Sin (7pie/6)= ????????????

The value of the radical expression is A = -3n√12

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the equation be represented as A

Now , the value of A is

Substituting the values in the equation , we get

A = -√8n² ( 12 )

On simplifying , we get

A = -√108n²

Taking the value of n outside , we get

A = -n√108

On further simplification , we get

A = -n3√12

A = -3n√12

Hence , the value of the expression after simplification is A = -3n√12

Answer:  31 bacteria per square centimiter.

Step-by-step explanation:

The correct number of bacteria in the question is 2,450.

Hi, to answer this question we have to apply the next formula:

Area of a circle = π x (diameter/2) ^2

Replacing with the values given:

A = π x (10/2) ^2

A = π x (5) ^2

A = π x 25 = 78.54 cm2

Next, we have to divide the number of bacteria (2,450) by the area of the dish  

2450 / 78.54 = 31.19 = 31 bacteria per square centimiter.

Answer:

This data set contains three variables, one of which is categorical

Step-by-step explanation:

The three variables are: Gender, Length and Weight

A categorical variable is a variable that can take on one of a limited, and usually fixed, number of possible values. In this example, the only categorical variable is Gender, because it can only take two possible values, female (F) or male (M). The other two variables are not categorical because they have to be measured, and their values are not fixed.

Answer: I feel that the answer might be B. $825 because I did calculate it but I lost my calculations so the answer is B but I just don't have the reason why sorry

The maximum amount Ban can afford for a' mortgage each month when he makes $39,600 a year is $825. Option B is correct.

The mortgage is a type of loan which is taken to purchase the home or lands.

In the given problem, Ben makes $39,600 a year. The rate of interset for the mortgage he has is 4. Thus, the amount he can afford for a'mortgage each year is,

[tex]M=\dfrac{39600}{4}\\M=9900[/tex]

There is total 12 months in one year. Thus, the maximum amount he can afford for a'mortgage each month is,

[tex]M=\dfrac{9900}{12}\\M=825[/tex]

Thus, the maximum amount Ban can afford for a' mortgage each month when he makes $39,600 a year is $825. Option B is correct.

Answer:

Jason Inherit a land with a 45% chance of having oil.

Step-by-step explanation:

 The probability of the land having oil is = P ( O) = 45 /100

The probability of the land having oil is= Q(O ) =55/100

The machine has an accuracy of 80%. This suggests that 8 out of 10 times the machine will give a wrong reading.

The probability of the correct reading is=  P(M)=80/100

The probability of the incorrect reading is=Q(M)=20/100

The case when the machine predicts there is no oil and there is indeed oil can be calculated:Probability=Probability of oil present  ×  probability of the incorrect reading

Probability=P(O) x Q(M)

Probability=45/100 x 20/100

Probability=9/100

The probability of the test predicting no oil in land and the land has oil is  0.09 or 9%

Answer:

74 pages/hour

Step-by-step explanation:

The average rate of change is the difference in the numbers of pages  divided by the difference in the numbers of hours.

At the end of 3 hours, 90 pages were read.

At he end of 5 hours, 238 pages were read.

Difference in hours: 5 hours - 3 hours = 2 hours.

Difference in pages: 238 pages - 90 pages = 148 pages

The average rate of change is the difference in pages divided by the difference in hours.

average rate of change = (148 pages)/(2 hours) = 74 pages/hour

Answer:

45

Step-by-step explanation:

The two angles with measures are a linear pair and supplementary, so their measures add to 180 deg.

3x + x = 180

4x = 180

x = 45

____________________________________

Solution,

X°+3x°=180°( sum of angle in straight line)

or,4x°=180°

or,X=180/4

X=45

The right answer is 45

hope it helps

Good luck on your assignment
