First, we need to total the number of students that took the test:
1 student got between 1-20%
3 students got between 21-40%
5 students got between 41-60%
8 students got between 61-80%
8 students got between 81-100%
Therefore, the sum of the students is 1+3+5+8+8 = 25 students in total
There were 16 students who got a 61% or above, so the fraction of students that got a 61% or higher is 16/25. Convert this to a decimal, and we get 0.64. To convert from decimal to percent, multiply the decimal by 100%, and the final answer is 64% of students got a 61 or better on the exam.

What is the relationship between the degree of a function and the degree of the derivative?

Over [174]

Answer:

Graphing the derivative with the function can illustrate how to find these turning points. The function is increasing exactly where the derivative is positive, and decreasing exactly where the derivative is negative. On the graph of the derivative find the x-value of the zero to the left of the origin.

A poker hand consisting of 7 cards is dealt from a standard deck of 52 cards. Find the probability that the hand contains exactl

77julia77 [94]

Answer:

The probability is 2,010,580/13,378,456

Step-by-step explanation:

Here is a combination problem.

We want to 7 cards from a total of 52.

The number of ways to do this is 52C7 ways.

Also, we know there are 12 face cards in a standard deck of cards.

So we are selecting 3 face cards from this total of 12.

So also the number of cards which are not face cards are 52-12 = 40 cards

Out of all these 40, we shall be selecting exactly 4. The number of ways to do this 40C4

Thus, the required probability will be;

(40C4 * 12C3)/52C7 = (91,390 * 220)/133,784,560

= 20,105,800/133,784,560 = 2,010,580/13,378,456

Answer:

slope = 2

Step-by-step explanation:

Pick two points to find the slope. (1, 2) and (3, 3)

From the left (1, 2) to (3, 3), it goes up 2 units and to the right 1 unit.

We can plug this into the slope equation which is rise/run

2/1 = 2 = slope

Find the value of cos G rounded to the nearest hundredth.

Amiraneli [1.4K]

Answer:

$\sf \cos(G)=\dfrac{1}{2}$

Step-by-step explanation:

<u>Trigonometric ratios</u>

$\sf \sin(\theta)=\dfrac{O}{H}\quad\cos(\theta)=\dfrac{A}{H}\quad\tan(\theta)=\dfrac{O}{A}$

where:

$\theta$ is the angle
O is the side opposite the angle
A is the side adjacent the angle
H is the hypotenuse (the side opposite the right angle)

Given:

$\theta$ = G
A = GF = 2
H = EG = 4

$\implies \sf \cos(G)=\dfrac{2}{4}=\dfrac{1}{2}$
