Answer:
0.9962
Step-by-step explanation:
The z score shows the number of standard deviations by which the raw score is above or below the mean. If the raw score is above the mean then the z score is positive but if the raw score is less than the mean then the raw score is negative. The z score is given by:
μ = 20.66°C, σ = 2°C
For x < Singapore temperature, i.e. x < 26
From the normal distribution table P(x < 26) = P(z < 2.67) = 0.9962
Answer:
-3
Step-by-step explanation:
First, we have to do -9 + 6.
The order of addition does not matter, so we can switch around the numbers, making the statement:
6+ (-9)
If this is the equation, we can cancel out the addition sign:
6-9
Now we have to subtract 9 from six, and we will get -3.
x = -3
The table below is a quadratic function.
<h3>What is a quadratic function?</h3>
A quadratic function is an Algebraic function with the power of its variable as 2.
This function normally has three algebraic terms, the x-square term, the x-term and the constant term.
Analysis:
The X-column values increases from -2 to 1, while the f(x) column which is the y-column increase from -9, until it gets to 1, where the value falls to -5.
A typical behavior of an inverted-v curve which is a quadratic curve.
If it were a linear function, as x values increase, y value would either keep increasing or decreasing, it does not change its orientation.

Answer:
d is the answer to your question
Answer:
5w/17
10 books
Step-by-step explanation:
Initial Amount had = $6w
Cost per book = $17
Amount had after book purchase = $w
The number of books purchased :
(Initial amount had - amount had after purchase) / cost per book
($6w - $w) / $17
$5w / $17
Number of books purchased = 5w/17
B.) if w = 34
Number of books purchased :
(5*34) / 17
= 170 / 17
= 10 books
