£350 in the ratio 2:3

Answer:

Step-by-step explanation:

Sample standard deviation refers to the statistical metric that is used to measure the extent by which a random variable diverges from the mean of the sample and it is calculated by adding the squares of the deviation of each variable from the mean, then divide the result by a number of variables minus and then computing the square root in excel of the result.

Hope this helps :}

Pls mark brainliest :P

And have an amazing day <3

Answer:

A sample standard deviation is a statistic. This means that it is calculated from only some of the individuals in a population. Since the sample standard deviation depends upon the sample, it has greater variability. Thus the standard deviation of the sample is greater than that of the population.

Using the combination formula, it is found that the committee can be selected in 1,211,760 ways.

Combination formula:

[tex]C_{n,x}[/tex] is the number of different combinations of x objects from a set of n elements, given by:

[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]

In this problem:

They are independent, so we can just multiply them, thus:

Answer:

The square root of 144 is 12

Step-by-step explanation:

[tex]\sqrt{144} = 12[/tex]

because 12 x 12 = 144

it's basically 12 doubled... [tex]12^{2}[/tex]

Answer:

12 is the square root of 144.

Step-by-step explanation:

That means if you multiply 12 by 12, you will get 144.

That's called 12² (12 squared)

The square root is the opposite of that. √144=12.

Keep in mind that 12*12=144.

Answer:

B

Step-by-step explanation:

28+25+29+18 = 100

red = 25

25/100     =    1/4

The required empirical probability is 1/4 which gets the color of red P(R).

The probability is defined as the possibility of an event being equal to the ratio of the number of favorable outcomes and the total number of outcomes.

A spinner has 4 equal sectors colored yellow, blue, green, and red. If in 100 spins we get

28 blue (B), 25 red (R), 29 green (G), and 18 yellow (Y) outcomes

To find the empirical probability of getting a red outcome, we need to divide the number of red outcomes by the total number of spins:

P(R) = 25 red outcomes / 100 spins

Apply the division operation, and we get

P(R) = 1/4

Hence, the required empirical probability is 1/4

Therefore, the correct answer is 1/4 or option B.

Answer:

a. Elsa's total change of her stocks is $448.

b. The change of the club's size each week was -5 members.

Step-by-step explanation:

a. The value of one share increased by 8 dollars. Elsa has 56 shares of that certain stock.

Given the information above, multiply [tex]56[/tex] × [tex]8[/tex] to find the total change in her stocks.

[tex]56[/tex] × [tex]8=448[/tex]

b. 30 members left a club on 6 weeks.

Given the information, divide [tex]-30[/tex] ÷ [tex]6[/tex] to find the amount of members leaving the club per week.

Answer:

If you mean could x be eight, then yes, x could equal eight. However, any number could be the solution as this equation has an infinite solution.

Step-by-step explanation:

Once again, I am going off of you are asking if eight could be x. If that is what you are asking, here is the reason.

The equal sign shows that both sides equal each other. If you plug in 8 for x, then you get:

8+6=8+6

14=14

Does 14=14? Yes, so plugging in eight for x works. However, looking at this, we can see that your solution would actually be an infinite solution. This is because, no matter what number we plug in for x, we will get a true statement.

After being compounded for a period of 5 years, the amount will rise to $5,200.82.

The interest is given on an annual basis and so is the period yet the compounding period is quarterly. The first thing to do therefore, is to convert the interest and period to quarterly measures.

Interest = 8% / 4 = 2% per quarter

Periods = 5 x 4 = 20 quarters

Amount will be $3,500

The amount after 5 years will be:

= Amount x ( 1 + rate) ^ number of periods

= 3,500 x ( 1 + 2%) ²⁰

= $5,200.8158859

= $5,200.82

In conclusion, the amount will be $5,200.82 after 5 years.

Answer: $2,187.50

Step-by-step explanation:

Define all the exemptions that applie:

exemption for being married:  $3000

exemption for 1 dependent:     $ 1,500

3000 + 1500 = 4500

Subtract the exemptions from the yearly earnings:

67000 - 4500 = 62,500

Now, applied the 3.5 % tax

3.5 / 100 = (0.035)

62,500 x 0.035 = 2187.50

Answer: 4 carrots and 6 ears of corns

Step-by-step explanation:

Howard needs 4 carrots and 6 ears of corn for 12 servings of stew.

To get how many carrots and ears of corn Howard needs for 12 servings of stew, we can set up a proportion based on the number of servings.

Let x be the number of carrots

Let y be the number of ears of corn needed for 12 servings.

Proportion:

6 servings of stew need 2 carrots and 3 ears of corn

12 servings of stew need x carrots and y ears of corn

(2 carrots) / (6 servings) = (x carrots) / (12 servings)

(3 ears of corn) / (6 servings) = (y ears of corn) / (12 servings)

2 * 12 = 6 * x

3 * 12 = 6 * y

24 = 6x

36 = 6y

Solve for x and y:

x = 24 / 6

x = 4

y = 36 / 6

y = 6.
