Answer:

a=22,\\b=31,\\c=13

Step-by-step explanation:

When choosing equations to write, make sure you choose a pair that allow you to isolate a variable and solve for it.

Sample solution:

a+25+28=16+25+34,\\\\a+28=16+34,\\a+28=50,\\a=\boxed{22}

16+b+28=16+25+34,\\b+44=75,\\b=\boxed{31}

34+c+28=16+25+34,\\c+28=41,\\c=\boxed{13}

As part of a research project on student debt at TWU, a researcher interviewed a sample of 35 students that were chosen at rando
Inga [223]

Answer:

Option a is right

Step-by-step explanation:

Given that as part of a research project on student debt at TWU, a researcher interviewed a sample of 35 students that were chosen at random concerning their monthly credit card balance.

Sample average = 2573

Variance = 4252

Sample size = 35

STd deviation of X = \sqrt{4252} \\=65.21

Score of student selected at random X=1700

Corresponding Z score = \frac{1700-2573}{65.201} \\=-13.38

Rounding of we get Z score = -13.4

option a is right

Convert into mixed number 81/3 and -29/2
LuckyWell [14K]
Hmmmm to convert from improper to mixed, simply do the division of both, the quotient gets upfront, the remainder as the numerator, for example,

how many times 3 goes into 81?  well, 27 times, with a remainder of 0, thus  \bf 27\frac{0}{3}

how many times does 2 go into 29?  well  14 times, with a remainder of 1, thus  \bf -14\frac{1}{2}

TRUE or FALSE: Every number raised to a negative exponent will have a value smaller than 1. Explain your reasoning.
Sveta_85 [38]

Answer:

<h3><u>Required Answer</u><u>:</u><u>-</u></h3>

Every number raised to a negative exponent will have a value smaller than 1.

  • This is False statement
<h3><u>Reason</u><u> </u><u>:</u><u>-</u></h3>
  • It will only be negative if the number is negative with an odd exponent.
  • what you're actually doing is dividing instead of multiplying.
<h3>For Example:-</h3>

\sf 4^2=16 \\ But \\ \sf 4^{-2}={\dfrac {1}{16}}

Whats 1 and 2/3 + 1 and 5/6​
Dima020 [189]
1 2/3 + 1 5/6

We’ll start by converting the 2/3 to 6ths so we have a common denominator.

Look at the denominator first. 3 x 2 is 6, so we need to multiply the numerator by 2 as well. 2/3 = 4/6.

So we have 1 4/6 + 1 5/6 = 2 9/6
But you know they’ll want you to reduce that so it’s 3 3/6...or 3 1/2.

Let me know where you have questions.
