in how many years 1600 invested at 5% will amount to 1920
Answer:
principal=1600
rate=5%
amount=1920
time=x
interest=p*t*r/100
=1600*x*5/100
=8000x/100
80x
amount=principal +interest
1920=1600+80x
1920-1600=80x
320/80=x
4=x
therefore after 5 years 1600 amount to 1920 at the rate of 5%

A video store charges $5 per game rental plus $12 to rent the game system. Write an expression for renting the game system and a number of games.
Answer:
12 + 5X = Y
Step-by-step explanation:
Given that a video store charges $ 5 per game rental plus $ 12 to rent the game system, to write an expression for renting the game system and a number of games the following logical reasoning must be performed:
5 = variable not fixed, depends on the number of games
12 = fixed variable
X = number of games
Y = total value
12 + 5X = Y
Thus, if 5 video games were rented, the equation would operate as follows:
12 + 5x5 = Y
12 + 25 = Y
37 = Y

Answer: 52.
Step-by-step explanation: I don't know if you know about PEMDAS, but it basically stands for (Parenthesis, Exponents, Multiplication, Division, Addition, Subtraction). So first, we would do Parenthesis. In the parenthesis, we have 3 + 4 - 1. Addition and Subtraction are the same, since they are inverse operations. We would start from left to right, so the addition goes first. 3 + 4 = 7. Now we are left with 7 - 1. 7 - 1 = 6. The equation so far is: 16/4 + 54 - 6. Next, we will do division. 16 ÷ 4 = 4. The equation so far is: 4 + 54 - 6. Now, we have to add 4 + 54 since we are doing it from left and right. 54 + 4 = 58. We are left with 58 - 6. 58 - 6 = 52. So your final answer is 52. Hope this helps!! :) **I tried my best**
So I dont know what equation Im supposed to do. I'm confused either it is addition or multiplication.

A recent study revealed that the average weight of babies born in the United States is normally distributed with a mean of 7.5 pounds. This number is lower than recent years and so researchers are interested in determining what factors are associated with lower birth weights. One researcher decides to look at the age of the mother to determine if younger mothers have babies that are significantly heavier or lighter than average. To study this the researcher collects data from 87 babies who were born to mothers between the ages of 16 and 18. Only one baby was measured per mother. Twins and other multiple births were excluded. The average weight for these babies was 7.3 pounds with a standard deviation of .6 pounds.
Which of the following statements is relevant to the assumption of Normality?
a. the standard deviation for young mothers is not expected to be different than the standard deviation in the population
b. only one baby was measured per mother
c. weights of babies are normally distributed in the population
d. the study used a sample that is different than the comparison population and measured weight on a ratio scale
Answer:
a. the standard deviation for young mothers is not expected to be different than the standard deviation in the population
Step-by-step explanation:
The population mean = μ= 7.5
Sample mean = x`= 7.3
Sample standard deviation= s= 0.6
Sample size = 87
Assuming normality we perform z test
z= x`-u/s/√n
z= 7.3-7.5/0.6/√87
z= -3.11
The critical region for 0.05 for two tailed test is z>+1.96 and Z<-1.96
Since the calculated z= -3.11 falls in the critical region Z<-1.96 we conclude that birth rate is lower in the young mothers.
a. the standard deviation for young mothers is not expected to be different than the standard deviation in the population
Only choice a is correct because when n > 30 the population standard deviation and the sample standard deviation are assumed to be normal
Choice b cannot be the correct option because it is already inferred that only one baby was measured per mother.
Choice C cannot be also the best choice because it is already assumed.
Choice d is totally incorrect.

What is an Inscribed Angle ?An inscribed angle in a circle is formed by two chords that have a common end point on the circle. This common end point is the vertex of the angle.
An inscribed angle in a circle is formed by two chords that have a common end point on the circle. This common end point is the vertex of the angle.
In the circle, the two lines AC and AD intersect outside the circle at the point A .
m∠CAE=1/2(m CD−m BE)
The formula for the angle between 2 secants is
1/2 (124 - 16)
= 1/2 * 108
= 54°
Therefore the measure of CA = 54°

What is the median please help please help
Answer:
54.5
Step-by-step explanation:
To find the median, first we have to put the numbers in ascending/increasing order.
43, 60, 50, 36, 58, 50, 73, 59, 69, 51 is your set
36, 43, 50, 50, 51, 58, 59, 60, 69, 73 is your set in order.
The median is the middle number of the data set. Your set has an even number of entries, so we have to average the 2 middle numbers, which are 51 and 58.
36, 43, 50, 50, 51, 58, 59, 60, 69, 73
51 + 58 = 109
109/2 = 54.5

Answer:
∠ h = 75°
Step-by-step explanation:
∠ e = ∠ a = 105° ( corresponding angles )
∠ h and ∠ e are adjacent angles and sum to 180°
∠ h + 105° = 180° ( subtract 105° from both sides )
∠ h = 75°

What is coordinates of point C?
Answer:
(3,6)
Step-by-step explanation:
Using the midpoint segment formula
M(X, Y) = [(ax1+bx2/2, ay1+by2/2)]
Given (-2 -6) and (4,6) divided in the ratio 1:5
X = 1(-2) + 5(4)/1+5
X = -2+20/6
X = 18/6
X = 3
Similarly
Y = 1(-6)+ 5(6)/1+5
Y = -6+30/6
Y = 24/6
Y = 4
Hence the required coordinate of C is (3,6)
