Write words to match the expression 3 + (4 × 12)

Answer:

9

Step-by-step explanation:

1. To find how 3x+10=16, we must subtract 10 from both sides.

                           -10  -10

2. now we have 3x=6, we divide 3 from both sides

                           3    3

3. we end with x=2.

Now we know x=2, we plug in 2 into our second equation.

1. 4(2)+1 we multiply 4 times 2.

2. we are then left with 8+1, which equals 9.

Answer:

When solving a multi step equation, you use PEMDAS (parentheses, exponents, multiplication, division, add, subtract), and you also use PEMDAS when solving a multi step inequality. However, inequalities are tricky in the fact that if you multiply or divide by a negative number, you must flip the sign. And while normally there are 1 or 2 solutions to a multi step equation, in the form of x= #, you'll have the same thing, but with an inequality sign (or signs).

A two-step equation is an algebraic equation that takes you two steps to solve. You've solved the equation when you get the variable by itself, with no numbers in front of it, on one side of the equal sign.

Step-by-step explanation:

1

The population is the total sample from which part of the event is considered. It's like in a set, the population would encompass everything as a whole. From the statement given, we're expected to find the population. The population is B.

All NBA players since 1966. This is because it is from this pool that the draft picks were selected, and narrowed down to 45% which were centre backs.

2

The specified attribute is A.

Being a No. 1 draft pick, because that's the fulcrum of the statement in itself

3

B sample proportion. The population like I stated above, is all NBA players since 1966, thus, a population proportion would have had the statement like this.

45% of all NBA players since 1966...

So, therefore, it's a sample proportion since it is referring to the draft pick, and not the NBA players

​

x= 8−2− −12 = 4−1−i 3

​ =−0.2500−0.4330i

x= 8−2+ −12 = 4−1+i 3

Answer:

7.8y - 26.2

Step-by-step explanation:

Answer:

y=-0.15

Step-by-step explanation:

Subtract the 6.4y on the left by the 14.2y, you will get 7.8y. The reason why you subtract instead of add is because you always do the opposite when adding/subtracting from the other side of the equal sign. Next, add the 12.5 to the -13.7 so you get -1.2. The whole equation would be 7.8y=-1.2. Then divide by 7.8 on both sides so that you get y=-0.15. Hope this helps :)

The answer is you can fit 18 books on the bookshelf. :)

You can fit 18 books perfectly.

We have a bookshelf of given dimensions.

We have to determine how many books can fit in this shelf.

There are 12 inches in 1 feet.

According to the question, we have -

Length of bookshelf = [tex]$3\frac{1}{2}[/tex] feet  = [tex]$\frac{7}{2}[/tex] feet = [tex]$\frac{7}{2} \times 12[/tex] inches = 42 inches.

Width of each book - [tex]$2\frac{1}{4}[/tex] inches = [tex]$\frac{9}{4}[/tex] inches.

Assume that the total number of books that can fit in a bookshelf is x. Therefore -

x = [tex]$\frac{42}{\frac{9}{4} } =42\times \frac{4}{9}[/tex]

x = 18.66 = 18 books (Approx.)

Hence, you can fit 18 books perfectly.

Answer:

x=3

Step-by-step explanation:

2x+5=11

first subtract 5 from 11

2x=6

then divide 6 by 2

x=3

Hello.

Subtract 5 from both sides of the equation.

2x + 5 (-5) = 11 (-5)

Simplify

2x = 6

Divide both sides of the equation by 2.

2x (/2) = 6 (/2)

x = 3

The unknown number in the equation is 3.

50 kg sacks of rice for $59.00.

Step-by-step explanation:

Lets do the math. First, I want to see how much 50 kg of of the first option costs.

$15.45 is worth 10kg.

$15.45*3=$46.35

Since the fourth on is free, the sum will stay the same.

$46.35+$15.45=$61.80.

50 kg of the first option is worth $61.80.

50 kg of the second option is worth $59.00.

$61.80 > $59.00.

So, the second option is cheaper and the better deal.

Answer:

Yes it is

Step-by-step explanation:

Pi is measured to be around 3.14 and 4.6 is of course bigger than 3.14 so yes it is

answer:

yes

explanation:

pi is 3.14 (and those numbers going on forever) even though pi looks big, the numbers are behind the decimal which is very small.

sorry I'm bad at explaining but I just went over this in class

4 is bigger than 3 so automatically 4.6 is bigger than pi

Answer:

28/21 = 3x - 7/x+11

x = 13

Step-by-step explanation:

The value of x from the given diagram is 13. Option A is correct.

