what is the difference between the LCM and the hcf of 24,36 and 40 ​

Answers

Answer 1

Answer:HELLO!

Step-by-step explanation:

Hii friend,

Prime factorisation of 24 = 2 × 2 × 3 × 2

Prime factorisation of 36 = 2×2 × 3 × 3

Prime factorisation of 40 = 2 × 2 × 2× 5

HCF of 24 , 36 and 40 = 2 × 2 = 4

LCM of 24 , 36 and 40 = 2 × 2 ×2 × 3 × 3 × 5 = 360

A department store is having a clothing sale. If a $35.00 pair of pants has a discount tag of 20% off, what is the sale price?

Answers

Answer:

$28.00

Step-by-step explanation:

You start with 35.00.

Now 10% of this is 3.5.

Multiply by 2 because it's 20%.

You get 7, so 7 is 20% of 35.00.

35.00 minus 7 is 28.00.

The pair of pants will be 28.00 dollars!

Identify the constant of Proportionality Write an equation to relate weight, w, to the price, p.

Answers

Answer:

m = .45

p = .45w

______

.45 = 9/20

Explanation:

m is the rate of change equal to the price over the weight or p/w.

Because this relationship is proportional, each weight divided by its corresponding price must equal the same fraction because it is constant.

We can prove this by dividing each price by its weight to find this proportion.

1.35/3 = 2.7/6 = 27/60 = 9/20 = 0.45

1.71/3.8 = 171/380 = 9/20 = 0.45

2.34/5.2 = 234/520 = 117/260 = 9/20 = 0.45.

Since equal the same value, this means that 9/20 or .45 is our proportion.

in terms of p = mw

p/w = 9/20.

p = mw → p/w = m → m = p/w = .45 .

Thus, p = .45w,

so m = .45.

Which means that for every .45 or 9/20 w or weight, there is a price of $1.

Consider the following problem: There are 722 identical plastic chips numbered 1 through 722 in a box. What is the probability of reaching into the box and randomly drawing the chip numbered 552

Answers

Answer:

Probability of reaching Chip number 552 = 1 / 722

Step-by-step explanation:

Given:

Total number of chips = 722

Chip number selected = 552

Computation:

Probability of reaching Chip number 552 = Number of chip selected / Total number of chips

Probability of reaching Chip number 552 = 1 / 722

A patient needs a total dose of 50 grams of albumin. The pharmacy has 50 m
bottles of 25% Albumin in stock. How many bottles should the pharmacy
technician prepare to provide the required dose?

Answers

Answer : The number of bottles should the pharmacy  technician prepare to provide the required dose are 4 bottles.

Step-by-step explanation :

As we are given that a patient needs a total dose of 50 grams of albumin and the pharmacy has 50 mL bottles of 25% Albumin in stock.

Now we have to determine the number of bottles should the pharmacy  technician prepare to provide the required dose.

As,

The pharmacy  has stock albumin = [tex]50mL\times \frac{25}{100}[/tex]

The pharmacy  has stock albumin = 12.5 mL

So,

Number of bottles should the pharmacy  technician prepare to provide the required dose = [tex]\frac{50}{12.5}[/tex]

Number of bottles should the pharmacy  technician prepare to provide the required dose = 4

Therefore, the number of bottles should the pharmacy  technician prepare to provide the required dose are 4 bottles.

A researcher is interested in consumer preferences among three brands of yogurt. A sample of 90 people is obtained,

and each individual is asked to taste each brand and then select his/her favorite. The resulting frequency data are as

follows:

Brand A

Brand B Brand C

37

21

32

Do the data indicate any significant preferences among the three brands? Test at the .05 level of significance.

State the null hypothesis (1 point), the expected frequency for each category (3 points), the value of chi-

square (4 points), the df (1 points), the critical value of chi-square (2 points), and the decision regarding

significance (1 points).

Answers

Answer:

Step-by-step explanation:

From the given information:

The null hypothesis: all three brands are equally likely to their expected value

The alternative hypothesis: preferences exist among the three brands i.e. at least one is different from the expected value.

The expected frequency = [tex]f_e[/tex]  

The observed frequency = [tex]f_o[/tex]

[tex]f_e[/tex]                    [tex]f_o[/tex]                      [tex](f_o- f_e)^2[/tex]                       [tex]\dfrac{(f_o - f_e)^2}{f_e}[/tex]

37                   30                       49.00                        1.633

21                    30                        81.00                        2.700

32                   30                         4.00                         0.133

                                                                [tex]X^2 = \sum\dfrac{(f_o-f_e)^2}{f_e} = 4.47[/tex]

Degree of freedom = [tex](n-1)[/tex]

= 3 -1

= 2

At ∝ = 0.05 and df = 2

The critical value [tex]X^2_{0.05, 2}= 5.99[/tex]

Decision rule:

Since the calculated chi-square is less than the critical value, we do not reject the null hypothesis.

Thus, the null is retained with a calculated chi-square value of 4.47 and a critical chi-square value of 5.99.
