The answer is 10 all u do is solve the equation 8-4 and the multiply by 2 then 10 and then divide that by 8 which gives u 10
Answer:
A number line with a closed circle on -8, an open circle on 9, and shading in between
Answer:
![29+\sqrt{5}](https://tex.z-dn.net/?f=29%2B%5Csqrt%7B5%7D)
Step-by-step explanation:
Let
for simplicity. now our equation is
(2a+1)(3a-1)
now expand
2a*3a-2a+3a-1 = 6a^2+a-1
remember that ![\sqrt{5} = a](https://tex.z-dn.net/?f=%5Csqrt%7B5%7D%20%3D%20a)
thus we get![6\sqrt{5}^2+\sqrt{5}-1 = 6(5)-1+\sqrt{5}=30-1+\sqrt{5}=29+\sqrt{5}](https://tex.z-dn.net/?f=6%5Csqrt%7B5%7D%5E2%2B%5Csqrt%7B5%7D-1%20%3D%206%285%29-1%2B%5Csqrt%7B5%7D%3D30-1%2B%5Csqrt%7B5%7D%3D29%2B%5Csqrt%7B5%7D)
Answer: 175.
Step-by-step explanation:
Since, Let there could be total number of vehicle parked = x
And, According to the question, 2/5 of the parking spaces are for cars.
Therefore, Number of cars are 2x/5
But, there were 200 car parked.
So 2x/5 = 200 ⇒x=500
That is, 500 vehicle can be parked in the parking lot.
And, Again from the question, The parking lot was 3/4 full.
The total vehicle that parked = 3/4 of 500 = 375
Therefore total number of buses= The total vehicle that parked - the total number of car that parked = 375-200=175.
Answer:
<u>P(three tails) = 27/125 or 21.6%</u>
<u>P(two tails followed by one head) = 18/125 or 14.4%.</u>
Step-by-step explanation:
1. Let's review the information provided to us to answer the questions correctly:
Probability of getting a head when a biased coin is tossed = 2/5
therefore,
Probability of getting a tails when a biased coin is tossed = 3/5
2. Find the following probabilities and select the correct solution.
P(three tails) =
3/5 * 3/5 * 3/5 = 27/125 or 21.6%
P(two tails followed by one head) =
3/5 * 3/5 * 2/5 = 18/125 or 14.4%.
