Answer 1

Answer:

4.That first one sounds familiar; I think I did it yesterday.

The sides don't matter (except that they're equal) so the base angle b satisfies

b + b + 38 = 180

2b = 142

b = 71

Choice a

42 + 42 + v = 180

v = 180 - 84 = 96

choice d

6. That's three acute angles, an acute triangle

7. We need to satisfy the triangle inequality which means the sum of the two smaller sides needs to be bigger than the largest

10+15>24 so choice b

SRT = RTS = 180 - STU

3x - 50 = 180 - 7x

10 x = 230

x = 23

choice a

Ten people at a party decide to compare ages. Five people are 30 years old, three are 32, one is 31, and one is 65. To illustrate the importance of outliers, suppose the 65-year old walks away from the party. Remaining at the party are the five people who are 30 years old, three people that are 32, and one person that is 31.
Determine the mean age and standard deviation, to the nearest tenth, of the people who remain at the party.
A. The mean age of the remaining people at the party is a0
B. The standard deviation is:

Answers

Given:
Ten People
5 people = 30 years old
3 people = 32 years old
1 person = 31 years old
1 person = 65 years old

We need to arrange the ages in order from least to greatest.

30, 30, 30, 30, 30, 31, 32, 32, 32, 65
65 is the outlier.

A.) mean age without the outlier. count of the numbers : 9
5 x 30 = 150
1 x 31 = 31
3 x 32 = 96
total age 277
÷ # of pax 9
mean 30.77 round to the nearest tenth 30.80

b.) Standard deviation:
We need to calculate variance first:
5 pax : 30 - 30.80 = - 0.80 ⇒ -0.80² = 0.64 * 5pax = 3.20
1 pax : 31 - 30.80 = 0.20 ⇒ 0.20² = 0.04 * 1pax = 0.04
3 pax : 32 - 30.80 = 1.20 ⇒ 1.20² = 1.44 * 3 pax = 4.32

Variance : (3.20 + 0.04 + 4.32) / 9 pax = 7.56 / 9 = 0.84

Standard deviation is simply the square root of the variance.

Standard deviation = √0.84 = 0.916

0.916 round to nearest hundredths is 0.92
0.916 round to nearest tenths is 0.90

Using only five odd numbers, add them up so that the result is 32, the five odd numbers have to be whole numbers only.

Answers

This is not possible. If you add an odd number of odd numbers, you will get an odd number. If you add an even number of odd numbers, you will get an even number. 5 is an odd number, but 32 is an even number, so therefore it is not possible.

Which represents the polynomial written in standard form?

4m – 2m4 – 6m2 + 9

Answers

Answer:

Step-by-step explanation:

Alright, lets get started.

The given polynomial is : $4m-2m^4-6m^2+9$

In the standard form, the highest power term is written first

Then second highest power is written and follows the same rule further

Here the highest power term is $-2m^4$

The second highest power term is $-6m^2$

The third highest power term is $4m$

Last term is 9

So, the standard form is :

$-2m^4-6m^2+4m+9$ : Answer

Which is more?
1. Riding a bike 10 miles in 1 hour
2. Jogging 3 miles in 24 minutes

Answers

I say that number one is more reasonable but 10 miles in one hour, compared to 3 miles in 24 minuets
and 3*3 = 9
which is close to ten and
24 * 3 = 72 minuets
there are 60 minuets in an hour
so i would say the second option is correct :)
