Answer:

A. 15 c squared Start Root 3 End Root

Step-by-step explanation:

$3\sqrt{5c} *\sqrt{15c^3} \\$

Multiply the terms inside the square roots together

$3\sqrt{75c^4}$

Look for items that are perfects squares

$3\sqrt{25*3*c^4}$

We can separate terms inside the square root into separate square roots

$3\sqrt{25} *\sqrt{3}*\sqrt{c^4}$

$3*5 *\sqrt{3} *c^2$

Combine like terms

$15c^2\sqrt{3}$

visited museum   didn't visit museum Total

visited zoo 9   14 23

didn't visit zoo   5 2 7

Total 14 16 30

Simply look at the table and check the number that corresponds to visitors who visited the museum but did not visit the zoo. The number is 5.
Divide it by the total number of people surveyed. Total is 30.

Probability visited the museum but did not visit the zoo = 5/30 = 0.16666 or 16.67%</span>

Answer:

0.150,0.595

Step-by-step explanation:

Given that at a self-service gas station, 40% of customers pump regular gas, 35% pump midgrade, and 25% pump premium gas. Of those who pump regular, 30% pay at least $30. Of those who pump midgrade, 50% pay at least $30. And of those who pump premium, 60% pay at least $30.

Regular gas Midgrade Premium gas Total

Percent 40 35 25 100

atleast 30 30% 50% 60%

a) The probability that the next customer pumps premium gas and pays at least $30

= $0.25*0.60\\=0.150$

b) the probability that the next customer pays at least $30

= P(regular and pays atleast 30%)+P(premium and pays atleast 30%)+P(midgrade and pays atleast 30%)

= $0.40*0.30+0.35*0.50+0.25*0.60\\=0.12+0.175+0.30\\=0.595$

When an exponential function is given as
f(x)=ab^x, and
knowing that b^0=1, that means that
f(0)=ab^0=a value of function when x=0, or the initial value.
In the case of
f(x)=20.b^x, f(0)=20.b^0 = 20 (initial value)

If b=1.2, then the hourly growth rate is (1.2-1)=0.2=20%.
If b=1.85, then the hourly growth rate is (1.85-1)=0.85=85%.
