Using measurement concepts, it is found that the correct option is given by:

C) the area of a floor in an office.

------------------------------------------

  • Perimeter is measured in units.
  • Area is measured in units squared.
  • Volume is measured in cubic units.
  • Thus, square yards is a measure of area, which removes options A and D.
  • Additionally, yards are used to measure large dimensions, for example, the length and the width of an american football field. A restaurant table is not very large, being usually measured in centimetres or metres, while an office floor is large, thus, option C is correct.

Step-by-step explanation:

<u>Step 1: Define</u>

<em>Identify</em>

2(4 + 2x) ≥ 5x + 5

<u>Step 2: Solve for </u><em><u>x</u></em>

  1. [Distributive Property] Distribute 2:                                                                 8 + 4x ≥ 5x + 5
  2. [Subtraction Property of Equality] Subtract 5x on both sides:                       8 - x ≥ 5
  3. [Subtraction Property of Equality] Subtract 8 on both sides:                        -x ≥ -3
  4. [Division Property of Equality] Divide -1 on both sides:                                 x ≤ 3

Erica had 6 coins in her coin collection. She goes to a coin show and buys some more coins. How many coins does she have now?
goldfiish [28.3K]

Answer:

6+x with x equalling the amount of coins bought if that is what you were looking for

Step-by-step explanation:

if you want to make and equation out of this you don't know the amount of coins she bought so you use a variable (x) to replace that unknown number then since it says she bought more she is adding more to her collection which means it would be an addition problem, leaving you with 6+x for your final answer

A candy company claims that its jelly bean mix contains 15% blue jelly beans. Suppose that the candies are packaged at random in
I am Lyosha [343]

Answer:

Doubtful.

Step-by-step explanation:

Our values are,

P=0.15 \rightarrow 15\%Jelly Bean Mix.

The sample for us is n=200

And our proportion (x) is 40 .

We can calculate  with this dates the sample proportion and make he test statistic.

p=\frac{x}{n} = \frac{40}{200} = 0.20

H_0:P=0.15

H_1:P \neq 0.15

We use the formula for Test statistic, that is given by,

z= \frac{p-P}{\sqrt{\frac{P-(1-P)}{n}}}

z= \frac{0.20-0.15}{\sqrt{\frac{0.15(1-0.15)}{200}}}

z= 1.98

We see that our P-value: 0.048 (From the Table)

We note that p-value is less than 0.05, so we should to rejecyt the null hypothesis and conclude that the calim is doubtful
