the same number, there is no room for modification, or increasing the

What is the solution to the system of equations below 2X minus Y equals 10 and Y equals -1/2 X plus 5
Answers
Answer:
x = 2 , y = 4.
(2,4)
Step-by-step explanation:
Simultaneous equation:
2x - y = 10 E1
y = [tex]-\frac{1}{2}x[/tex] + 5 E2
Substitute equation 2 into equation 1 for the y value.
2x - [tex]-\frac{1}{2}x[/tex] + 5 = 10
2x - [tex]-\frac{1}{2}x[/tex] = 5
2x + [tex]\frac{1}{2}x[/tex] = 5
[tex]\frac{5}{2} x[/tex] = 5
x = 2
Substitute the x value into equation 2.
y = [tex]-\frac{1}{2}2[/tex] + 5
y = -1 + 5
y = 4

You are interested in getting an investment portfolio started with any extra money you make from your part time job while also going to school. While flipping through the latest edition of Money magazine, you read an article that of a survey of magazine subscribers, 164 were randomly selected and analyzed. A 95% confidence interval was constructed for the proportion of all subscribers who made money in the previous year in their investments, which was ( 0.6904 , 0.8218 ). What is the correct interpretation of this confidence interval
Answers
Answer:
We are 95% confident that the proportion of all Money magazine subscribers that made money in the previous year from their investments is between 0.6904 and 0.8218
Step-by-step explanation:
The confidence interval gives a range of values for which a population proportion will fall based on a given level of confidence, in this case it is 95%. This interval is calculated using the sample proportion. The sample proportion in this case is based on a number of samples examined. The interval we obtain in this case (0.6904; 0.8218) is the estimated range which we expect the population proportion to fall ; with a 95% confidence.

Answer:
<ADB = 75 degrees
Step-by-step explanation:
We know, a straight line has an angle of 180 degrees.
A = (180-143) = 37 degrees.
A + C = (37 + 38) = 75 degrees.
The angles of a triangle will always add up to 180 degrees.
<ADC = (180-75) = 105 degrees.
So,
<ADB = (180-105) = 75 degrees.

y = x + 2
3x + y = 10
Answers
Answer:
(2, 4)
Step-by-step explanation:
y = x + 2
3x + y = 10
3x + (x + 2) = 10
4x + 2 = 10
4x = 8
x = 2
y = (2) + 2
y = 4
Step-by-step explanation:
3x + y = 10
substituting the value of y = x + 2
=>3x + x+2 = 10
=>4x= 10-2
=>4x= 8
=>x= 8/4
=>x= 2
And, y= 2+2 = 4

Divide by .20
a = 11/.20

Answer:
B. 66 m
Step-by-step explanation:
Map and ground distances are proportional:
ground/map = ground/(12 cm) = (11 m)/(2 cm)
ground = (12 cm)(11 m/(2 cm)) = 66 m
The distance from A to B is 66 m.

The systolic blood pressure (BP) of adults in the USA is nearly normally distributed with a mean of 121 and standard deviation of 16 . Someone qualifies as having Stage 2 high blood pressure if their systolic blood pressure is 160 or higher. (a) Around what percentage of adults in the USA have stage 2 high blood pressure
Answers
Answer:
Around 0.73% of adults in the USA have stage 2 high blood pressure
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.
Mean of 121 and standard deviation of 16.
This means that [tex]\mu = 121, \sigma = 16[/tex]
Around what percentage of adults in the USA have stage 2 high blood pressure
The proportion is 1 subtracted by the p-value of Z when X = 160. So
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]Z = \frac{160 - 121}{16}[/tex]
[tex]Z = 2.44[/tex]
[tex]Z = 2.44[/tex] has a p-value of 0.9927.
1 - 0.9927 = 0.0073
0.0073*100% = 0.73%
Around 0.73% of adults in the USA have stage 2 high blood pressure
