In albany it is -4°f in chicago it is -14°f‚ in minneapolis it is -11°f‚ and in toronto it is -13°f. in which city is the coldest?

Answers

Answer 1
Chicago because on the number line, the numbers to the left get smaller, and the numbers to the right get bigger. Negatives on the number line are going right, and getting smaller, even though it seems the numbers are getting bigger.
EX: -14,-13, -12,-11,-10...
Answer 2

the largest negative number would be the coldest, so -14 would be the coldest.

 Chicago is the coldest city

The answer would be 8%. To do this, all I did was multiply each percentage by $4.50 to get the sales tax. After the multiplication, you can add your sales tax to $4.50. You can do this on each percentage until you match the final price, $4.86.

Here's my work for 8%:

Help me plz math (picture)

Answers

For 34, since each diameter is in scientific notation , meaning that we have one number (1-9) followed by a decimal, we simply see which has the smallest power, which is cell C.

For 35, we multiply them out to get 0.83*10^2 (we subtract exponents when dividing). Since scientific notation is one integer from 1-9 followed by a decimal, we move 0.83 one place to the right and therefore remove one power from 10^2, getting 8.3*10

Daniel Plays Videogames for 2/3 (Fraction) of an hour every night before dinner. hos many hours if videogames does he play altogether after 5 days.

Answers

What you should do here is either multiply the fractions, add them, or convert them into decimals and then add them. 

Multiplication: 2/3 (amount of hours he plays) x 5 (how many days he plays)
2/3 x 5/1 = 10/3   He plays a total of 10/3 hours after 5 days.

Addition: 2/3 + 2/3 + 2/3 + 2/3 + 2/3 = 10/3

Decimal: 2/3 is 0.6666666, we'll use 0.66 for short. 0.66 x 5 = 3.3
He plays a total of 3.3 hours after 5 days

5^2-11 over 6(3). Evaluate the expression. A. 7. B. 2/9. C.-1/63. D. 7/9

Answers

The first thing you do is exponents, so you get (25-11)/6(3). After that simplify the denominator to 18. So, you get (25-11)/18. When you subtract the numerator you get 14/18. This reduces to 7/9.

So the answer is D, 7/9.

There will be 1020 students in the school doing household chores for at least two hours every week.

What is a ratio?

A ratio is a comparison of two attributes of a similar kind.

Based on the random sample, the number of students doing household chores for at least two hours every week =64+3+1 =68

Out of 100, the number of students doing household chores for at least two hours every week = 68

So, out of 1, the number of students doing household chores for at least two hours every week = 68/100

So, out of 1500, the number of students doing household chores for at least two hours every week = (68/100)*1500 =1020

Thus, there will be 1020 students in the school doing household chores for at least two hours every week.

Maryann is testing the effectiveness of a new acne medication. There are 100 people with acne in the study. Fifty-five patients received the acne medication, and 45 other patients did not receive treatment. Thirty of the patients who received the medication reported clearer skin at the end of the study. Twenty-two of the patients who did not receive medication reported clearer skin at the end of the study. What is the probability that a patient chosen at random from this study took the medication, given that they reported clearer skin?

Answers

Answer: 58 %

Step-by-step explanation:

Let M represents the event of taking medicine, M' represents the event of not taking medicine and C represents the event of clearing skin,

Thus, according to the question,

n(M) = 55,

n(M') = 45,

n(M∩C) = 30,

n(M'∩C)= 22,

⇒ n(C) = n(M∩C) + n(M'∩C) = 30 + 22 = 52

Let S shows the total number of people,

⇒ n(S) = 100

Hence, the probability of cleared skin,

[tex]P(C)=\frac{n(C)}{n(S)}=\frac{52}{100}=0.52[/tex]

And, the probability of cleared skin of that people who took the medicines,

[tex]P(M\cap C)=\frac{n(M\cap C)}{n(S)}=\frac{30}{100}=0.3[/tex]

Thus, the probability that a patient chosen at random from this study took the medication, given that they reported clearer skin,

[tex]P(\frac{M}{C})=\frac{P(M\cap C)}{n(C)}=\frac{0.3}{0.52}=0.57692307692\approx 0.58 = 58\%[/tex]

Answer: 0.58

Step-by-step explanation:

Let A = Event that the patients received the acne medication.

B = Event that the patients did not receive the acne medication.

C = Patient reported  reported clearer skin.

Now,

[tex]P(A)=\dfrac{55}{100}=0.55\ \ ,P(B)=\dfrac{45}{100}=0.45[/tex]

[tex]P(C|A)=\dfrac{30}{55}\ \ , P(C|B)=\dfrac{22}{45}[/tex]

Using Bayes theorem, The probability that a patient chosen at random from this study took the medication, given that they reported clearer skin:

[tex]P(A|C)=\dfrac{P(A)\cdot P(C|A)}{P(A)\cdot P(C|A)+P(B)\cdot P(C|B)}\\\\=\dfrac{0.55\cdot\dfrac{30}{55}}{0.55\cdot\dfrac{30}{55}+0.45\cdot\dfrac{22}{45}}=0.576923076923\approx0.58[/tex]

Hence, the required probability : 0.58

The greatest common factor of a number n and 6 is 3. What are all of he possible whole-number values for n?

Answers

Answer:  Odd multiple of 3.

[tex]3,\ 9,\ 15,\ 21, \ 27, \ 33, \ 39,\ 45,...........[/tex]

Step-by-step explanation:

Given : The greatest common factor of a number n and 6 is 3.

Then, it is clear that n should be a multiple of 3.

Prime factorization of 6 :

[tex]6=2\times3[/tex]

So for n a even number then the greatest common factor will be 6.

Thus , the possible choice for n is a odd multiple of 3.

Hence, the possible whole-number values for n are :

[tex]3,\ 9,\ 15,\ 21, \ 27, \ 33, \ 39,\ 45,...........[/tex]

Alex spend 3/4 of his money. He gave 1/4 of the remainder to his sister. He had $120 left. How much did have in the beginning?

Answers

x = amount of money he had in the beginning

Because he spent 3/7, he has 4/7 left.

(4/7x)

We have to take 1/4 off THIS value. He has 3/4 of this value left.

(4/7x)1/4

Now, lets set it up as an equation

(4/7x)1/4 = 120

Multiply both sides by 4

4/7x = 480

Multiply both sides by 7/4

x = 480 * 7/4
x = 840