From the given similar triangles;

Cross multiply

28(21) = (3x-11)(x+11)

(3x-11)(x+11) = 588

Expand

3x^2 + 33x - 11x - 121 = 588

3x^2+22x- 709 =0

On factorizing, the value of x is 13

Step-by-step explanation:

Confidence interval = 90% = 0.90.

1 - 0.90 = 0.10

Mean of 15 batch:

724+718+776+760+745+759+795+756+742+740+761+749+739+747+742 = 11253/15

= 750.2

Mean of second batch:

735+775+729+755+783+760+738+780

= 6055/8

= 756.875

Sd = 20

Z-alpha/2 = 1.64

= (750.2-756.875)-1.64*√20²/15 + 20²/8

= -21.0348

(750.2-756.875)+1.64*√20²/15 + 20²/8

= 7.68

2. The upper limit of the interval is less than 10 so in conclusion the difference in mean batch viscosity is about 10 or less than 10

Step-by-step explanation:

Answer:

The answer is below

Step-by-step explanation:

Let S denote syntax errors and L denote logic errors.

Given that P(S) = 36% = 0.36, P(L) = 47% = 0.47, P(S ∪ L) = 56% = 0.56

a) The probability a program contains both error types = P(S ∩ L)

The probability that the programs contains only syntax error = P(S ∩ L') = P(S ∪ L)  - P(L) = 56% - 47% = 9%

The probability that the programs contains only logic error = P(S' ∩ L) = P(S ∪ L)  - P(S) = 56% - 36% = 20%

P(S ∩ L) = P(S ∪ L) - [P(S ∩ L') + P(S' ∩ L)] =56% - (9% + 20%) = 56% - 29% = 27%

b) Probability a program contains neither error type= P(S ∪ L)' = 1 - P(S ∪ L) = 1 - 0.56 = 0.44

c)  The probability a program has logic errors, but not syntax errors =   P(S' ∩ L) = P(S ∪ L)  - P(S) = 56% - 36% = 20%

d) The probability a program either has no syntax errors or has no logic errors = P(S ∪ L)' = 1 - P(S ∪ L) = 1 - 0.56 = 0.44

Answer:

Kindly check explanation

Step-by-step explanation:

Given the following :

Programs with syntax errors ; n(S) = 36%

Programs with logic errors; n(L) = 47%

Programs with atleast one of the two errors = 56%

P(S) = 0.36 ; p(L) = 0.47

P(SnL) = x

P(S) only + p(L) only + p(SnL) = 0.56

P(S) only = 0.36 - x

P(L) only = 0.47 - x

P(SnL) = 0.36 - x + 0.47 - x + x = 0.56

0.83 - x = 0.56

x = 0.27

B) probability that program contains neither error :

1 - p(program contains atleast one of the two errors)

1 - 0.56 = 0.44

C) probability of logic error but no syntax error :

P(L) - p(SnL)

= 0.47 - 0.27

= 0.20

First notice that θ is in quadrant I, where the sine and tangent will also be positive.

Then draw the angle in quadrant I. Drop a perpendicular to the x axis.

Since cosθ= 7/25, label the horizontal leg 7, and the hypotenuse 25; the vertical leg will be 24 by Pythagorean theorem.

Then sinθ=vertical/hypotenuse=  24/25 and tanθ= vertical/horizontal=  24/7

Step-by-step explanation:

The sum of the measures of the angles in a triangle is 180°. The equation relating angles 1, 2, 3 will reflect this fact.

  m∠1 +m∠2 +m∠3 = 180°

__

Of course, angle 3 is supplementary to angle 4, so we have ...

  m∠3 +m∠4 = 180°

Substituting this expression for 180° in the first equation, we have ...

  m∠1 +m∠2 +m∠3 = m∠3 +m∠4

Subtracting ∠3 from both sides, we are left with an equation relating angles 1, 2 and 4.

  m∠1 +m∠2 = m∠4

__

The "rule" expressing this last relationship is, "an exterior angle is equal to the sum of the remote interior angles." Knowing this relation can make a number of problems easier to solve.
