four added to twice a number yield 26/5. Find the number.
Answer:
3/5 is the answer
sry if it's wrong
Answer:
X=3/5
Step-by-step explanation:
Let number=X
Solution
2x+4=26/5
Cross multiply then we get
10x+20=26
10x=26-20
10x=6
X=6/10
X=3/5
So the no is 3/5
With 95% confidence, the researcher estimates the mean birth weight of all babies born to women who are over the age of 40 to be between 2935 and 3135 grams. The researcher wants to maintain the 95% level of confidence but report a confidence interval with a smaller margin of error. What should she do
This question is incomplete, the complete question is;
A medical researcher wants to estimate μ, the mean weight of babies born to women over the age of 40.
The researcher chooses a random sample of 100 pregnant women who are over 40. Using the mean birth weight of the 100 babies in the sample, the researcher calculates the 95% confidence interval for μ.
With 95% confidence, the researcher estimates the mean birth weight of all babies born to women who are over the age of 40 to be between 2935 and 3135 grams.
The researcher wants to maintain the 95% level of confidence but report a confidence interval with a smaller margin of error. What should she do
a) Redo the study and choose a different sample of size 100
b) Redo the study, but this time with a sample size 64
c) Redo the study, but this time with a sample 225
Answer:
Option C) is the correct answer.
C) Redo the study, but this time with a sample 225
Step-by-step explanation:
Given that;
A medical researcher wants to estimate μ, the mean weight of babies born to women over the age of 40.
n = 100
95% confidence interval is given ( 2935, 3135)
But the researcher wants to maintain the 95% level of confidence as well as smaller margin of error.
Therefore we have to reduce the margin of Error
and we know that if the sample size increases, the margin of Error decreases i.e it becomes smaller.
so the best option for the researcher is to redo the study with a larger sample size so the margin of Error becomes smaller.
Option C) is the correct answer.
c) Redo the study, but this time with a sample 225
A box contains 14 large marbles and 11 small marbles. Each marble is either green or white. 8 of the large marbles are green, and 5 of the small marbles are white. If a marble is randomly selected from the box, what is the probability that it is small or green?
Answer: 19/25.
Step-by-step explanation:
Given data:
Large marbles = 14
Small marbles = 11.
8 large marbles = green.
5 of small marbles = white.
Solution:
If 8 of large marbles are green, therefore the remaining 6 are white.
Likewise for the small marbles the remaining 6 are green marbles.
Total number of marbles = 14 + 11
= 25.
P(small or green) = P(small) + P (green) – P (Both)
= 11/25 + 14/25 – 6/11
= 19/25
Answer:
Answer is 0.7536
Step-by-step explanation:
Large Marbles = 14 Small Marbles = 11
Green LM = 8 Green SM = 6
White LM = 6 White SM = 5
QUESTION:
If a marble is randomly selected from the box, what is the probability that it is small or it is green?
Note the use of "or" and not "and".
SOLUTION:
In this case, the two events - small marble & green marble - are NOT mutually exclusive. This means that sometimes they occur together. We can have a marble that is both small and green!
The formula for this probability is hence
P(A or B) = P(A) + P(B) - P(A and B)
Let A = The event that the selected marble is small
B = The event that the selected marble is green
Total number of marbles = 14 + 11 = 25
P(A or B) = 11/25 + (8+6)/25 - [P(A) × P(B)]
P(A or B) = 11/25 + 14/25 - [11/25 × 14/25]
= 0.44 + 0.56 - 0.2464 = 1 - 0.2464 = 0.7536

A salesperson makes 8% commission on everything she sells. How much money would she make if she sold $200 worth of merchandise?
Answer:
$16
Step-by-step explanation:
A sales person makes 8% on everything she sells
She sold $200 worth of merchandise
The amount of money that will be made can be calculated as follows
= 8/100 × 200
= 0.08 × 200
= $16
Hence the sales person will make $16
Question 1 1 The area of a rectangle is 1 2/3 square feet. The width of the rectangle is 5/6 feet. What is the length of the rectangle? o foot D 11. feet 0 2 feet O2 feet Question 2 1 p
Answer:
2ft
Step-by-step explanation:
Given parameters:
Area of the rectangle = [tex]1\frac{2}{3}[/tex]ft²
Width of the rectangle = [tex]\frac{5}{6}[/tex]ft
Unknown:
Length of the rectangle = ?
Solution:
The area of a rectangle is given as:
Area of rectangle = length x breadth
Now insert the parameters and solve for length
[tex]\frac{5}{3}[/tex] = L x [tex]\frac{5}{6}[/tex]
L = [tex]\frac{5}{3}[/tex] x [tex]\frac{6}{5}[/tex] = 2ft

You are shopping for a new computer monitor. It is regularly priced at $200 but it is now on sale for 25% off. After the sale discount is applied, you can also use your 20% off coupon. What is the final price?
a. 110
b. 120
c. 130
d. 140
Answer:
b=120
Step-by-step explanation:
Using proportions, it is found that the final price of the new computer monitor is given by:
b. 120
What is a proportion?A proportion is a fraction of a total amount, and the measures are related using a rule of three.
It is regularly priced at $200 but it is now on sale for 25% off, hence 75% of $200 is paid, so:
P1 = 0.75 x 200 = 150.
You can also use your 20% off coupon, hence the final price is of 80% of $150, then:
FP = 0.8 x 150 = $120.
Which means that option B is correct.

Which equation is equivalent to n + 4 = 11? *
O (n +4 × 2 = 11
(n + 4) x 2 = 1112
(n+ 4) x 2 = 1184
O (n+4) x 2 = 11 * 2

Answer:
(n + 4) *2 = 11 * 2
Step-by-step explanation:
(n + 4) *2 = 11 * 2
Divide both sides by 2
[tex]\frac{(n + 4) *2}{2} = \frac{11 * 2}{2}[/tex]
n + 4 = 11

b. $120 $80
c. $80: $120
d. $300 : $200
Answer:
b) $120 , $ 80
Step-by-step explanation:
