Step-by-step explanation:

[tex]6 - 3a = 21 \\ - 3a = 21 - 6 \\ - 3a = 15 \\ \frac{ - 3a}{ - 3} = \frac{15}{ - 3} \\ a = - 5[/tex]

Hope this helps you.

Can I have the brainliest please?

Answer:

a = -5

Step-by-step explanation:

When you're solving a question like this, your aim is to get the unknown (in this case 'a') by itself on one side of the equation. You do this by adding/subtracting/multiplying/dividing, whatever is necessary for the question. Note that if you do something to one side of the equation, you must do the same to the other.

6-3a=21

First let's get rid of the 6: subtract 6 from both sides.

6-6-3a=21-6

-3a=15

Now let's get rid of the -3: divide both sides by -3.

-3a=15

-3a/-3 = 15/-3

a= -5

A bag of skittles contains 18 yellow, 12 green, 20 red, 10 orange, and 14 purple
skittles. If one skittle is drawn at random, what is the

P( purple | color name with six letters )

Answers

Answer:   D) 1/3

===========================================================

Explanation:

The vertical bar is a shorthand way of saying "Given".

Writing P(A | B) means "probability of A given B"

In this case, we are given that "color name with six letters", so we are 100% certain that whatever was picked has six letters in the color name. That rules out green (5 letters) and red (3 letters). We'll ignore these colors entirely.

Instead we focus on yellow, orange, and purple.

Add up the frequencies for these colors to get: 18 yellow + 10 orange + 14 purple = 42 total

Of that total, there are 14 purple, so....

14/42 = (1*14)/(3*14) = 1/3

represents the probability we're after.

There's a 1 in 3 chance of getting a purple skittle if we are told, or we know 100%, that whatever color we picked has 6 letters in the name.

Side note: 1/3 = 0.333 = 33.3% approximately.

1/3 for people who don’t want to read all of that

find the accumulated value when $1000.00 is invested for 5 years at 6% annual interest rate compounded quarterly ​

Answers

Answer:

The amount is $1346.86 and the interest is $346.86.

Step-by-step explanation:

To start, use the formula A = P(1+[tex]\frac{r}{n}[/tex])ⁿ°ᵇ [In this case b = time in years]

So, P =  $1000, r = 6$, n = 4 and B = 5 years

After plugging it in you get,

                                                  A = 1000(1+[tex]\frac{.06}{4}[/tex])⁴°⁵

                                                  A = 1000 x 1.015^20

                                                  A = 1000 x 1.346855

                                                  A = 1346.86

To find the interest, use the formula A= P + I; Since A = 1346.86 and P = 1000 you get:

                                                  1346.86 = 1000 + I

                                                  I = 1346.86 - 1000

                                                  I = 346.86

Then you're finished! Hope this helped!

Antibiotics in Infancy
Exercise 2.19 describes a Canadian longitudinal study that examines whether giving antibiotics in infancy increases the likelihood that the child will be overweight later in life. The study included 616 children and found that 438 of the children had received antibiotics during the first year of life. Test to see if this provides evidence that more than 70% of Canadian children receive antibiotics during the first year of life.
(a) State the null and alternative hypotheses
(b) Calculate the z-statistic.
(c) Find the p-value.
(d) Make a generic conclusion about the null hypothesis, using α = 0.05
(e) Make a conclusion in context.

Answers

Answer:

e)The information from the sample does not give enough information  to support that more than 70% of Canadian children receive antibiotics during the first year of life

Step-by-step explanation:

The proportion we will use for the test is  p  = 70 %

From a random sample we got

n  =  616

x = 438      then   p₁ = 438/616     p₁  =  0,71    p₁  = 71 %

Then  q₁  =  1 - p₁      q₁  = 1 - 0,71    q₁ = 0,29   q₁ = 29 %

a) Hypothesis test:

Null hypothesis                      H₀           p₁   = p

Alternative hypothesis          Hₐ           p₁  > p >70 %

CI = 95 % significance level    α  = 5 %   α = 0,05

z(c) for  α  =  0,05   from z-table is    z(c)  = 1,64

b) To calculate  z(s)  =  ( p₁  -  p ) / √ p₁*q₁ / n

z(s) = ( 0,71  -  0,70 )/ √ 0,71*0,29/616

z(s) = 0,01 /0,01828

z(s) = 0,547 ≈ 0,55

c) p-value for   z(s) is from z-table   p-value ≈ 0,7088

d) p-value > 0,05   then we accept H₀  we don´t have enough evidence to reject H₀

e)The information from the sample does not give enough information  to support that more than 70% of Canadian children receive antibiotics during the first year of life

I like healthy foods that have a high percentage of my daily vitamins. I bought a bag of apples. There are still six apples left That's 75% of the apples. How many apples did I have to begin with?​

Answers

Answer:

8 apples to begin with.

Step-by-step explanation:

First, we know that 75% is 3/4 of 100%

If 3/4 = 6 apples then we need to divide each side by three to get 1/4.

So 1/4 = 2

Now, we multiply each side by 4 to get 4/4

So 4/4(100%) = 8

8 apples is the answer
