Order of Operations
emmasim [6.3K]

Given:

4 + 9 + 16 \div 4 - 8 -3 \times  5

To find:

The number of possible solutions, if the Order of Operations did not exist.

Solution:

We have,

4 + 9 + 16 \div 4 - 8 -3 \times  5

Now,

Case 1:

[4 + 9 + 16] \div [4 - 8 -(3 \times  5)]=29\div (4 - 8 -15)

4 + 9 + 16 \div  4 - 8 -(3 \times  5)=-\dfrac{29}{19}

Case 2:

[4 + 9 + 16] \div  (4 - 8 -3) \times  5=29\div  (-7\times 5)

4 + 9 + 16 \div  (4 - 8 -3) \times  5=-\dfrac{29}{35}

Case 3:

4 + 9 + (16 \div 4) - 8 -(3 \times  5)=4+9+4-8-15

4 + 9 + (16 \div 4) - 8 -(3 \times  5)=-6

Many more possibilities are there.

Therefore, there are more than 3 possible solutions.

AB is the angle bisector of ∠CAD. Solve for x.
Sliva [168]

Answer: x=7

Step-by-step explanation:

Since AB is a bisector, it cuts the angle in half, and since we know that the angle is a right angle, we know it’s 90 degrees, so knowing that you use the equation 7x-4= 45 (since 45 is half of 90), add 4 to both sides so you have 7x=49, the divide 49 by 7 and you get 7, so x= 7

25 points!<br> Find the value of X.
aleksklad [387]

\qquad\qquad\huge\underline{{\sf Answer}}

In the Triangle BCD, Angle B is 90° since tangent and radius are perpendicular to one another.

Now, let's find Angle C using Angle sum property of a triangle.

\qquad \tt \dashrightarrow \:\angle C + \angle B + \angle D = 180

\qquad \tt \dashrightarrow \:\angle C + 90 + 45= 180

\qquad \tt \dashrightarrow \:\angle C + 135= 180

\qquad \tt \dashrightarrow \:\angle C= 180 - 135

\qquad \tt \dashrightarrow \:\angle C= 45 \degree

Now, we know that Angle made by an arc on the centre is twice the Angle made by same arc on boundary of circle, hence we can infer that :

\qquad \tt \dashrightarrow \:2\angle C  = 10x

\qquad \tt \dashrightarrow \:10x = 2 \times 45

\qquad \tt \dashrightarrow \:x = 90 \div 10

\qquad \tt \dashrightarrow \:x = 9

So, the required value of x is 9

A sample of 32 people yielded the information about their health insurance in the given table.Two people who provided informatio
DochEvi [55]

From the table given

17 people have managed care plan

9 have Traditional insurance

6 have no insurance

The probability of an event happening is given as the ratio of the number of the possible outcome divided by the total outcome.

If two balls are taken, the probability that at least one has traditional insurance

TN or TM or TT or NT or MT

where T is for traditional insurance

N is for no insurance

M is for managed insurance

the probability that at least one of two people picked without replacement has traditional insurance

= 9/32 * 6/31 + 9/32 * 17/31 + 9/32 * 8/31 + 6/32 * 9/31 + 17/32 * 9/31

= (54 + 153 + 72 + 54 + 153)/992

= 486/992

= 243/496
