What is the answer??????

dexar [7]

Answer:

38 5/28

Step-by-step explanation:

Well start with the whole numbers 24 and 13 This is adding so that means everything has to be added together. 13+24=37 Now, lets go the fractions.

Find the LCD (Least Common Denominator) of 3/4 and 3/7 and rewrite to solve with the equivalent fractions. (remember the Denominator is the BOTTOM PART of the Fraction. Such as the 4 in 3/4.)

LCD = 28

21/28 + 12/28 = 33/28 which can be simplified to 1 5/28. Combining the whole and fraction parts 37 + 1 + 5/28 = 38 5/28 And that will be your answer. Another way you can do this is

converting mixed numbers to fractions Meaning put them in improper form where the numerator (the top number of a fraction is bigger than the denominator such as 4/3) , our initial equation becomes, 99/4 + 94/7

Applying the fractions formula for addition,

(99×7) + (94×4) / 4×7

= 693+376 / 28 =

= 1069/ 28

Simplifying 1069/28, the answer is

= 38 5/28

And one more thing. An easier way to make a mixed number a improper fraction is the multiply the denominator by the whole number then add the numerator and whatever the denominator is it stays for example

38 5/28.

28 times 38 = 1064 then add the 5 and you get 1069! But we aren't done yet, the denominator was 28 so that means the full answer is 1069/28 and that is the Improper fraction form!

Hope this helps! (sorry I took so long)

A)4x-3=2x+7 B)2x+6=7x-14 (Need working out otherwise it proves it as wrong Ty x)

Anna71 [15]

Answer:

A) x = 5

B) x = 4

Step-by-step explanation:

A) First, we add -2x to both sides and also add 3 to both sides. Then we divide everything by 2. (steps as shown below)

$4x -3 = 2x +7\\2x = 10\\x = 5$

B) First, we add -2x to both sides and also add 14 to both sides. Then we divided everything by 5. (steps as shown below)

$2x + 6 = 7x - 14\\20 = 5x\\4 = x$

(hope you found the steps helpful!)

Suppose that a particular candidate for public office is in fact favored by 48% of all registered voters in the district. a poll

Nutka1998 [239]

Given that a particular candidate for public office is in fact favored by 48% of all registered voters in the district, thus p = 0.48

If a polling organization will take a random sample of 550 voters, i.e. n= 550.

The approximate probability that p̂ will be greater than 0.5 is given by:

$P(\hat{p}\ \textgreater \ 0.5)=1-P(\hat{p}\leq0.5) \\ \\ =1-P\left(z\leq \frac{0.5-0.48}{\sqrt{ \frac{0.48(1-0.48)}{550} }} \right) \\ \\ =1-P\left(z\leq \frac{0.02}{\sqrt{ \frac{0.2496}{550} }} \right)=1-P\left(z\leq \frac{0.02}{0.0213} \right) \\ \\ =1-P(z\leq0.9388)=1-0.82609=0.1739$

Therefore, the approximate probability that p̂ will be greater than 0.5, causing the polling organization to incorrectly predict the result of the upcoming election is 0.1739.
