Consider the form x^2+bx+c. Find a pair of integers whose product is c and whose sum is b. In this case, whose product is 36 and whose sum is 20.
2, 18
Write the factored form using these integers.
(x+2)(x+18)
If a quadrilateral has one pair of sides
Answer:
0.4 or 
Step-by-step explanation:
James spun the arrow 30 times which means 30 is the total. In other words, it's your denominator (
). It landed on the blue section 12 times which means 12 is the part of the whole. In other words, it's your numerator (
). Plug in the entire fraction and you get 
. Divide 12 by 30 and you get 0.4 or if you divide both the numerator & denominator by 6, you get . Either one works, depending on what your question asks for.
Given:
The function is 
.
To find:
The function 
.
Solution:
We have,
Substitute f(x)=y.
Interchange x and y.
Divide both sides by 3.
Taking power 4 on both sides.
Subtract 7 from both sides.
Substitute 
.
Therefore, the correct option is C.
Answer:
Probability of the next spin landing on colour purple = (1/5) = 0.20
Step-by-step explanation:
Complete Question
A spinner is divided into four colored sections that are not of equal size: red blue purple and orange. The results of a number of spins is given as
Orange: 9
Red: 15
Blue: 24
Purple: 12.
The arrow on the spinner will be spun one more time. Based on these results, what is the probability that the arrow will land on the purple section?
The probability of an event based on trials is given as the number of successes for that event, n(E), divided by the total number of trials, n(S)
P(R) = n(E) ÷ n(S)
Number of successes for the spinner landing on purple = 12
total Number of trials = 9 + 15 + 24 + 12 = 60
Probability of the next spin landing on colour purple = (12/60) = (1/5) = 0.20
Hope this Helps!!!
