Moriah studied for 3 hours to prepare for her history exam. How many minutes did she study?
Answer:
180
Step-by-step explanation:
Every hour is 60 minutes. To find the total number of minutes she studied, you would have to multiply 3 x 60.
3 x 60 = 180
Answer: 180 minutes.
Step-by-step explanation: 3 hours is equal to 60+60+60 because there is 60 minutes in 1 hour so 60+60 is 120+60=180 therefore, she studied for 180 minutes.
Omar wants to determine cos(- (2pi)/3) using the ratios of the 30 degrees - 60 degrees - 90 degrees right triangle . How shoulc he use this information to determine cos(- (2pi)/7)
Answer:
its D
Step-by-step explanation:
The right angle triangle with 30-60-90 degrees is the special triangle in which these angle will have the side ratio of 1, [tex]\sqrt{3} [/tex] and 2. The value of the [tex] \cos\dfrac{(-2\pi)}{3} [/tex] which Omar wants to determine is -1/2.
Given information-
Omar wants to determine the value of
[tex] \cos\dfrac{(-2\pi)}{3} [/tex]
As the degree is in the pi form. Use the conversion rate [tex]\dfrac{180}{\pi} [/tex] to convert the degree,
[tex]=\dfrac{(-2\pi)}{3} \times\dfrac{180}{\pi} [/tex]
[tex]=-120[/tex]
As the angle -120 degrees is in the third quadrant hence the reference angle is 60 degrees(by calculating as (180-theta).
30-60-90 triangleNow the right angle triangle with 30-60-90 degrees measure angle. Such angle will have the side ratio of 1, [tex]\sqrt{3} [/tex] and 2.
Here 2 is the hypotenuse of the right triangle. The side opposite to the angle measure [tex]\sqrt{3} [/tex] and the side adjacent to the angle measures 1 in ratio.
Now the cos theta is the ratio of the adjacent side and hypotenuse thus,
[tex] \cos\dfrac{(-2\pi)}{3} =-\dfrac{1}{2} [/tex]
Negative sign is used for the third quadrant where x axis is negative.
[tex] \cos\dfrac{(-2\pi)}{3} =-\dfrac{1}{2} [/tex]
Thus the value of the [tex] \cos\dfrac{(-2\pi)}{3} [/tex] which Omar wants to determine is -1/2.

Suppose that Stephen is the quality control supervisor for a food distribution company. A shipment containing many thousands of apples has just arrived. Unknown to Stephen, 13% of the apples are damaged due to bruising, worms, or other defects. If Stephen samples 10 apples from the shipment, use the binomial distribution to estimate the probability that his sample will contain at least one damaged apple. Select the true statement.
A. Stephen can use a sample of size 10 to reliably determine if the truck load contains damaged apples.
B. Stephen could use a sample of size less than 10 to reliably determine if the truck load contains damaged apples.
C. Stephen could have used a normal approximation to determine this probability.
D. A sample of size 10 is too small to reliably determine if the truck load contains damaged apples.
E. Stephen should sample with replacement so that the probability is exactly binomial.
Answer:
D. A sample of size 10 is too small to reliably determine if the truck load contains damaged apples.
Step-by-step explanation:
We have probability of having damaged apple = 13%
= 13/100
= 0.13
Sample size n = 10
Using the binomial distribution
P(X=x) = nCx * P^x(1-P)^n-x
Probability sample will have at least one damaged apple
= P(X>=1) = 1-p(x<1)
= 1 - P(X=0)
= 1-(10C0 *P⁰(1-0.13)¹⁰
= 1 - 1(1-0.13)¹⁰
= 1 - 0.87¹⁰
= 1 - 0.2484
= 0.7516
The answer is option D. A sample of size 10 is too small to reliably determine if the truck load contains damaged apples.

What is the CONSTANT in the expression 3k + 12?
Answer: 12
Step-by-step explanation:
The constant of the expression is 12.
What is a constant?'A constant is a value or number that never changes in expression that is it's constantly the same.'
According to the given problem,
In the expression 3k + 12 , k is a variable. A variable is a quantity that may change with respect to the mathematical criteria.
If k = 1, the value of the expression is (3 × 1) + 12 = 15
k =2, the value is (3 × 2) + 12 = 18
But we can see that no matter the value of k is, the expression has to be added with 12.
Hence, we can conclude that since the value of 12 does not change irrespective of the changing values k, the constant of this expression is 12.

If PQRS is a rhombus, find m
Answer:
m<PQR = 82°
Step-by-step explanation:
In a Rhombus, the diagonals bisect its angles. This means that they divide each the four angles into two equal parts.
Therefore:
(4x - 27)° = (2x + 7)°
Solve for x
4x - 27 = 2x + 7
Collect like terms
4x - 2x = 27 + 7
2x = 34
Divide both sides by 2
2x/2 = 34/2
x = 17
✔️m<PQR = (4x - 27) + (2x + 7)
Plug in the value of x
m<PQR = (4*17 - 27) + (2*17 + 7)
m<PQR = 41 + 41
m<PQR = 82°

True or False, Drawing a Jack from a deck of cards, not replacing it, and then drawing a king are examples of dependent events
Answer: The probability of drawing a king from the deck has been changed when a Jack is drawn and not replaced back. So the two events are dependent. The answer to this question is TRUE
Step-by-step explanation:
Two events are dependent if the occurrence of one event affects the probability of occurrence of the other event.
Total number of cards in a deck are 52. There are 4 jacks and 4 kings.
If we simply pick up a king from the deck, the probability of picking a king would be
However, when a Jack is drawn from the deck of cards and not replaced back, the number of total cards reduces by 1. So now the total number of cards in the deck is 51 with 4 kings. In this case the probability of drawing a king is 4/51

Answer:
See answers below
Step-by-step explanation:
Perimeter of a square = 4L
L sis the side length of the square
L = 5x^4y^2
perimeter = 4(5x^4y^2)
perimeter = 20x^4y^2
2) Length = 6x-10
Width = 4x+3
Area of rectangle = Length * Width
Area of rectangle = (6x-10)(4x+3)
Area of rectangle = 24x^2+18x-40x-30
Area of rectangle= 24x^2-22x-30
perimeter = 2(L+W)
perimeter 2(6x-10+4x+3)
perimeter = 2(10x-7)
perimeter = 20x-14
Hence the perimeter of the rectangle is 20x-14
