Please help fast! Rosa's friend Jake claims that he can read minds. To test Jake's abilities, Rosa chooses 3 different numbers
from 1 to 10. Rosa then asks Jake to identify which 3 of the 10 numbers she chose in the correct order.
Assume that Jake has no special abilities and is randomly guessing the numbers.

Answers

Answer 1

Jake's guesses are illustrations of probabilities.

The probability that Jake's guesses are correct is 1/720

The sample size is:

[tex]\mathbf{n = 10}[/tex] --- 10 different numbers

The probability that Jake's guesses are correct is as follows:

1st guess = 1/102nd guess = 1/93rd guess = 1/8

So, the required probability is:

[tex]\mathbf{Pr = \frac{1}{10} \times \frac 19 \times \frac 18}[/tex]

[tex]\mathbf{Pr = \frac{1}{720} }[/tex]

Hence, the probability that Jake's guesses are correct is 1/720

Answer for 33 = 1, 3, 11, 33.

This is because all of those numbers divide into 33 evenly / are factors of 33.

Answer for 93 = 1, 3, 31, 93

This is because all of those numbers divide into 93 evenly / are factors of 93.

Answer:

1) composite: 1, 3 , 11 , 33

2) composite 1, 3, 31, 93

Step-by-step explanation:

1) We know that 33 is divisible by 3 because the whole value is equal to 6, and the last digit is a 3.

2) We know that 93 is divisible by 3 because the last digit was 3, and all of the place values added up to 12, which is also divisible by 3.

A store sells bandanas for $2 each and combs for $1. Shelby buys 3 bandanas and a comb. Kendra buys 2 bandanas and 4 combs. Lucy has a "buy one get one half off" coupon, she plans on buying 4 bandanas. Find the total amount spent.

Answers

Answer:

6+1= 7

kendra:

2 bandanas, 4 combs

2×2 + 4×1

4×2=

since she has a buy 1 get 1 half off coupon

she pays full price for 2 hence 2×2= 4

half price for 2 hence 2×1 = 2

thus 4+2=6

total price= 7+8+6

Answers

Answer:

subtract 20 from both sides

Step-by-step explanation:

1. To find the answer, let's actually try solving the equation first and find the 2nd step.

2. (Solving)

Step 1: Distribute 2 to each term.

[tex](2)(x)+(2)(10)=60[/tex] [tex]2x + 20 = 60[/tex]

Step 2: Subtract 20 from both sides.

[tex]2x + 20 - 20 = 60 - 20[/tex] [tex]2x = 40[/tex]

3. Since we got that the second step was "subtract 20 from both sides," the answer is subtract 20 from both sides.

1) a supermarket sells articles during the festival seasons with a 10% discount. find the new price of the following articles.

i) A CFL bulb if the marked price is Rs. 280

ii) A bunion if the marked price is Rs. 650.

iii) A gas cooker if the marked price is Rs. 7500

Answers

Answer:

252, 585, 6750

Step-by-step explanation:

We have to think that the regular price represents 100% and we need 10 of 10% to make an 100%. So if we divide the regular price by 10 will get our 10%.

i) A CFL bulb if the marked price is Rs. 280

10 % of 280 is 280/10 = 28

discounted price is 280 -28 = 252

ii) A bunion if the marked price is Rs. 650.

10 % of 650 is 650/10 = 65

discounted price is 650 -65 = 585

iii) A gas cooker if the marked price is Rs. 7500

10 % of 7500 is 7500/10 = 750

discounted price is 7500 -750 = 6750

Answers

Queremos saber cuantas porciones de arroz se preparan dado que conocemos cuantos gramos de arroz se utilizan.

Se prepararon 68 porciones.

Lo que sabemos en principio es que, por cada porción de arroz, se necesitan 70 gramos de arroz.

Sabemos que en total se utilizan 4,760 gramos de arroz. Para saber cuantas porciones se prepararon, hay que tomar el cociente entre la cantidad total utilizada y lo que se usa para cada porción.

Esto nos da:

4,760g/70g = 68

Es decir, se prepararon 68 porciones.
