Shawn has a bank account with $3,069. He decides to invest the money at 3.25% interest, compounded annually. How much will the investment be worth after 5 years? Round to the nearest dollar.
The investment worth after 5 years to the nearest dollar will be $3601.
What is compound interest?We know that the compound interest is given as
A = P(1 + r)ⁿ
Where A is the amount, P is the initial amount, r is the rate of interest, and n is the number of years.
Shawn has a bank account with $3,069. He decides to invest the money at 3.25% interest, compounded annually.
The worth of investment after 5 years is calculated as,
A = $3,069 x (1 + 0.0325)⁵
A = $3,069 x 1.0325⁵
A = $3,069 x 1.1734
A = $3601
The investment worth after 5 years to the nearest dollar will be $3601.

Carlos and his family left for the amusement park at 8:35 Ask Your Teacher The trip took 1 hour 55 minutes. What time did they arrive?
Answer:Carlos and his family arrived at 10:30
Step-by-step explanation:
The time Carlos and his family left for the amusement park =8:35
Since The trip took 1 hour 55 minutes., we have to add it to the time they left for the amusement park to now the time they arrived
8: 35 =8 hrs 35minutes
1 hr 55 minutes
90 minutes
but 90minues is greater than 60 so we convert to hours and minutres by dividing by 60 giving us
90/60=1.5hrs=1hr 30mins
8¹ hrs 35minutes
1 hr 55 minutes
10hrs 30 minutes
Therefore, They arrived at 10:30

Elena donates some money to charity whenever she earns money as a babysitter. What percent of her income does She donate?
Answer:
10%
Step-by-step explanation:
The question is incomplete due to missing data
Say she earns $1000
And she donates $100
Hence the percentage of her earnings she donates is
=100/1000*100
=10000/1000
=10%
Hence the percentage is 10%
The spinner above is used in a game. What is the theoretical probability of the given event with one spin? P (5)
Answer:
1 /8
Step-by-step explanation:
Given that :
Number of sections on spinner = (1,2,3,4,5,6,7,8) = 8
Number of 5's = 1
Recall :
Probability of event A = number required outcome / Total possible outcomes
P(5) = 1/8
Seventy percent of kids who visit a doctor have a fever, and 30% of kids with a fever have sore throats. What’s the probability that a kid who goes to the doctor has a fever and a sore throat?
Answer:
0.21
Step-by-step explanation:
Probability calculates the likelihood of an event occurring. The likelihood of the event occurring lies between 0 and 1. It is zero if the event does not occur and 1 if the event occurs.
For example, the probability that it would rain on Friday is between o and 1. If it rains, a value of one is attached to the event. If it doesn't a value of zero is attached to the event.
Probability that a kid who goes to the doctor has a fever and a sore throat = probability a child would have fever x probability a child would have a sore throat

A sample of 23 women athletes, aged 20 was taken. The systolic blood pressure of these women had an average of 112 with a standard deviation of 3.3. Calculate a 90% confidence interval for the average systolic blood pressure of 20-year old women athletes.
Answer:
Step-by-step explanation:
average of 112 with a standard deviation of 3.3. Calculate a 90% confidence interval for the average systolic blood pressure of 20-year old women athletes.
From the above question
Number of samples = 23 , less than 30,
Hence, we find confidence interval using t score
Confidence Interval using t score =
Mean + t score × standard deviation/√n
Step 1
We find the degree of freedom
= N - 1
= 23 - 1
= 22

Consider the plane T. and three collinear (but not coplanar) points P, Q, and W.
Can either P, Q, or Wbe a point on the plane T?
A Yes, because if points are collinear, they must all fall on the same plane and be coplanar.
B Yes, because even if points are collinear, one of the points may fall on a plane while the others do not.
C No, because if points are collinear, they must all fall on the same plane and be coplanar.
D No, because even if points are collinear, one of the points may fall on a plane while the others do not.
Answer:
B Yes, because even if points are collinear, one of the points may fall on a plane while the others do not.

5. Given AADL AAKM with AD = 14, DK = 21, and
AL= 15. What is the measure of LM?
Answer:
22.5
Step-by-step explanation:
first of all, the first sign in the designations of the triangles is not an A. it is the Greek Delta (capital) sign. standing for "triangle" due to its shape.
as the diagram shows (and the description says correctly), ADL and AKM are similar triangles.
that means they have the same angles.
and in order to keep the same angles even when the lengths of the sides are different, the relative relation of the side lengths must be the same for all sides.
that means, if one side changes by a factor f, then both other sides must change by the same factor.
so, by checking the change factor for AD (to AK), we can then determine the change of AL to AM. and then we simply subtract AL from AM and get LM.
the original AD = 14.
AK = AD + DK = 14 + 21 = 35
the change factor f is then AK/AD = 35/14 = 5/2
in other words AD grew by a factor of 5/2.
AM is then created by applying the same factor to AL.
=> AM = 15 * 5 / 2 = 75 / 2 = 37.5
=> LM = AM - AL = 37.5 - 15 = 22.5
