Answer:
140 squirrels
Step-by-step explanation:
first week, there are 5 squirrels.
second week, there are 8 squirrels.
third week, there are 11 squirrels.
let's calculate the amount of squirrels at the end of 28 weeks. from the statement given, an addition of 3 squirrels for every week.
by cross multiply method:
5 squirrels = 1 week
x squirrels = 28 weeks
x = 28 x 5
x = 140 squirrels.
so you will have an amount of 140 squirrels after 28 weeks.
what is at the end of a rainbow
Answer:
A pot of Gold supposedly with a leprechaun next to it
Step-by-step explanation:
Answer:
You can't reach the end of the rainbow because a rainbow is kind of like an optical illusion. A rainbow is formed because raindrops act like little prisms. So no matter how you move, the rainbow will always be the same distance away from you. That's why you can never reach the end of the rainbow.

Answer: Choice D)
He needs to square each deviation in the numerator.
==========================================================
Explanation:
The sample standard deviation involves these steps
Find the sample mean xbar.Subtract the xbar value from each data point. This gets us the list of deviations or how far each person is from the mean.Square each difference in the previous stepAdd up the squares from step 3. This is referred to as the Sum of the Squared Errors (SSE)Divide the SSE over n-1. If Toby was doing a population standard deviation, then he'd divide over n instead of n-1. However in much of statistics, we don't know much about a population and instead rely on sample statistics.The result of step 5 gets the variance. Apply the square root to the variance to get the standard deviation.The step 3 highlighted in bold is where Toby made an error. He subtracted xbar from each person correctly, but forgot to square those deviations. The squaring is done to ensure we don't have any negative deviations.
This is what his work should look like when calculating the sample standard deviation

O D. 2 kg > 1000 g/kg *

x 4.186 kJ/mol = 465 kJ
The energy that it takes to melt 2 kg of ice is; (2 kg * 1000 g/kg) * 1 mol/18.02 g * 6.03 kJ/mol = 669 kJ
What is the energy required?
We are given;
Mass of ice; m = 2 kg
Now, from tables showing constants for ice, we see that;
Molar heat of fusion for ice; Δ_fus.H = 6.03 kJ/mol at 0°C.
Molar mass of Ice which is water is; 18.02 g/mol
Formula to get the energy is;
E = (m/M) * Δ_fus.H
E = (2 kg * 1000 g/kg) * 1 mol/18.02 g * 6.03 kJ/mol = 669 kJ

How many heads would you expect if you flipped a coin twice? first, fill in the table below with the correct probabilities. hint: the sample space for flipping a coin twice is {hh, ht, th, tt}. a 4-column table has 2 rows. the first column has entries number of heads and probability. the second column has entries 0, a. the third column has entries 1, b. the fourth column has entries 2, c. a = b = c =
The value which is expected for the number of heads when a coin is flipped twice is 1. The value of a, b, and c is 0.25, 0.50, and 0.25 respectively.
What is probability?Probability of an event is the ratio of number of favorable outcome to the total number of outcome of that event.
The 4-column 2 rows table which shows the number of heads and probability of that is shown below.
Heads 0 1 2
Probability. a b c
When a coin is flipped two times, then we get the four outcomes. The sample space for flipping a coin twice is,
[tex]{HH, HT,TH, TT}[/tex]
Here, the H represent the head and T represent the tail. Only one time in four events there is no head appear. In this sample space, the probability of 0 heads both the time is,
[tex]P_0=\dfrac{1}{4}=0.25[/tex]
The 1 head appears twice in the sample space (HT, TH). Thus, the probability of 1 heads both the time is,
[tex]P_1=\dfrac{2}{4}=0.50[/tex]
On both flip, head appears a single time in the sample space (HH). Thus, the probability of 2 heads both the time is,
[tex]P_2=\dfrac{1}{4}=0.25[/tex]
The new table for these values is attached below.
Hence, the value which is expected for the number of heads when a coin is flipped twice is 1. The value of a, b, and c is 0.25, 0.50, and 0.25 respectively.

720 students took part in the survey. Only 45% were female.
How many males took part in the survey?
Answer:
396 males
Step-by-step explanation:
First, let's find the percentage of males who took part in the survey.
100% - 45% = 55%.Now, let's find 55% of 720.
Step 1: Multiply 55 by 720
55 × 39600Step 2: Divide 39,600 by 100.
39600/100396 malesHave a lovely rest of your day/night, and good luck with your assignments! ♡
The number of males took part in the survey is 396.
What is percentage?Percentage is defined as a given part or amount in every hundred. It is a fraction with 100 as the denominator and is represented by the symbol "%".
Given that, 720 students took part in the survey.
Only 45% were female.
So, the number of females = 45% of 720
= 45/100 ×720
= 0.45×720
= 324
So, number of males = 720-324
= 396
Therefore, the number of males took part in the survey is 396.

The ratio of the measure of two supplementary angles is 15:21. What is the measure of the smallest angle?
Answer:
75
Step-by-step explanation:
The measure of two supplementary angles = 15:21
The angles are 15x , 21x
15x + 21x = 180 {Supplementary}
36x = 180
x = 180/36
x = 5
Smallest angle = 15 * 5 = 75

6. What is the measure of each exterior angle
of a regular decagon?
a.45°
B.36°
C. 30°
d. 40°
Answer:
36° .⠀
Explanation :
⠀
For a regular polygon of n sides, we have
[tex]\bf \longrightarrow \qquad Each \: exterior \: angle = { \bigg( {\dfrac{360}{n} } \bigg)}^{ \circ} [/tex]
⠀
Here, We are to find the measure of each exterior ange of a regular decagon.
⠀
So, we know a regular decagon has 10 sides, so n = 10 .⠀
Now, substituting the value :
⠀
[tex]\sf \longrightarrow \qquad Each \: exterior \: angle_{(Decagon)} = { \bigg( {\dfrac{360}{10} } \bigg)}^{ \circ} [/tex]
⠀
[tex]\sf \longrightarrow \qquad Each \: exterior \: angle _{(Decagon)}= { \bigg( {\dfrac{36 \cancel0}{1 \cancel0} } \bigg)}^{ \circ} [/tex]
⠀
[tex]\sf \longrightarrow \qquad Each \: exterior \: angle_{(Decagon)} = { \bigg( {\dfrac{36}{1} } \bigg)}^{ \circ} [/tex]
⠀
[tex] \pmb{\bf \longrightarrow \qquad Each \: exterior \: angle_{(Decagon)} = 36^{ \circ} }[/tex]
⠀
Therefore,
The measure of each exterior angle of a regular decagon is 36° .Answer:
It is 36 degrees because the out side is equal to 360 degrees
If you divide that by ten you get 36 for each angle

Nicole accepted a new job at a company with a contract guaranteeing annual raises. In the first year, Nicole's salary will be $100000 and after working for the company for 5 years, she will have a salary of $110000. Write an equation for S,S, in terms of n,n, representing Nicole's salary after working nn years for the company.
Answer:
S=2000n+100000
Step-by-step explanation:
Since Nicole will have a salary of $110000 after working 5 years for the company, we know that S = 110000 when n = 5.
Find the slope using the two points.
110000 - 100000 10000
m = ------------------------ = ---------- = 2000
5-0 2
The slope shows how much the salary increases each year, which is the same thing as saying that Nicole got a raise of $2000 every year.
