Answer:
49 pizzas
Step-by-step explanation:
Start by writing it as a equation,
P stands for Pizza
6p +97 = 8p
Minus 6p from both sides
97=2p
Divide by 2
P= 48.5
You would need to round up, so it would be 49 pizza
Complete Question
The SAT are scored so as to yield a mean of 500 and a standard deviation of 100. These scores are close to being normally distributed. An exclusive club wishes to invite those scoring in the top 5% on the College Boards to join. a. Find percentages of scores that is between 480 and 590. b. What score is required to be invited to join the club? c. What score separates the top 60% of the population from the bottom 40%? What do we call this value? (hint: the score that separates the top 20% of the population from the bottom 80% is called the 80th percentile)
Answer:
a
b
c
The value is called the percentile
Step-by-step explanation:
From the question we are told that
The mean is
The standard deviation is
Generally the percentage of the score that are between 480 and 590 is mathematically represented as
Here
=>
=>
=>
From the z table (reference calculator dot net )
And
=>
=>
Converting to percent
The percentage invited to join the club is the top 5% , this can be mathematically represented as
Here x is the score that is within the top 5%
=>
Generally the critical value of 0.05 from the normal distribution table is
So
=>
=>
Generally the probability of having a score that separates the top 60% of the population from the bottom 40%
=>
The critical value of 0.60 from the normal distribution table is
So
=>
From the hint given we can see that this value is called the percentile
Answer:
The answer is
<h2>660.5 square feet</h2>
Step-by-step explanation:
Area of a circle = πr²
where r is the radius
From the question
diameter = 29 feet
To find the radius given the diameter we use the formula
So the area of the circle is
We have the final answer as
<h3>660.5 square feet</h3>
Hope this helps you
<h2>
Answer: y = - ⁵/₂ x + 8 OR y - 8 = -⁵/₂ x</h2>
<h3>
Step-by-step explanation:
</h3>
<u>Finding the Equation</u>
We can now use the point-slope form (y - y₁) = m(x - x₁)) to write the equation for this line:
⇒ y - 8 = -⁵/₂ (x - 0)
y - 8 = -⁵/₂ x
we could also transform this into the slope-intercept form ( y = mx + c)
since y - 8 = - ⁵/₂ x
⇒ y = - ⁵/₂ x + 8

Answer:
You cannot simplify this problem down anymore; it is at its simplest form.
Step-by-step explanation:
You cannot add together x^4 and x^2 due to the simple fact that they do not share similar exponents.
For example you could add together x^4 and x^4 to get 2x^4. But you cannot add x^4 and x^2.
