Answer:
There are 10 boys and 6 girls in the class
Step-by-step explanation:
The given parameters are;
The number of boys = The number of girls + 4
The number of students in the class = 16
Let x represent the number of girls in the class and let y represent the number of boys in the class
Therefore;
y = x + 4...(1)
x + y = 16...(2)
Making y the subject of equation (2) gives;
y = 16 - x
Equating the values of y from equation (1) and equation (2) gives;
x + 4 = 16 - x
Which gives;
2·x = 16 - 4 = 12
x = 12/2 = 6
x = 6
The number of girls = x = 6
From equation (1), we have;
y = x + 4 = 6 + 4 = 10
y = 10
The number of boys = y = 10.
Answer:
I believe RS is 38.
Step-by-step explanation:
RT is 50, which is the total length of the number line. ST is 12, which is one part of the line. To find RS. I believe you have to subtract 50-12 to get the length of the missing part. which is RS.
50-12 = 38
Answer:
The <u>sample proportion</u>, denoted by ^p, is given by the formula ^p=
, where x is the number of individuals with a specified characteristic in a sample of n individuals.
Step-by-step explanation:
Sample proportion is used to determine sample mean, sample standard error and test the hypotheses about the population.
<em>sample mean</em> can be stated as p and <em>sample standard error</em> can be found using the equation
where
- p is the sample proportion
And if n×p×(1-p)≥10, then sample is assumed large enough to assume normal distribution and apply statistical test.

Answer: 4 years after the original investment, it is approximately $1,093.
Step-by-step explanation:
Hi, to answer this question we have to apply the simple interest formula:
I = p x r x t
Where:
I = interest
P = Principal Amount
r = Interest Rate (decimal form)
t= years
Replacing with the values given
I = 1000x (2.25/100) x t
- It will triple in approximately 3 years. FALSE
I = 1000x (2.25/100) x 3 =67.5
1000+67.5 = 1067.5
- It will no longer grow after several years: False, it will grow because it has a growth rate.
- 4 years after the original investment, it is approximately $1,093. TRUE
I = 1000x (2.25/100) x 4 =90
1000+90 = $1090
- It will double in approximately 10 years.
I = 1000x (2.25/100) x 10 =225
1000+90 = $1225
