Answer:
The investment after 5 years is $ 662.45.
Step-by-step explanation:
Principal, P = $ 600
Time, t = 5 years
Rate of interest, R = 2 %
Time , t = 5 years
The amount after the time 5 years is
[tex]A = P \times \left ( 1+\frac{R}{100} \right )^t\\\\A = 600\left ( 1+0.02 \right )^5\\\\A = 662.45[/tex]
So, the investment after 5 years is $ 662.45.

of them from European countries and the remaining 36 from America.
How many coins were from ASIAN countries?
A)18
B)30
C)108
D)216 step by step explanation please
Step-by-step explanation:
[tex] \frac{1}{2} = asian \\ \frac{1}{3} = european \\ 36 = american \\ \frac{1}{2} + \frac{1}{3} = \frac{3 + 2}{6} = \frac{5}{6} \\ \frac{6}{6} - \frac{5}{6} = \frac{1}{6} = 36 \\ \frac{1}{6} = 36 \: so \\ \frac{6}{6} =6 \times 36 = 216 \\ \frac{1}{2} \times 216 = asian \\ \frac{1}{2} \times 216 = 108asian \\ please \: mark \: brainliest[/tex]
There are total 108 coins belonging to Asian countries.
What is equation?An equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.
Given that, Balu had a collection of coins 1/2 of the coins were from Asian countries, 1/3 of them from European countries and the remaining 36 from America.
Let the total number of coins be x,
Establishing the equation, we get,
x/3+x/2+36 = x
Multiplying the equation by 6, we get,
2x+3x+216 = 6x
6x-5x = 216
x = 216
Therefore, the total numbers of coins are 216,
Since, there are 1/2 of total coins are Asian coins,
Therefore, number of Asian coins = 216 / 2 = 108
Hence, There are total 108 coins belonging to Asian countries.

The director of health services is concerned about a possible flu outbreak at her college.She surveyed 100 randomly selected residents from the college's dormitories to see whether they had received a preventive flu shot.The results are shown below.What is the probability that a dormitory resudent chosen at random from this group had a flu shot, given that he is male?
A: 39/80
B: 13/17
C: 39/100
D: 51/100
=============================================================
Explanation:
The "given that he is male" stated at the end means we only focus on the male column. This is because we know 100% that the person selected is male. Either we're told this by someone else, or we can determine this another way.
There are 39 males that got the flu shot out of 51 males total. The probability we're after is 39/51 = (3*13)/(3*17) = 13/17
It's effectively saying: out of every 17 males, 13 of them got the flu shot.

Step-by-step explanation:
Which equation shows the point-slope form of the line that passes through (3, 2) and has a slope of 1/3
O y + 2 =1/3(x + 3)
O y-2=1/3(x-3)
O y + 3 = 1/3(x+ 2)
O y-3= 1/3(x-2)
Answer:
y - 2 = 1/3(x - 3)
Step-by-step explanation:
Point slope form is y - y1 = m(x - x1), where m is the slope and (x1, y1) is a point on the line.
Plug in the slope:
y - y1 = m(x - x1)
y - y1 = 1/3(x - x1)
Plug in the given point:
y - y1 = 1/3(x - x1)
y - 2 = 1/3(x - 3)
So, the correct answer is y - 2 = 1/3(x - 3)
ABCD is a quadrilateral such that the measures of three of its interior angles are given as B=122 degrees, C= 75 degrees, D= 51 degrees, find m=A
please help me with explanation
Answer:
angle A is 112 degree.
Step-by-step explanation:
quadilateral have 4 angles .
sum of the interior angles of a quadilateral is 360 degree
Here,
angle A = be x
angle B = 122
angle C = 75
angle D = 51
Now,
angle A + angle B + angle C + angle D =360 degree
x + 122 + 75 + 51 = 360
x + 248 = 360
x = 360 - 248
x = 112

