Answer:
$195
Step-by-step explanation:
$300*.65 (your precent turns to a decimal) = $195 left
Given:
900 students
35% are on the honor roll
63% have part-time jobs
26% are on the honor roll and have part-time jobs
<span>What is the probability (rounded to the nearest whole percent) that a randomly selected student is on the honor roll, given that the student has a part-time job?
</span>
honor roll: 35%
part time job: 63%
35% x 63% = 22.05% or 22%
Answer:
L(t) = 1100(1.87)^(t/2.4)
Corrected question;
On the first day of spring, an entire field of flowering trees blossoms. The population of locusts consuming these flowers rapidly increases as the trees blossom. The locust population gains 0.87 of its size every 2.4 days, and can be modeled by a function, L, which depends on the amount of time, t (in days). Before the first day of spring, there were 1100 locusts in the population. Write a function that models the locust population t days since the first day of spring.
Step-by-step explanation:
Given;
Initial amount P = 1100
Rate of growth r = 87% = 0.87
Time step k = 2.4 days
The case above can be represented by an exponential function;
L(t) = P(1+r)^(t/k)
Where;
L(t) = locust population at time t days after the first day of spring
P = initial locust population
r = rate of increase
t = time in days
k = time step
Substituting the given values;
L(t) = 1100(1+0.87)^(t/2.4)
L(t) = 1100(1.87)^(t/2.4)
the locust population t days since the first day of spring can be modelled using the equation;
L(t) = 1100(1.87)^(t/2.4)
The answer for the question shown above is: <span>B. Both powers should be in the dominator with positive exponent.
The explanation is shown below:
1. You have the following expression given in the problem above:
x⁻3y⁻9
2. The negative exponents indicates that </span>x⁻3y⁻9 should be in the denominator with positive exponents. Therefore, you have:
x⁻3y⁻9=1/x^3y^9
