4 pounds of bananas cost $2.76. What was the cost per pound?

Answer:

8.12

Step-by-step explanation:

Hey There!

When you round to the nearest hundredth you are rounding the number 2 digits away from the decimal point which is 1

remember we base the rounding off of the number after 1 which is 6

5 or more raise the score

so 8.1165 rounded to the nearest hundredth would be

Answer:

- 43

Step-by-step explanation:

Expression: (3m+2n−6) and (−4−6m+7n)

n= -2 and m=5

Before inserting the values, let's add both expressions.

(3m+2n−6)  + (−4−6m+7n)

3m+2n−6   −4 − 6m + 7n

-3m + 9n - 10

Inserting the values;

-3(5) + 9(-2) - 10

-15 - 18 -10

Answer:

C

Step-by-step explanation:

Answer: C

Step-by-step explanation:

Reducing discretionary spending is one way to potentially increase one's savings. Thus, option C is correct.

The amount of money earned that is not used for immediate expenses is saved. It is money that is saved up and really not spent buying.

This disposable income, used in order to pay for all necessary and semi-products and services, comes from their discretionary income. A discretionary income is the sum of revenue we have left over after covering all of the ones living expenditures.

Discretionary revenue refers to the sum of money left over after all this has been met. Depending on the person's preferences, they can choose to spend it on products and services or save/invest it. Other necessary costs also occur.

Therefore, option C is the correct option.

[tex]cos(x)[/tex]

Step-by-step explanation:

Let's recall the definition of the trigonometric identities in place:

[tex]cot(x)=\frac{1}{tan(x)} =\frac{cos(x)}{sin(x)}[/tex]  and

[tex]csc(x)=\frac{1}{sin(x)}[/tex]

Then, we substitute and simplify as follows:

[tex]\frac{cot(x)}{csc(x)}=cot(x)*\frac{1}{csc(x)}=\frac{cos(x)}{sin(x)}*sin(x)=cos(x)[/tex]

Answer:

Equation of parabola:  8*(y - 2) = (x - 3)^2

or

y = (1/8)*(x - 3)^2 + 2

Step-by-step explanation:

focus at (3,4) and its directrix y = 0.

Focus equation:  (h, k + c) = (3, 4)

Directrix equation  y =  k - c = 0

so  h = 3,   k + c = 4,   k - c = 0

Solve  the system :  k + c = 4 and k - c = 0

add the equations together:     k + c + k - c = 4 + 0

2k = 4

k = 2

so   k + c = 4,    2 + c = 4,   c = 2

4c (y - k) = (x -  h)^2

4*2 *(y - 2) = (x - 3)^2

8*(y - 2) = (x - 3)^2

Answer:

4√2/7

Step-by-step explanation:

Suppose cos(x)=-1/3, where pi/2≤x≤ pi

tan(2x) = sin(2x)/cos(2x)

Since sin2x = 2sinx cosx

cos 2x = 2cos²x-1

Substitute

tan(2x) = 2sinx cosx/ 2cos²x-1

Given cosx = -1/3

adjacent = -1

hyp = 3

opp = √3²-(-1)²

opp = √9-1

opp = √8

sinx = opp/hyp

sinx = √8/3

tan(2x) = 2sinx cosx/ 2cos²x-1

tan(2x) = 2(√8/3)(-1/3)/ 2(-1/3)²-1

tan2x= (-2√8/9 )÷ (2/9 - 1)

tan2x = -4√2/9 * 9/-7

tan 2x = 4√2/7

Answer:

h0:u ≥ 21.1

h1: u < 21.1

t statistics = -2.632

pvalu = 0.007

there is sufficient evidence to support claim

Step-by-step explanation:

null hypothesis

h0 = u≥21.1

alternative = u < 21.1

to get test statistics

barx - u / s/√n

= 19.4 - 21.1 / 3.23/√25

= -2.632

we calculate for the p value given this test statistics and the degree of freedom = 25-1 = 24

lest tailed p value = 0.0073 this is approximately 0.007

p value is less than the level of significance so we reject h0

we conclude that we have enough evidence to support h1, mean tar conent is less than 21.1

Answer:

£32 and £32

Step-by-step explanation:

The computation of the amount that should be left and equally distributed is shown below:

The cost of hotel for one night is £84

Brenda has make a deposit of £20

So, the remaining amount left is

= £84 - £20

= £64

Now this amount should be equally distributed between them i.e. £32 and £32

Answer:

Answer:

1. False.

II. False.

III. True.

Step-by-step explanation:

In Statistics, sampling can be defined as a process used to collect or select data (objects, observations, or individuals) from a larger statistical population using specific procedures.

There are various types of sampling used by researchers and these are;

a. Random sampling.

b. Systematic sampling.

c. Stratified sampling.

d. Cluster sampling.

e. Opportunity or convenience sampling.

1. False: Using a systematic sample guarantees that members of each group within a population will be sampled. It is a stratified sample that does.

A systematic sampling is a type of probability sampling method which involves the researcher selecting or collecting data from a larger population.

Under systematic sampling method, samples are selected from an ordered (fixed) sample population at periodic interval.

2. False: Using a cluster sample guarantees that members of each group within a population will be sampled. It is a stratified sample that does.

3. True: Using a stratified sample guarantees that members of each group within a population will be sampled.

In Statistics, Stratified random sampling can be defined as a method of sampling that involves dividing a population into smaller groups known as strata.

In stratified random sampling, the strata are formed based on member's shared characteristics (e.g female or male, occupation, education) or attribute (e.g black or white).