Answer:
Step-by-step explanation:
1 to find AB
in triangle ADB
here 4 and 2[tex]\sqrt{6}[/tex] are the legs of the right triangle so let them be a and b respectively.
AB is the hypotenuse (longest side ) and let it be x
using pythagoras theorem
a^2 + b^2 = c^2
4^2 + [tex](2\sqrt{6} )^2[/tex] = AB^2
16 + 4*6 = AB^2
16 + 24 = AB^2
40 = AB^2
[tex]\sqrt{40}[/tex] = AB
[tex]2\sqrt{10}[/tex] = AB
therefore AB =v[tex]2\sqrt{10}[/tex] .Hence proved .
In triangle ADC
here 6 and [tex]2\sqrt{6}[/tex] are the legs of the right angle so let them be a and b respectively. AC is the hypotenuse (longest side) so let it be c
usinfg pythagoras theorem
a^2 + b^2 = c^2
6^2 + [tex](2\sqrt{6} )^2[/tex] = AC^2
36 + 4*6 = AC^2
36 + 24 = AC^2
60 = AC^2
[tex]\sqrt{60}[/tex] = AC
[tex]2\sqrt{15}[/tex] = AC
To prove triangle ABC is a right angled triangle
AD and BD are the legs and AB is hypotenuse
according to pythagoras theorem to be the right angle triangle the sum of square of two smaller sides of a triangle must equal to the square of hypotenuse(longest side)
let two smaller sides be a and b respectively and c be hypotenuse
using pythagoras theorem
a^2 + b^2 = c^2
4^2 + [tex](2\sqrt{6} )^2[/tex] = [tex](2\sqrt{10} )^2[/tex]
16 +2^2*6 = 2^2*10
16 + 4*6 = 4*10
16 + 24 = 40
40 = 40
since both sides are equal it is proved that the triangle ABC is a right angled triangle.
Hope this helps u !!
Answer:

firstly you must find the hipotenus using the hipotenus formula AB is the hipotenus
(4)*2 + (2 square root 10)*2 = 40 juat press a calculator if you dont know
and then you press square root of 40 then you will get 2 square root 10 so you already prove that AB is 2 square root 10
When draining her hot tub, the height of the water in Brittany’s hot tub decreases at a rate of 2 inches per minute. After 9 minutes there are 11 inches of water in the tub. Assume that the height is decreasing at a constant rate.
a. Write an equation for the height of water left in the tub (h) as a function of the number of the minutes (t) that have elapsed.
b. What values of the domain, t, make sense? Why?
c. What values of the range, h, make sense? Why?
Step-by-step explanation:
a.
Let's give the starting amount of water as s. Every minute, 2 inches of water are lost, meaning that given the starting amount, s, we subtract 2 inches from s every minute, so s - 2 every minute = height of water left, so s - 2t (t representing minutes) = h
To figure out s, we simply plug our known value -- 9 minutes in and 11 inches left. s - 2(9) = 11, s-18=11, s= 29
29 - 2t = h
b. We know that we cannot have negative minutes, so the minimum amount of time that makes sense is 0. To figure out the maximum, we stop counting how much time has occurred when there is no water left, so we have to figure out when h = 0
29-2t = h = 0
t=14.5
Therefore, anything between 0 and 14.5 minutes makes sense
c. Anything between 0 and 29 makes sense because the height of water cannot be negative and we cannot get higher than the starting amount

Step-by-step explanation:
A data set lists weights (lb) of plastic discarded by households. The highest weight is 5.31 lb, the mean of all of the weights is x=2.088 lb, and the standard deviation of the weights is s=1.968 lb. a. What is the difference between the weight of 5.31 lb and the mean of the weights? b. How many standard deviations is that [the difference found in part (a)]? c. Convert the weight of 5.31 lb to a z score. d. If we consider weights that convert to z scores between −2 and 2 to be neither significantly low nor significantly high, is the weight of 5.31 lb significant?
Answer:
a) The difference is of 3.222 lbs.
b) 1.64 standard deviations.
c) Z = 1.64
d) Not significant, as the z-score of 1.64 is between -2 and 2.
Step-by-step explanation:
Normal Probability Distribution:
Problems of normal distributions can be solved using the z-score formula.
In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the p-value, we get the probability that the value of the measure is greater than X.
The mean of all of the weights is x=2.088 lb, and the standard deviation of the weights is s=1.968 lb.
This means that [tex]\mu = 2.088, \sigma = 1.968[/tex]
a. What is the difference between the weight of 5.31 lb and the mean of the weights?
This is [tex]X - \mu = 5.31 - 2.088 = 3.222[/tex]
The difference is of 3.222 lbs.
b. How many standard deviations is that [the difference found in part (a)]?
This is the z-score. So
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]Z = \frac{5.31 - 2.088}{1.968}[/tex]
[tex]Z = 1.64[/tex]
1.64 standard deviations.
c. Convert the weight of 5.31 lb to a z score.
Z = 1.64, as found above.
d. If we consider weights that convert to z scores between −2 and 2 to be neither significantly low nor significantly high, is the weight of 5.31 lb significant?
Not significant, as the z-score of 1.64 is between -2 and 2.
