3 tbsp mayonnaise is how many servings of oil?
Answers
Therefore each song costs $20/16 = $5/4 = $1.25
So:
2 songs would cost 2 * $1.25
3 songs would cost 3 * $1.25
...
x songs would cost x * $1.25
Since Renata started with $20, then her balance (y) after buying x songs would be:
y = 20 - 1.25*x
The equation that represents the relationship between the remaining balance and the number of songs purchased is y = $20 - $1.25x.
What is the equation?
The first step is to determine the cost of one song.
Cost of one song = $20 / 16 = $1.25
Remaining balance = value of the gift card - (number of songs purchased x cost of one song)
y = $20 - $1.25x

Answer:
NO Solution
Step-by-step explanation:
First, from the first equation let's move the Y term to the other side to match with the second equation.
Now lets compare the two equations.
Since the left sides are the same but the right sides of the equations aren't, we can see there are no solutions to this system.

The value of x in the expression 7x-3=5x+5 is 4
Given
7x-3=5x+5
Here,
The equation is linear in variable x .
7x-3=5x+5
7x - 5x - 3 = 5
2x-3=5
2x = 5 + 3
2x=8
x = 8/2
x=4
Thus the value of x is 4 .

What percent of humans have a temperature between 36.6°c and 37.4°c?
Which normal curve is shaded correctly for this problem?
Answers
Answer: Choice B
Explanation:
Let's convert the raw score x = 36.6 to its corresponding z score.
z = (x-mu)/sigma
z = (36.6 - 37)/(0.2)
z = -2
Note that mu and sigma represent the mean and standard deviation respectively. The score z = -2 means we're 2 standard deviations below the mean.
Following those similar steps, you should find that x = 37.4 leads to z = 2.
The temperatures we're focused are on the interval , i.e. the z values are between -2 and 2 inclusive.
Therefore, the range of temperatures are within 2 standard deviations of the mean.
Visually, we'll go for choice B since this shows the lower two sections shaded (ie the panels to the left of the center) and also the upper two sections shaded. According to the Empirical Rule, this accounts for roughly 95% of the normal distribution.
