The terms are 4y, 5, and 3y. The like terms are 4y and 3y. The coefficients are 4 and 3. The only constant is 5.

explanation:

The coefficients are the numbers that come with the letters. For example, in (4y), the coefficient is 4. It says that y is being multiplied by 4.

The terms are each coefficient-letter pair. For example, 4y is a term. If there is no coefficient on a letter, the coefficient is actually 1.

Like terms are any two terms that have the same letter. So, 4y and 3y are like terms.

Constants are the numbers that stand alone.

note: the letters are actually called variables.

Find how X and y compare when log X = 6.6 and log y = 3.6

asambeis [7]

Answer

x = 3981071.7055

y = 3981.0717

x > y

Step by step explanation

First let's find the value of x and y by taking anti - log.

log X = 6.6

X = log^ -1 (6.6)

X = 3981071.7055

Similarly,

log Y = 3.6

Y = log ^(-1) 3.6

Y = 3981.0717

Once we found the values of X and Y , we can easily compare them.

Here x > y

Hope you will understand the concept.

Thank you. :)

You want to obtain a sample to estimate a population proportion. At this point in time, you have no reasonable estimate for the

Vedmedyk [2.9K]

Answer:

416025

Step-by-step explanation:

For confidence interval of 99%, the range is (0.005, 0.995). Using a z-table, the z-score for 0.995 is 2.58.

Margin of error = 0.2% = 0.002.

Proportion is unknown. So, worse case proportion is 50%. p = 50% = 0.5.

\\ $n = \left(\frac{\texttt{z-score}}{\texttt{margin of error}} \right )^2\cdot p\cdot (1-p) \\ = \left(\frac{2.58}{0.002} \right )^2\cdot 0.5\cdot (1-0.5)=416025$

So, sample size required is 416025.

If the sales tax in Maple Town is 9.5%, how much would an ice cream of $4.25 cost with the tax added? Please explain.

faltersainse [42]

To find the sales tax, you need to find 9.5% of 4.25

4.25*.095 = <span>.40375

Now we need to add the sales tax to the price.

4.25 + </span>.40375 = <span>4.65375
Because dollars one have 2 decimal points we should round this to 4.65

Hope this helped!
