If the probability of writing the correct answer to the question on an exam is 2/5, what are the odds against writing the correct answer?
Explanation
The probability of getting the correct answer is 2/5. This means there are 2 events of getting it right out of 5 events total. Since there are 2 events of getting it right, there are 5-2 = 3 events of getting it wrong.
The odds against getting the right answer is 3:2. We list the number of ways to get it wrong first, a colon, then the number of ways of getting it right.

The probability that Amy will reach in the jewelry box and pull out a necklace that is not silver is 3/20 and this can be determined by using the given data.
Given :
Amy has 20 necklaces in a jewelry box. The probability of reaching into the jewelry box and pulling out a silver necklace is 0.85.The following steps can be used in order to determine the probability that Amy will reach in the jewelry box and pull out a necklace that is not silver:
Step 1 - According to the given data, the probability of reaching into the jewelry box and pulling out a silver necklace is 0.85.
Step 2 - The overall probability is 1.
Step 3 - So, the probability that Amy will reach in the jewelry box and pull out a necklace that is not silver is calculated as:
P = 1 - 0.85
P = 0.15
P = 3/20
Therefore, the correct option is C).

Given f(x) = 3/2x - 8, solve for x when f(x)= 7
Answer:
x is 10 when f(x) = 7
Step-by-step explanation:
f(x) is another way of saying y=. The question is basically asking, what is the value of x when the 3/2x - 8 = 7
So, to do this, you are going replace y with it's numerical value. The numerical value given to you is 7. Now, you are going to solve for x (by isolating x).
[tex]7= \frac{3}{2} x-8\\7+8= \frac{3}{2} x-8+8\\15 = \frac{3}{2} x\\15 / \frac{3}{2} = (\frac{3}{2}x) / 3/2\\10=x[/tex]
f(10) = 7
Check your work?
Plug in 10 where you see x.
y = 3/2x - 8
y = (3/2)(10)-8
y = 7 ✅

5x - y= -7
3x - y= -2
-2.5, -5.5
-2.5, 11
5, 2.5
2.5, 5.5
Answer: -2.5, -5.5
Step-by-step explanation:
5x - y= -7
3x - y= -2 multiply by -1
5x - y= -7
-3x + y= +2 we add both equations
2x=-7+2, 2x=-5, x=5/2= -2.5
5(-2.5)-y=-7
- 12.5-y= -7 we simplify and get
-y=-7+12.5, -y=5.5, y=-5.5
Hi, could i please get some help with this I forgot the formula for it..... THANKS!!
Answer:
b = 12
Step-by-step explanation:
a² + b² = c²
a and b are the length of the sides in the right triangle and c is the hypotenuse.
since we know one leg and the hypotenuse, we can find the other leg.
9² + b² = 15²
81 + b² = 225
b² = 225 - 81
b² = 144
b = 12
Answer:
The answer is 12
Step-by-step explanation:
the formula is A^2+B^2=c^2
9² + b² = 15²
81 + b² = 225
b² = 225 - 81
b² = 144
b = 12

Answer:
The light blue/greenish one that says T=PV/K or Greeland
Step-by-step explanation:
We can make the equation more simplier by multiplying both sides by P to remove fractions.
It would become VP=KT
The only answer with VP or PV is B, or the T=PV/K
also, to isolate T, divide the VP=KT by K on both sides to isolate T.
VP/K=T

there are 84 calories in 100g of banana there are 87 calories in 100g of yoghurt priti has 60 g of banana and 150g of yoghurt for breakfast work out the total number of calories in this breakfast
Total calories intake of Priti is 180.9 calories
Given that;
Number of calories in 100g banana = 84 calories
Number of calories in 100g yoghurt = 87 calories
Amount of banana and yoghurt Priti have = 60g and 150g respective
Find:
Total calories intake of Priti
Computation:
Total calories intake of Priti = 60[84/100] + 150[87/100]
Total calories intake of Priti = 50.4 + 130.5
Total calories intake of Priti = 180.9 calories

x is ____
GR is ____
GB is ____
please help!
Answer:
x is 4
GR is 10
GB is 49
Step-by-step explanation:
If U is between G and B, then GU + UB = GB .... 1
If R is between G and U, GR + RU = GU ....2
Given
GR is 3x-2
RU is 5x+7
UB is 12
GB is 15x-11
Substitute2 into 1;
Frim 1;
GU + UB = GB
(GR+RU) + UB = GB
3x-2+5x+7+12 = 15x-11
8x+17 = 15x-11
8x-15x = -11-17
-7x = -28
x = 28/7
x = 4
Get GR:
GR = 3x-2
GR = 3(4)-2
GR = 12-2
GR = 10
Get GB:
GB = 15x-11
GB = 15(4)-11
GB = 60-11
