Answer:
Mean = 58.18
Median = 60
Modes = 55 and 60
Step-by-step explanation:
To find the mean/average, add up all the numbers and divide the sum by the # of numbers there are (ex. there are 11 numbers so divide the sum by 11).
The median is the middle number of a set. In this case, the middle number is easy to see because the # of numbers is odd, but if it was even, just find the average of the two middle numbers.
The mode is/are the most frequent number(s) in the set. In this set, the numbers that appear the most are 55 and 60.

Find the lest number which is exactly divisible by 36 & 90 Maths
Answer:
180Step-by-step explanation:
You need to find the HCF of 36 and 90.
Prime factors of each:
36 = 2*2*3*390 = 2*3*3*5HCF includes all prime factors of both numbers:
HCF(36, 90) = 2*2*3*3*5 = 180To find the least number,
Which is exactly divisible by 36 and 90. We have to find the HCF of 36 and 90.
→ 36 = 2 × 2 × 3 × 3
→ 90 = 2 × 3 × 3 × 5
Then the required HCF will be,
→ 2 × 2 × 3 × 3 × 5
→ 180 (HCF)
Thus, 180 is the least number which is exactly divisible by 36 and 90.
My nephew needs help with this question
The domain is the set of all the x-values/inputs used by the function.
The range is the set of all y-values/outputs used by the function.
For #1:
The domain is { 1, 0, -1, 4 } because those are the x-values.
The range is { 3, 5, 7, -6 } because those are the x-values.
I'll let you try #2. if you write back with your answer, I'll reply to let you know if you did it correctly.
sin(60-theta)sin(60+theta)
Step-by-step explanation:
[tex] \sin(60 - \theta) \sin(60 + \theta) \\ = \{ \sin(60) \cos( \theta) - \sin( \theta) \cos(60) \} \{ \sin(60) \cos( \theta) + \cos(60) \sin( \theta) \} \\ = \{ \frac{ \sqrt{3} }{2} \cos( \theta) - \frac{1}{2} \sin( \theta) \} \{ \frac{ \sqrt{3} }{2} \cos( \theta) + \frac{1}{2} \sin( \theta) \} \\ \\ [/tex]
from difference of two squares:
[tex]{ \boxed{(a - b)(a + b) = ( {a}^{2} - {b}^{2} ) }}[/tex]
therefore:
[tex] = \{ {( \frac{ \sqrt{3} }{2}) }^{2} { \cos }^{2} \theta \} - \{ {( \frac{ \sqrt{3} }{2} )}^{2} { \sin }^{2} \theta \} \\ \\ = \frac{3}{4} { \cos }^{2} \theta - \frac{3}{4} { \sin}^{2} \theta[/tex]
factorise out ¾ :
[tex] = \frac{3}{4} ( { \cos }^{2} \theta - { \sin}^{2} \theta) \\ \\ = { \boxed{ \frac{3}{4} \cos(2 \theta) }}[/tex]

Audrey works in a factory. She receives a salary of $10 per hour and piecework pay of 15 cents
per unit produced. Last week she worked 38 hours and produced 755 units.
a. What was total hourly pay for the week?

Sentence
b.what was her total pay for the week?
(whoever responds first gets a crown!)
Answer:
A. total hourly pay $380.00 &
B. total pay for the week $493.25
Step-by-step explanation:
38 hours x $10 per hour = 380.00
755 unit products x .15 = 113.25
380 hourly pay + 113.25 unit pay = 493.25

On a number line what is the distance between -3/2 and 6?
Answer:
7.5 unitsStep-by-step explanation:
The distance is always positive and is same as the absolute value of subtraction of the two numbers on the line.
This can be shown as:
|-3/2 - 6| = |-1.5 - 6| =|-7.5| = 7.5or
| 6 - (-3/2)| = |6 + 1.5| = |7.5| = 7.5Answer:
15/2 or 7.5
Step-by-step explanation:
Distance = x_2 - x_1
Distance = 6 - (-3)/2
Distance = 6 + 3/2
Distance = 12 + 3/2
Distance = 15/2 or 7.5
An unknown polynomial is added to the expression -3x^3+2x-5 and the resulting sum is 4x^3+7x^2-3. what is the unknown polynomial?
Answer:
7x³ + 7x² + 2x - 8
Step-by-step explanation:
Let the unknown polynomial be a
a + -3x³ + 2x - 5 = 4x³ + 7x² - 3
a = 4x³ + 7x² - 3 - (-3x³ + 2x - 5)
a = 4x³ + 7x² - 3 + 3x³ + 2x - 5
a = 7x³ + 7x² + 2x - 8

there are 45 students in a speech contest. Yesterday, 2/3 of them have their speeches. Today, 3/5 of the remaining students give their speeches. How many students still haven't given their speeches?
Answer:6 students remaining
Step-by-step explanation:Multiply 2/3 *45 which equals 30. If 30 students gave their speech on the first day there are 15 students remaining. Then multiply 3/5 * 15 which equals 9. If 9 of the 15 remaining students gave their speech than 15-9= 6 students remaining.

Select the correct choice below and, if necessary, fill in the answer box to complete your choice.
O A. -0.5•(-0.4) =
B. The expression is undefined
(Answer quickly)
To multiply numbers or expressions means that we calculate the product of the numbers or expressions. The value of [tex]-0.5 \times (-0.4)[/tex] is [tex]0.2[/tex]
Given that:
[tex]-0.5 \times (-0.4)[/tex]
Cancel out the negative signs
[tex]-0.5 \times (-0.4) = 0.5 \times (0.4)[/tex]
Using a calculator, we have:
[tex]-0.5 \times (-0.4) = 0.2[/tex]
Hence, the value of [tex]-0.5 \times (-0.4)[/tex] is [tex]0.2[/tex]

-2 (3y + 2) - 7z - 4(3z+ 8y )
how do you simplify expression with distribution?
Answer:
-38y - 19z - 4
Step-by-step explanation:
You meses to multiply the numbers outside the brackets with the values inside.
First you have -2(3y+2) so you multiply -2 with 3y = -6y and then you multiply the -2 with the +2 = -4. So you're left with -6y - 4 - 7z - 4(3z+8y).
Now do the same with the last one, multiply -4 by 3z = -12z, then multiply -4 with +8y = -32y. You're left with -6y-4-7z-12z-32y.
Now we change the order to make it easier and we have -32y-6y-12z-7z-4, we make the subtractions and we get -38y - 19z - 4
