Consider a large population with a mean of 100 and a standard deviation of 21. A random sample of size 36 is taken from this population. The standard error of the sampling distribution of sample mean.

Answers

Answer:

3.5

Step-by-step explanation:

Given that:

Population mean (m) = 100

Standard deviation (σ) = 21

Sample size (n) = 36

The standard error of the sampling distribution of sample mean :

Standard Error is given by:

Standard deviation / sqrt(n)

Thus,

Standard Error = 21 / sqrt(36)

Standard Error = 21 / 6

Standard Error = 3.5

if ∠PQR ≅ ∠STU, then ∠STU ≅ ∠PQR

We conclude that  'Symmetric Property of Angle Congruence' illustrates this statement.

Step-by-step explanation:

We know that the Symmetric Property of Angle Congruence can be defined as

For any angles X and Y, if ∠X≅∠Y , then ∠Y≅∠X

For example, Let suppose

m∠X = 20m∠Y = 20

As ∠X≅∠Y i.e. 20 ≅ 20

then

∠Y≅∠X i.e. 20 ≅ 20

Given

if ∠PQR ≅ ∠STU, then ∠STU ≅ ∠PQR

Thus, we conclude from the above discussion that 'Symmetric Property of Angle Congruence' illustrates this statement.

a school population of 1200 increases by 6% per year what will the population be after 4 years

Answers

Answer:

Step-by-step explanation:

1200x6%(.06)=72

72x4=288

1200+288=1488

1200+72=1272+72=1344+72=1416+72=1488

You can use many methods, I like to use the multiplier method for these questions. 6% = 0.06. Because it increase you add it to 1, if it decreased you’d subtract from 1. So 1200 x 1.06^ 4 (to the power of 4). 1514.972352. But because you can’t half a decimal of a person you’d round it to the next whole number so 1515.

Holly begins with 1 penny in her piggy bank. She adds 2 pennies on day 1, 4 pennies on day 2, and 8 pennies on day 3. She continues this pattern for 30 days.

a Each amount of pennies corresponds to a unique day in this sequence.
b The graph of this sequence would pass the horizontal line test.
c Each day corresponds to a unique amount of pennies in this sequence.
d The graph of this sequence would pass the vertical line test.

Answers

Answer:

The answer is c and b

Step-by-step explanation:

I took the test

Options B, C and D are correct.

The Graph of this sequence would pass the horizontal line test.Each day corresponds to a unique amount of pennies in this   sequence.The Graph of this sequence would pass the vertical line test.

We have Holly and her penny collection.

We have to select the correct alternatives from the given.

Starting from 1 marble if you add 'x' marble every day for n days, then you have a total of 40 marbles. Find n.

1 + nx = 40

nx = 39

n = 39/x

According to the question-

Initial Amount in piggy bank = 1 penny.

Now -

She adds -

2 Pennies on Day 1.

4 Pennies on Day 2.

8 Pennies on Day 3.

Therefore, the following sequence represents her collection -

1, 2, 4, 8 .....

It can be seen that each day corresponds to a unique amount of pennies in this sequence.

Now -

Vertical line test → to satisfy this test the graph should not have two or more points going through a vertical line.

Horizontal Line test → to clear this test the graph should not have two or more points going through a Horizontal line.

If we plot the graph of this function - Refer to image attached. It can be seen that the graph of this sequence passes horizontal line and vertical line test.

Hence, Options B, C and D are correct.

Problem 1: Bob’s Citrus and Nursery sells cartons of citrus fruits. There are 24 oranges in each carton. They have 5,643 oranges to pack into cartons. How many cartons can they fill?

Problem 2: This year, 4,338 grapefruits have been harvested so far. Bob’s has 18 storage bins for grapefruits. If the grapefruits are distributed evenly among 18 bins, how many grapefruits are in each bin?
248 per bin.

Answers

The number of cartons that the oranges would fill in  Bob’s Citrus and Nursery would be 235 cartons.

The number of grapefruits in each bin would be 241 grapefruits per bin.

How to find the number of cartons ?

To find the number of cartons of oranges that would be filled, use the number of oranges that go into carton in Bob’s Citrus and Nursery and the number of oranges they have to pack. The formula would be:

= Number of oranges / Number of oranges per carton

= 5, 643 / 24

= 235 cartons

How to fin the number of grapefruits per bin ?

The same logic is applied to find the number of grapefruits that would be in each bin. If each bin would have an equal number of grapefruits, the number of grapefruits per bin would be:

= Number of grapefruits / Number of bins

= 4, 338 / 18

= 241 grapefruits per bin

Mary bought 6 bracelets that cost the same amount and one necklace which cost $86. The items she bought totaled $254 before sales tax was added. What was the cost of each bracelet?
A) $14
B) $56
C) $42
D) $28

Answers

1 necklace will therefore cost 34/4 = $8.5

Step-by-step explanation:

She spent between $39 and $59. let us find the average of the amount she spent = 39+59 / 2 = $49.

At an average, she spent $49.

The price of a bracelet is $5 and each bracelet costs the same amount and she bought 3 bracelets = $5 x 3 bracelets each = $15... She spent $15 on the bracelets.

Thus $49 - $15 = amount spent on the 4 necklaces = $34.

4 necklaces cost $34, 1 necklace will therefore cost 34/4 = $8.5

the number of terms of the series is [tex]\frac{805-5}{4}+1=201[/tex]

the series have:
