Step-by-step explanation:
Isolate the variable by dividing each side by factors that don't contain the variable.
F(x)=x^2-x^3 find the value of f(-2)
The Correct answer is 3
Explanation:
Using the defined function, f(a) will produce the same result when substituted for x:
F(x)=x^2-x^3
Setting this equal to 4, you can solve for a:
a2 – 5 = 4
a2 = 9
a = –3 or 3
The standard deviation of the following data set is 0.31. 68% of the data would fall in which range?
4.3, 5.1, 3.9, 4.5, 4.4, 4.9, 5.0, 4.7, 4.1, 4.6, 4.4, 4.3, 4.8, 4.4, 4.2, 4.5, 4.4
Answer:
Pr(4.19 ≤ X ≤ 4.81)
Step-by-step explanation:
First of all, let's calculate the mean;
x¯ = (4.3 + 5.1 + 3.9 + 4.5 + 4.4 + 4.9 + 5.0 + 4.7 + 4.1 + 4.6 + 4.4 + 4.3 + 4.8 + 4.4 + 4.2 + 4.5 + 4.4)/17
x¯ = 76.5/17
x¯ = 4.5
We are given standard deviation; s = 0.31
Now, z-value for a 68% Confidence interval is 1
Range in which the data falls is;
Range = x¯ ± zs
Range = 4.5 ± (1 × 0.31)
Range is;
Pr[(4.5 - 0.31) ≤ X ≤ (4.5 + 0.31)]
Pr(4.19 ≤ X ≤ 4.81)
Answer:
Pr (3.57 ≤ X ≤ 5.43)

A canteen spends money on food and drink in the ratio of 29:3
In total, they spend £6496.
Find how much money they spend on drink.
Answer:
Money spend on drink = £ 609
Step-by-step explanation:
Food : drink = 29 : 3
Money spend on food = 29x
Money spend on drink = 3x
Total money spend = 29x + 3x = 32x
32x = £6496
x = 6496/32
x = £ 203
Money spend on drink = 3x = 3 * 203 = £ 609

Given:
In a sale,
a blow-dryer is marked down from $18.98 to $11.39.
Let n be the percent decrease.
So,
n = 11.39 x 100/18.39
n = 61.94
Therefore, the required percentage is 61.94%.

Find the slope and the y-intercept of the graph of the linear equation.
y+7=5/4x
The slope is
and the y-intercept is
Answer:
your slope would be 5/4
Step-by-step explanation:
your x will always be your slope. when you rewrite the equation it would be
y=5/4x-7
so from -7 you would go up 5 and over 4.
Again your x value will always be your slope.

A water slide starts at (0,144) and ends at (12,0) what is the slope of the slide
Answer:
-12
Step-by-step explanation:
The slope of a line is just the difference of y-values divided by the difference of x-values

Answer:
[tex]a_{n}[/tex] = 4n + 4
Step-by-step explanation:
There is a common difference d between consecutive terms in the sequence.
d = 12 - 8 = 16 - 12 = 20 - 16 = 4
This indicates the sequence is arithmetic with n th term
[tex]a_{n}[/tex] = a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Here a₁ = 8 and d = 4 , then
[tex]a_{n}[/tex] = 8 + 4(n - 1) = 8 + 4n - 4 = 4n + 4
