The value of x is 26 degrees.
Explanation: If the whole line is 180 degrees, you would subtract 90+64 which is 154 and you would subtract that from 180 which is 26.

Answer:

$1\frac{9}{12}$

Step-by-step explanation:

Convert any whole numbers to improper fractions

$\frac{9}{4}-\frac{3}{6}$

Find the LCM of the denominators and use multiplication to change the denominators to the LCM

$\frac{27}{12}-\frac{6}{12}$

Subtract

$\frac{21}{12}$

Simplify

$1\frac{3}{4}$

$1\frac{9}{12}$ can be simplified to $1\frac{3}{4}$ so the answer is $1\frac{9}{12}$

The corner section of a football stadium has 6 seats on the first row. Each row after that has an additional 3 seats. How many s

julia-pushkina [17]

9514 1404 393

Answer:

Step-by-step explanation:

The number of seats in a row will give an arithmetic sequence:

6, 9, 12, 15, ...

The first term is 6; the common difference is 3. The general term is ...

an = a1 +d(n -1) . . . . . . n-th term of sequence with first term a1, difference d

The 20th term of the sequence is ...

a20 = 6 +3(20 -1) = 6 +57 = 63

There would be 63 seats on the 20th row.

A candy company claims that 25% of the candies in its bags are colored green. Steve buys 32 bags of 32 candies, randomly selects

Luden [163]

Answer:

45.88%

Step-by-step explanation:

We have in this case a binomial distribution when p = 0.25, since the probability is 25%

. The formula that we will use in excel is BINOM.DIST, separated by commas we must put the value of x, n, p and also if it is true or false. We know that n equals 32.

In this case we need to know when x = 7, 8 and 9 and add this, and thus we will obtain the probability:

P (X = 7) + P (X = 8) + P (X = 9)

Excel formulas: = BINOM.DIST (7,32,0.25, FALSE) + BINOM.DIST (8,32,0.25, FALSE) + BINOM.DIST (9,32,0.25, FALSE)

P = 0.1546 + 0.1610 + 0.1431

P = 0.4588

Probability that steve agrees with the company's claim 45.88%
