Basil has five numbered cards.
Two of the numbers are hidden. 4 9 9 ? ? 8
The mode of the five numbers is 8.
The mean of the five numbers is 6
c) Work out the two hidden numbers.
Answer:
The two hidden numbers are 8 and 1.
Step-by-step explanation:
Mean of a data-set:
The mean of a data-set is given by the sum of all its values divided by the number of values.
Mode of a data-set:
The mode of a data-set is the value that appears the most.
In this question:
4, 9, x, y, 8
Mode is 8 means that at least one of them must be 8, so i will say x is 8 and we have:
4, 9, 8, y, 8
The mean of the five numbers is 6
This means that:
[tex]\frac{4+9+8+y+8}{5} = 6[/tex]
[tex]29+y = 30[/tex]
[tex]y = 30 - 29[/tex]
[tex]y = 1[/tex]
The two hidden numbers are 8 and 1.

If f(x)=x+5, what is f-'(x)?
Step-by-step explanation:
Given
f(x) = x + 5
Let
y = f(x)
y = x + 5
Interchanging the roles of x and y we get
x = y + 5
y = x - 5
f^-1 (x) = x - 5

Renee and Thomas live at the beach and collect seashells. The number of shells Renee collects on any given day, R, is approximately Normal with a mean of 58.2 shells and a standard deviation of 12.8 shells. The number of shells Thomas collects on any given day, T, is approximately Normal with a mean of 47.9 shells and a standard deviation of 11.5 shells. Assume the two random variables are independent of each other. What is the probability that on a randomly selected day the total number of shells collected by Renee and Thomas is 120 or more? 0.002 0.209 0.284 0.791

14=s/3 what does s equal
===============================================
Explanation:
To isolate s, we need to undo the division. We'll multiply both sides by 3
14 = s/3
3*14 = 3*(s/3)
42 = s
s = 42
-------
As a check,
14 = s/3
14 = 42/3 .... replace s with 42
14 = 14
We get the same thing on both sides, so this confirms we have the correct value of s.

Given: x = 11 when y = 99. If y varies directly as x, find x when y= 144
Answer:
x=16
Step-by-step explanation:
11×9=99, so variaton is 9x=y. that means y=x/9
144/9=16

sin0=? cos0=? tan1=?
Answer:
See explanations below
Step-by-step explanation:
Sin 0 = x
0 = arcsinx
Since 0 the angle is positive and lies in the 1st and second quadrant, sin 0 = 0 (in the first quadrant)
cos 0 = 1 (by punching the calculator)
tan 1 = 0.0174
All this values can easily be gotten directly from calculators

Elaina charged $83 on her credit card to buy groceries. If the
balance is now $294, what was the balance before she bought
groceries?
Answer:
211?
Step-by-step explanation:
I'm not sure if this is correct, but:
294-83=211.
Hope this helps! :)
The balance before she bought the groceries was $277.
What are mathematical operations?In mathematics, an operation is a function which takes zero or more input values (also called "operands" or "arguments") to a well-defined output value.There are five fundamental operations in mathematics: addition, subtraction, multiplication, division, and modular formsGiven is that Elaina charged $83 on her credit card to buy groceries. The balance is now $294.
The balance before she bought the groceries is -
294 + 83
277
Therefore, the balance before she bought the groceries was $277.

Write the equation of a parabola in factored form if the x-intercepts are (3,0) and (-5,0) with a maximum point at ( -1,8)
Answer:
y = - [tex]\frac{1}{2}[/tex] (x - 3)(x + 5)
Step-by-step explanation:
Given the x- intercepts are x = 3 and x = - 5 then the corresponding factors are
(x - 3) and (x + 5)
The equation is the the product of the factors, that is
y = a(x - 3)(x + 5) ← a is a multiplier
To find a substitute (- 1, 8) into the equation
8 = a(- 1 - 3)(- 1 + 5) = a(- 4)(4) = - 16a ( divide both sides by - 16 )
- [tex]\frac{1}{2}[/tex] = a
Then
y = - [tex]\frac{1}{2}[/tex] (x - 3)(x + 5) ← in factored form
