Girl i-
1. 3 shorts
$11 * 5 shirts = $55
$82-$55= $27
$27 left you divide by 9 because that’s how much each shorts were and you get 3 shorts

2. so for the special she buys 6 right
which means you could just add another $15
because half of 6 is 3 and with those 3 you pay $15 for the special and so just add another which means you’d pay $30 bucks for 6 of them. and normally without the deal she’d pay $54 because you times $9 with 6 lotions. and so now you subtract $54-$30= $24. meaning you saved $24.

3. so if she spent $18 just group them. first you start of with $3 and get 10 cards now you do 6 more groups because 3 times 6 = 18 and now when you group them you have 6 groups with 10 cards and times those 2 you get 60 cards.

4. $17 each month
$2 times 8 = 16 bucks add the 17 she has to pay each month and you get $33.

5. 4 plots with 5 fruits trees in each meaning you have 20 trees in total.
so now add to each tree 3 fruits and take away 17 of them and in 1 plot you have 15 fruits and from the second plot you take away 2 more fruits so at last you only have like 13 fruits of the second plot and 2 more plots that are complete and in each plot there are 15 fruits
now add 15 fruits (for one plot) and another 15 (for the other) which equals 30 fruits
and you still have 13 and add 30 you get 43 fruits left.

sorry that’s all i could do for you rn
but i hope it helped! have a great day:)

I need to explain/show work.<br> Help please
Fittoniya [83]

Answer:

adult tickets = 17, children tickets = 9

Step-by-step explanation:

Let x be the number of children and y the number of adults

Then given that 26 tickets are sold, we can write

x + y = 26 → (1)

Given that ticket cost was $194 we can write

5.5x + 8.5y = 194 → (2)

Rearrange (1) expressing y in terms of x by subtracting x from both sides

y = 26 - x → (3)

Substitute y = 26 - x into (2)

5.5x + 8.5(26 - x) = 194 ← distribute and simplify left side

5.5x + 221 - 8.5x = 194

- 3x + 221 = 194 ( subtract 221 from both sides )

- 3x = - 27 ( divide both sides by - 3 )

x = 9

Substitute x = 9 into (3) for corresponding value of y

y = 26 - 9 = 17

Hence number of adult tickets sold = 17

number of children tickets sold = 9

Answer:

The unusual X values ​​for this model are: X = 0, 1, 2, 7, 8

Step-by-step explanation:

A binomial random variable X represents the number of successes obtained in a repetition of n Bernoulli-type trials with probability of success p. In this particular case, n = 8, and p = 0.53, therefore, the model is {8 \choose x} (0.53) ^ {x} (0.47)^{(8-x)}. So, you have:

P (X = 0) = {8 \choose 0} (0.53) ^ {0} (0.47) ^ {8} = 0.0024

P (X = 1) = {8 \choose 1} (0.53) ^ {1} (0.47) ^ {7} = 0.0215

P (X = 2) = {8 \choose 2} (0.53)^2 (0.47)^6 = 0.0848

P (X = 3) = {8 \choose 3} (0.53) ^ {3} (0.47)^5 = 0.1912

P (X = 4) = {8 \choose 4} (0.53) ^ {4} (0.47)^4} = 0.2695

P (X = 5) = {8 \choose 5} (0.53) ^ {5} (0.47)^3 = 0.2431

P (X = 6) = {8 \choose 6} (0.53) ^ {6} (0.47)^2 = 0.1371

P (X = 7) = {8 \choose 7} (0.53) ^ {7} (0.47)^ {1} = 0.0442

P (X = 8) = {8 \choose 8} (0.53)^{8} (0.47)^{0} = 0.0062

The unusual X values ​​for this model are: X = 0, 1, 7, 8

A crayon has a mass of 30 grams. How many crayons can be made with 30 kilograms of colored wax
PolarNik [594]
The conversion factor between kilo and base unit which is grams in this question is 1000 so there is 1000 grams in 1 kilogram so first we need to convert kilograms to grams so we multiply by 1000 so 30kgx1000= 30000 grams so to find the number of crayons then we divide by 30 which is the mass of one crayon to find out how many we need so 30000/30= 1000 so you would need 1000 crayons
