Answer:

log₅(3125) = 5

Step-by-step explanation:

Given:

log₅(3125)

Now,

using the property of log function that

logₐ(b) = \frac{\log(b)}{\log(a)}

thus,

Therefore, applying the above property, we get

⇒ \frac{\log(3125)}{\log(5)}   (here log = log base 10)

now,

3125 = 5⁵

thus,

⇒  \frac{\log(5^5)}{\log(5)}

Now,

we know from the properties of log function that

log(aᵇ) = b × log(a)

therefore applying the above property we get

⇒ \frac{5\log(5)}{\log(5)}

or

⇒ 5

Hence,

log₅(3125) = 5

For each day that Sasha travels to work, the probability that she will experience a delay due to traffic is 0.2. Each day can be
lions [1.4K]

Answer:

0.8213

Step-by-step explanation:

-This is a binomial probability problem given by the function:

P(X=x)={n\choose x}p^x(1-p)^{n-x}

Given that n=21 and p=0.2, the probability that she experience a delay on at least 3 days is calculated as:

P(X=x)={n\choose x}p^x(1-p)^{n-x}\\\\P(X\geq 3)=1-P(X

Hence, the probability that she experience delay on at least 3 days is 0.8213

Mrs Johnson has $110 to spend on parking will cost $12 and admission tickets will cost $140 per person including tax
Vaselesa [24]

<em>The answer is Ms Hernandez can bring up to 6 people to the zoo.</em>

<em />

<em>x -  the number of people that she can bring to the zoo</em>

<em>The parking will cost $7: a = 7</em>

<em>Admission tickets will cost $15.50 per person: b = 15.50x</em>

<em>She can spend on parking and admission tickets $100:</em>

a + b ≤ 100

a = 7

b = 15.50x

7 + 15.50x ≤ 100

15.50x ≤ 100 - 7

15.50x ≤ 93

x ≤ 93 / 15.50

x ≤ 6

Rewrite this number sentence 50 1/2 divided by 1/4 using multiplication
Shalnov [3]
This division question is asking how many 1/4 you can fit into 50 1/2.

We can fit 4 of them into 1 whole (4 x 1/4 = 1)
We can fit 8 of them into 2 wholes (8 x 1/4 = 2)

and so on.

But we have 50 1/2 wholes, so we would need 50 1/2 x 4.

The new number sentence is 50 1/2 x 4.
