re are 8 times as many males as females on the maths course at university. What fraction of the course are female?
Give your answer in its simplest form.
Answer:
8/9
Step-by-step explanation:
Let
x = number of miles on the math course
There are 8 times as many males as females
Number of females = 8x
Total students of the course = number of males + number of females
= x + 8x
= 9x
Total students of the course = 9x
What fraction of the course are female?
Fraction of the course that are females = number of females / Total students of the course
= 8x / 9x
= 8/9
Fraction of the course that are females = 8/9

A piece of string 85 cm is divided into three pieces in the ratio 2 : 3: 5. Calculate: i) shortest piece
Answer: 17 cm
Step-by-step explanation:
First step is to add up the numbers in the ratio:
= 2 + 3 + 5
= 10
The shortest piece according to the ratio is the 2 in the ratio. To find out the length this 2 corresponds with, use two as the numerator and 10 as the denominator:
= 2 / 10 * 85 cm
= 17 cm

A six sided dice is rolled twice.
What is the probability that the first roll is an even number and the second roll is a number greater than 4?
Answer: 1/6 chance
Step-by-step explanation:
FIRST ROLL:
even numbers are 2, 4, and 6
3/6 or 1/2 chance of rolling even (50%)
SECOND ROLL:
numbers greater than 4 are 5 and 6
2/6 or 1/3 chance of rolling a number greater than 4 (33 1/3%)
MATH:
1/3*1/2 = 1/6 or about 16-17%

Chords AB and CD intersect as sho below. Find the length of CD. Please answer with work, and please, no links.
Answer:
39
Step-by-step explanation:
The chords are equal to eachother. First multiply their divided lengths together:
9(3x-9)=21(x+1)
27x-81=21x+21
x=17
CD= 21+x+1
21+17+1=39
CD= 39
Chords AB and CD intersect as shown in the given figure. The chords are equal to each other. The length of CD is 17.
What is the relation between the line perpendicular to the chord from the center of the circle?If the considered circle has center O and chord AB, then if there is perpendicular from O to AB at point C, then that point C is bisecting(dividing into two equal parts) the line segment AB.
Or
|AC| = |CB|
Chords AB and CD intersect as shown below.
The chords are equal to each other.
Therefore,
[tex]9(3x-9)=21(x+1)\\27x - 81 = 21x + 21\\\\27x - 21x= 81 + 21\\\\x= 17[/tex]
CD = 21 + x + 1
21 + 17 + 1 = 39
CD = 39

Answer:
? = √87 ≈ 9.33
Step-by-step explanation:
The square of the hypotenuse (h) of the small triangle is the sum of the squares of its legs.
h^2 = 5^2 + 12^2 = 25 +144 = 169
The square of the hypotenuse of the large triangle is also the sum of the squares of its legs.
h^2 +?^2 = 16^2
169 +?^2 = 256
?^2 = 256 -169 = 87
Taking the square root, we find the missing leg length to be ...
? = √87 ≈ 9.33

Question 2 of 40
Elena is going to a farmer's market for fresh produce. She has two markets to
choose from and hopes to buy both cherries and asparagus. The table shows
the probability that each type of produce will be available at the markets.
North
market
South
market
Cherries
0.8
0.65
Asparagus
0.55
0.6
Assuming that the availability of cherries and the availability of asparagus are
independent of each other, which market should Elena choose to maximize
her chance of buying both?
To maximize the chances of buying cherries as well as asparagus, Elena should choose the North market. There is 0.44 probability of both cherries and asparagus.
What is probability?"Probability is a branch of mathematics which deals with finding out the likelihood of the occurrence of an event."
Formula of the probability of an event A is:P(A) = n(A)/n(S)
where, n(A) is the number of favorable outcomes,
n(S) is the total number of events in the sample space.
What are independent events?"These are two events wherein the occurrence of one event does not affect the occurrence of another event"
Probability of independent events:If A, B are independent events then their combine probability is given by,
P(A ∩ B) = P(A) × P(B)
For given example,
Let P(A) represents the probability of cherries available at market and P(B) represents the probability of asparagus available at market.
The availability of cherries and the availability of asparagus are
independent of each other
So, the probability of buying cherries as well as asparagus from the North market would be,
⇒ P = P(A) × P(B)
⇒ P = 0.8 × 0.55
⇒ P = 0.44 ....................(1)
And the probability of buying cherries as well as asparagus from the South market would be,
⇒ P = P(A) × P(B)
⇒ P = 0.65 × 0.6
⇒ P = 0.39 .......................(2)
From (1) and (2),
To maximize the chances of buying cherries as well as asparagus, Elena should choose the North market. There is 0.44 probability of both cherries and asparagus.
