in a standard normal distribution, the probability that z is greater than zero is
Answer:
50%
Step-by-step explanation:
The distribution is symmetrical about the y-axis.
The probability that z is greater than zero in a standard normal distribution is 0.5 or 50%.
What is Probability?The branch which deals with the occurrence of a random event is known as probability.
The area under the curve to the right of z = 0 is equal to the area under the curve to the left of z = 0. So the standard normal distribution is symmetric about the mean of zero
As the total area under the curve is equal to 1, each of these areas must be 0.5 or 50%.
In a standard normal distribution, the probability that z is greater than zero is 0.5, or 50%.
Therefore, the probability that z is greater than zero in a standard normal distribution is 0.5 or 50%.

In London. I pint of milk costs 58p.
In Paris, 1 litre of milk costs 1.05 euros.
1 litre = 1.76 pints
£1 = 1.17 euros
In which city is the milk better value for money, London or Paris?
You must show your working.
Comparing the equivalent cost of Milk in Euro in the two countries, then we can conclude that Milk is a better value for money in Paris.
In other to make accurate comparison of the cost ; we need to using the same unit or milk and same currency value :
Cost of 1 pint of Milk in London :
1 pint = 0.58 pounds
The equivalent value of 1 pint of Milk in terms of Euro in London will be :
1 pound = 1.17 euro
0.58 pound = x
Cross multiply :
x = 1.17 × 0.58
x = 0.6786 euro
x = 0.68 euro
Hence, 1 pint of Milk cost 0.68 euro in London
Cost of 1 pint of Milk in Paris :
1 Litre = 1.76 pint
Hence,
1.76 pint = 1.05 euro
1 pint = c
1.76c = 1.05
c = 1.05 / 1.76
c = 0.597 euro
Hence, cost of 1 pint of Milk cost 0.60 euro in Paris
Therefore, since the cost of Milk in Paris cost less in Paris than in London, then Milk is a better value for money in Paris.

Step-by-step explanation:

1) say you are given the graph of the line y =- x write the equation of the line that is parallel to the given line and goes through the point (-8,2)
2) say you are given the graph of the line y =- x write the equation of the line that is parallel to the given line and goes through the point (8,2)
I'm pretty sure the answer to y=−x. Write equation for (8,2) is y=x-6. The opposite of the x is -8, hence, (-8,2) is y=-x-6 is the answer
1. The equation of the line which is parallel and goes through the point (-8, 2) is,
y = x + 10
2. The equation of the line which is parallel and goes through the point (8, 2) is,
⇒ y = x - 6
What is Equation of line?
The equation of the line in slope-intercept form is expressed as:
y - y₁ = m(x - x₁)
where: m is the slope.
and (x₁, y₁) is the point on the line.
1. Given that;
Equation of the line as y = -x
Get the slope of the line,
y = -x
m = -1
Since, The required line is parallel to this line,
So, the required slope will be -1
Now, Get the required equation as,
y - y₁ = m(x - x₁)
y - 2 = 1 ( x - (-8) )
y - 2 = x + 8
y = x + 8 + 2
y = x + 10
Hence, The equation of the line which is parallel and goes through the point (-8, 2) is,
⇒ y = x + 10
2. Given that;
Equation of the line as y = -x
Point as (8, 2)
Get the slope of the line,
y = -x
m = -1
Since, The required line is parallel to this line,
So, the required slope will be -1
Now, Get the required equation as,
y - y₁ = m(x - x₁)
y - 2 = 1 ( x - 8 )
y - 2 = x - 8
y = x - 8 + 2
y = x - 6
Hence, The equation of the line which is parallel and goes through the point (8, 2) is,
⇒ y = x - 6
Thus,
1. The equation of the line which is parallel and goes through the point (-8, 2) is,
y = x + 10
2. The equation of the line which is parallel and goes through the point (8, 2) is,
⇒ y = x - 6

What is a Turning Point of a Function?The turning point of a function is defined as the point where the graph of the function changes it's form. That is, an increasing graph changes to decreasing at that point and vice versa.
Given a table values of function.
Also, given that, one of the turning point is at x = -1.
At x = -1, f(x) = 4.
After it, the function decreases.
We can also see another turning point at x = 1.
At x = 1, f(x) = -4.
After x = 1, the function again increases to get the value f(x) = -2.
So x = -2 is not a turning point.
So the value of f(-2) = m lies in between -12 and 4.
Hence the correct option is B.

Answer:
$513.75
Step-by-step explanation:
Let h represent the number of hours he worked in a week
An auto mechanic earns $498.75 in 35 hours during the week. His pay is $2.50 more per hour on weekends.
Hence, his pay Is represented by equation:
$498.75 + $2.50 × x
If he works 6 hours on the weekend in addition to the 35 hours during the week
$498.75 + $2.50 × 6
= $498.75 + $15
= $513.75
Therefore, he earns $513.75

7/1 − 3 ( 7/3n − 7/2 )
Answer:
[tex]\frac{35}{2}[/tex] - [tex]7n[/tex]
Step-by-step explanation:
7/1 − 3( 7/3n − 7/2 )
Anything divided by one gives itself.
7 - 3 ( [tex]\frac{7}{3}n - \frac{7}{2}[/tex])
Use the distributive property to multiply −3 by [tex]\frac{7}{3}n - \frac{7}{2}[/tex])
7 - 3 × ([tex]\frac{7}{3}[/tex][tex]n[/tex] - 3 (-[tex]\frac{7}{2}[/tex])
Multiply −3 times [tex]\frac{7}{3}[/tex]
7 - 7n - 3 (-[tex]\frac{7}{2}[/tex])
Express -3 (-[tex]\frac{7}{2}[/tex]) as a single fraction.
7 - 7n + [tex]\frac{-3(-7)}{2}[/tex]
Multiply −3 and −7 to get 21.
7 - 7n + [tex]\frac{21}{2}[/tex]
Convert 7 to fraction [tex]\frac{14}{2}[/tex]
[tex]\frac{14}{2}[/tex] - 7n + [tex]\frac{21}{2}[/tex]
Since [tex]\frac{14}{2}[/tex] and [tex]\frac{21}{2}[/tex] have the same denominator, add them by adding their numerators.
[tex]\frac{14 + 21}{2} - 7n[/tex]
Add 14 and 21 to get 35.
[tex]\frac{35}{2} - 7n[/tex]
