Answer:

4

Step-by-step explanation:

<u>Convert the mixed fraction into decimal form using a calculator</u>

\rightarrow 3\dfrac{175}{349} = 3.501 \ \ \ \ \ \text{(Upto three dp)}

Since the number in decimal form is about 0.002 more than 3.49, the number will round up to 4 (Nearest whole number).

Answer: ≈ 4.

Step-by-step explanation: In order to solve this, you need to turn this into an addition problem.  In order to do that, we need to transform the 3 into a fraction:

3/1 + 175/349.

Solve:

3/1 + 175/349 = 3.50143266 or ≈ 4.

Have a great day! :)

Which graph represents this system of equations?<br> y + 2x = 3<br> y + 2 = 3x
andrezito [222]

Answer:

The options are not given, so i will answer in a general way.

First, we have the system:

y + 2*x = 3

y + 2 = 3*x

To graph this system, the easier way is writing both equations as linear equations, like:

y = -2*x + 3

y = 3*x - 2

Now we just need to graph these two lines in the same coordinate axis.

To do it, we can replace the value of x by two different values in each equation, and see the correspondent value of y for these values. Then graph the two points, and draw a line that connects them.

For example, for the first equation if we have x = 0, we have:

y = -2*0 + 3

y = 3

Then we have the point (0, 3)

and if x = 1

y = -2*1 + 3 = 1

y = 1

we have the point (1, 1)

Now we only need to graph these points, and draw a line that passes through them.

Once we did this for both lines, the graph we will get will look something like the one above.

And the point where the lines intersect is the solution of the system of equations.

Which is the point (1, 1)

What is the approximate circumference of a circle that has a diameter of 25 yards? Round your answer to one decimal place. C = a
suter [353]

For this case we have by definition, that the circumference of a circle is given by the following formula:

C = \pi * d

Where:

d: Is the diameter of the circumference

So:

C = \pi * 25\\C = 78.5398

Rounding to a decimal we have:

C = 78.5 \ yards

ANswer:

C = 78.5 \ yards

Find the value of y A.y= 2 B.y= 4 square root 3 /3 C.y=4 D.y= 4 square root 3
jolli1 [7]

Answer:

The correct answer is option B.  4√3/3

Step-by-step explanation:

<u>Points to remember</u>

If a right angled triangle with with angles 30°, 60° and 90° then the sides are in the ratio 1 :√3 : 2

<u>To find the value of y</u>

From the figure we can see two right angled triangle.

From the figure we get height 'h' of large triangle is written by,

h : base : 8 = 1 : √3 : 2

Therefore h = 8/2 = 4

Also we can write,

y : h : hypotenuse of small triangle = 1 : √3 : 2

y : 4 : hypotenuse = 1 : √3 : 2

Therefore y = 4/√3 = 4√3/3

The correct answer is option B.  4√3/3

In a study of pleas and prison​ sentences, it is found that 6060​% of the subjects studied were sent to prison. Among those sent
Dovator [93]

Answer:

a. 40 %

b. 34.3 % ( approx )

Step-by-step explanation:

Let S is the event of the subjects studied that were sent to prison,

S' is the event of the subjects studied that won't sent to prison,

G is the event of pleading guilty,

G' is the event of not pleading guilty,

According to the question,

P(S) = 60% = 0.6 ⇒ P(S') = 1 - P(S) = 1 - 0.6 = 0.4,

P(S∩G) = 46% of 60% = 0.46 × 0.60 = 0.276,

P(S'∩G) = 36% of 40% = 0.36 × 0.40 = 0.144,

P(G) = P(S∩G) + P(S'∩G) = 0.276 + 0.144 = 0.42

a. The of getting someone who was not sent to prison, P(S') = 0.4,

b. the probability that this person was not sent to prison when it is given that the subject entered a guilty​ plea,

P(\frac{S'}{G})=\frac{P(S'\cap G)}{P(G)}=\frac{0.144}{0.42}\approx 0.343=34.3\%
