Jill's weight is 92 kg 250 g. Jill's sister's weight is 8 kg 600 g less than Jill's weight. How much does the sister weigh?

Answers

Answer:

S = 83 g and 650 kg.

Step-by-step explanation:

Gram (g)= 1000 kilograms (kg).

Jill (J)= 92000 + 250 kg.

J = 92250 kg

Sister (S) = J - (8000 + 600 kg)

S = 92250 - 8600 kg

S = 83650 kg.

S = 83 g and 650 kg.

answer for 1a: 0.40, which is 40 cents.

what you need to do is you need to divide the amount of money of the drink which is £3.20, by the quantity of the drink which is 8, since £3.20 is the total amount of money for 8 cans.
£3.20 divided by 8 is 0.4, which logically would mean in your question it calculates to 40 cents.
another proof that the answer is 40 cents is when you multiply 0.40 by 8, it calculates to 3.2, which would mean in your question it calculates to £3.20 in total.
the answer to 1a is 40 cents.


answer for 1b: 0.35, which is 35 cents.
same thing as the first question, you need to divide the total amount of money of the drink which is £5.25, by the quantity of the drink which is 15, to calculate the actual price of the drink.
5.25 divided by 15 calculates to 0.35.
as said, the proof that the answer is right is if you multiply 0.35 by 15, it will calculate to 5.25.
the answer to 1b is 35 cents.

answer for 1c: the best value is shop A, because we have worked out that shop A sells the drink for 40 cents, and shop B sells the drink for 35 cents. therefore, shop A gets 5c more profit than shop B.

find (5.3x10^3)-(8x10^2)

Answers

(5.3 * 10³) - (8 * 10²)

= (5.3 * 10³) - (0.8 * 10³)

= 4.5 * 10³

Answer:

[tex](5.3 \times {10}^{3} ) - (8 \times {10}^{2} ) \\ = (5.3 \times {10}^{3} ) - (0.8 \times {10}^{3} ) \\ = (5.3 - 0.8) \times {10}^{3} \\ = 4.5 \times {10}^{3} \\ = \boxed{4500}[/tex]

introduces a study where researchers studying the relationship between honesty, age, and self-control conducted an experiment on 1G0 children between the ages of 5 and 15. The researchers asked each child to toss a fair coin in private and to record the outcome (white or black) on a paper sheet, and said they would only reward children who report white. Half the students were explicitly told not to cheat and the others were not given any explicit instructions. Differences were observed in the cheating rates in the instruction and no instruction groups, as well as some differences across children's characteristics within each group. (a) Identify the population of interest and the sample in this study. (b) Comment on whether or not the results of the study can be generalized to the population, and if the findings of the study can be used to establish causal relationships.

Answers

Answer:

The solution to this question can be defined as follows:

Step-by-step explanation:

In choice a:

Both children between 5 and 15 years old and 160 years old are also the populations of interest, and Kids from 5 to 15 years of age.

In choice b:

These findings could be compared like we do not know whether the groups were randomly selected, and the allocation is still not random; there could be no casual conclusion because the statement is valid even With sample research, and after randomization, filtering, and testing of 160 specimens (instruction vs no-instruction) Its analysis can be common to the community and replicated. There could be explanatory relations generated by experimental research. This analysis is observational and can therefore be used Causal relationships are established.gggg

Approximate: log5 ^4/7

Answers

Answer:

log5 (4/7)= log5 (4)- log5 (7)=-0.347708839

Step-by-step explanation:

for the first question which would be Approximate: log5 4/7 the answer would be B. –0.3477

and for the second question which would be Approximate: log1/2 5 the answer would be C.–2.3219

 

Answer: Option B ( -0.3477 )

Step-by-step explanation:   Using Properties of Logs

logb(x/y) = logbx - logby.

Furthermore

log5 (4/7)= log5 (4)- log5 (7)

Solve log 5 (4) and log 5 (7)  with the base change of the logarithm

log 5 4 = log 4 / log 5

Use the calculator (DESMOS):  log 5 4 =0.8613531161

log 5 7 = log 7 / log 5

log 5 7 =1.2090619551

Therefore, The answer is, log5 (4/7)= log5 (4)- log5 (7)=-0.347708839

For the second part of the question just to not make this too long the answer to the second part is: C ( -2.3219 )

Step-by-step explanation:

4 2/5+k=−3 2/11

Need help

Answers

Answer:

2/11

Step-by-step explanation:

Here we have two mixed numbers. Be very careful when handeling negative mixed numbers. Don't coonfuse "-3 2/11" with "-3 + 2/11"

4 2/5 + k = -3 2/11

I add a minus into the mixed fraction on the right. Of course you don't have to write an entire new line when you do calculations on paper.

4 2/5 + k = -3 -2/11

k = - 3 - 4 - 2/5 - 2/11

k= - 7 -2/5 -2/11

Make common denominators. Both 11 and 5 is prime numbers (numbers that are only divisible by one and itself). Therefore the common denominator is 5*11=55.

k= - (7*55)/55 - (2*11)/(5/11) - (2*5)/(11*5)

k = - 385/55 - 22/55 -10/55

k = - (385 +22+10)/55

k = - 417/55

Since 417 isn't divisible by neither 11 nor 5, this fraction is in it's simplest form.

btw correct me if i am wrong

Answer:

[tex] k = - 1 \frac{12}{55} [/tex]

Step-by-step explanation:

[tex]4 \frac{2}{5} + k = 3 \frac{2}{11} \\ \frac{22}{5} + k = \frac{35}{11} \\ k = \frac{35}{11} - \frac{22}{5} \\ k = \frac{175 - 242}{55} \\ k = \frac{ - 67}{55} \\ k = - 1 \frac{12}{55} [/tex]
