integer, the only possible solution is r = 4 and b = 3.

Thus, we have found two possible sets of values for r and b that satisfy the condition: r = 1 and b = 2, and r = 4 and b = 3.

Answer:

A) 0.48

Step-by-step explanation:

The probability that Mrs. Barnes does not check homework if the students take a pop quiz will be 0.77.

Probability means possibility. It deals with the occurrence of a random event. The value of probability can only be from 0 to 1. Its basic meaning is something is likely to happen. It is the ratio of the favorable event to the total number of events.

Mrs. Barnes’s class determined the probability that she will check homework on a randomly chosen day is 0.42.

They also determined the probability that she will give a pop quiz when she checks homework is 0.6, and the probability that she will give a pop quiz when she does not check homework is 0.9.

Then the probability that Mrs. Barnes does not check homework if the students take a pop quiz will be =

P = 0.42 x 0.6 + 0.58 x 0.9

P = 0.252 + 0.522

P = 0.774 ≈ 0.77

Answer:

The ball will not reach a height of 41 meters.

The discriminate is 784

Step-by-step explanation:

You know that the height h of the ball, in meters, at time t seconds is modeled by the function h(t) = - 5*t² + 2*t + 39

To find out if the ball will reach a height of 41 meters, you must calculate the maximum of the function, that is, the highest or highest point on the graph.  That is, the maximum in a function f is the largest value that the function takes.

The vertex is a point that is part of the parabola, which has as its ordinate the maximum value (as in this case) or minimum value of the function. That is, the vertex is the maximum of the function (as in this case) or minimum.

In this case, the maximum of t is obtained by:

\(t=\frac{-b}{2*a}\)

Being a=-5 and b=2 (comparing with a quadratic function of the form: f(x)=a*x² + b*x +c)

\(t=\frac{-2}{2*(-5)}\)

t= 0.2

The maximum height value must be obtained by substituting the previously calculated value of t in the function:

h(0.2) = - 5*0.2² + 2*0.2 + 39

h(0.2)=39.2

So the maximum height the ball will reach is 39.2 meters. The ball will not reach a height of 41 meters.

The discriminate of a quadratic function is:

Δ=b²-4*a*c

In this case, being a=-5, b=2 and c=39, the discriminate is:

Δ=2²-4*(-5)*39

Δ= 4+780

Δ= 784

The discriminate is 784

The first derivative test is the process of analyzing functions using their first derivatives in order to find their extreme point.

No, ball can not reach at height of 41 meters.

Since, The height h of the ball, in meters, at time t seconds is modeled by the function  \(h(t)=-5t^2+2t+39\)

To find maximum height where can ball reach. We use first and second derivative test.

\(h(t)=-5t^2+2t+39\\\\\frac{dh}{dt}=-10t+2\)

Now, equate above derivative to zero.

 \(-10t+2=0\\\\t=1/5\)

Now, find second derivative

\(\frac{d^{2}h }{dt^{2} } =-10\)  , Which is less than zero.

Therefore, at t= 1/5 second , will give maximum height that can ball reach.

So,  h(1/5) = 39.2 meters.

That is, ball can reach at 39.2 meters.

Answer:

basically the even twill not happen as the probability of that is 0

The length of the rectangle is twice its width. If its perimeter is 7 1/3 cm, its length will be 22/9 cm, and the width is 11/9 cm.

Let's assume the width of the rectangle is "b" cm.

According to the given information, the length of the rectangle is twice its width, so the length would be "2b" cm.

The formula for the perimeter of a rectangle is given by:

Perimeter = 2 * (length + width)

Substituting the given perimeter value, we have:

7 1/3 cm = 2 * (2b + b)

To simplify the calculation, let's convert 7 1/3 to an improper fraction:

7 1/3 = (3*7 + 1)/3 = 22/3

Rewriting the equation:

22/3 = 2 * (3b)

Simplifying further:

22/3 = 6b

To solve for "b," we can divide both sides by 6:

b = (22/3) / 6 = 22/18 = 11/9 cm

Therefore, the width of the rectangle is 11/9 cm.

To find the length, we can substitute the width back into the equation:

Length = 2b = 2 * (11/9) = 22/9 cm

So, the length of the rectangle is 22/9 cm, and the width is 11/9 cm.
