LM=2x+24
MN= x+28
LN=31
LN=(2x+24)+(x+28)
31=(2x+24)+(x+28)
solve
31=(2x+24)+(x+28)
31-24-28 = 2x +x

Find the value of zα/2 to construct a confidence interval with level 95%. Round the answer to two decimal places.
Answers
Answer:
The value is [tex]Z_{\frac{\alpha }{2} } = 1.96[/tex]
Step-by-step explanation:
From the question we are told the confidence level is 95% , hence the level of significance is
[tex]\alpha = (100 - 95 ) \%[/tex]
=> [tex]\alpha = 0.05[/tex]
Generally from the normal distribution table the critical value of [tex]\frac{\alpha }{2}[/tex] is
[tex]Z_{\frac{\alpha }{2} } = 1.96[/tex]

A professional language translator gets paid an average of $320 per hour with a standard deviation of $41.75 per hour. What proportion of professional language translators get paid less than $250 per hour? Assume the population is normally distributed. Round your answer to four decimal places
Answers
Answer:
0.0475 or 4% professional language translators get paid less than $250 per hour
Step-by-step explanation:
Mean = 320
Standard Deviation = 41.75
We need to find proportion of professional language translators get paid less than $250 per hour i.e P(x<250)
First we will find value of z
Using formula: [tex]z=\frac{x-\mu}{\sigma}[/tex]
We have x=250, finding z
[tex]z=\frac{x-\mu}{\sigma}\\z=\frac{250-320}{41.75}\\z=-1.67[/tex]
Now we will find P(z<-1.67) by looking into the normal distribution table
[tex]P(z<-1.67)=0.0475\\[/tex]
So,0.0475 or 4% professional language translators get paid less than $250 per hour

Answers
Answer:
78% of the children can swim
Step-by-step explanation:
There are 50 children, 11 of them cannot swim. The fraction of children that cannot swim is 11/50. We have to change that into a percentage.
11/50 x 2 will equal our percentage
11 x 2 = 22
50 x 2 = 100
22/100 or 22%
We have the percentage of the children who cannot swim, now we have to find the percentage of children who can swim.
100% - 22% = 78%

Input in standard form the equation of the given line. The line that passes through (-3, 5) and (-2, -6)
Answers
Answer:
The equation in standard form is 11x + y = -28.
Step-by-step explanation:
Let's start with y = mx + b
5 = -3m + b
-6 = -2m + b
Let's take the second less the first.
m = -11
Plug back in the first equation to calculate b.
5 = 33 + b
b = -28
So y = -11x - 28
11x + y = -28
23) It takes a bus 6 hours to take a trip. The train takes only 4 hours to make the same trip. The train travels
at a rate of speed that is 25 mph more than the speed of the bus. What is the rate of the bus and the rate of
the train? State what x represents, state the equation, and then state the answer.
Rate Time Distance
Bus x 6 бах
Train x-? 2(x+3)
Distance bus travels – Distance train travels
Answers
Answer:
x = 50 mph speed of the bus
y = 75 mph speed of the train
Step-by-step explanation:
Lt´s call "x" speed of bus and "y" speed of train.
According to the problem statement
6*x = 4*y (1)
y = x + 25 (2)
We solve for x and y the two equation system
y = ( 6/4)*x
( 6/4)*x = x + 25
6*x = 4*x + 100
2*x = 100
x = 50 mph
And
y = (6/4)*x
y = 300/4
y = 75 mh

Step-by-step explanation:
The number of ways in which the word 'PHILOSOPHY' can be arranged is 453,600.
What is a factorial?The product of a whole number 'n' with every whole number until 1 is called the factorial. The factorial of 4 is, for example, 43221, which equals 24.
As we can see that the word 'PHILOSOPHY' has 10 letters therefore, the letters of the word can be arranged in the 10! manner, but it contains the letter P, H and O twice therefore, there will be words that will look the same and are counted twice. Thus, the number of ways the word PHILOSOPHY can be arranged are,
[tex]\text{Number of ways} = \dfrac{10!}{2! \times 2! \times 2!} = 453,600[/tex]
Hence, the number of ways in which the word 'PHILOSOPHY' can be arranged is 453,600.
