A Mathematics paper consists of 12 questions of which not more than ten are to be answered. Given that the number of candidates who answer ten questions is equal to the number of candidates who answer nine questions only. Find the probability that a candidate chosen at random from among these two sets of candidates will have selected questions 1, 2 and 3 if all the questions have the same chance of being selected.

Answer:

angle DEF = 75 degrees

Step-by-step explanation:

angle DOF = 150 degrees, then arc DF also = 150 degrees

angle DEF = 1/2 arc DF = 75 degrees

1.) 1

Let's start with 18 degrees and then subtract 12 degrees from it

18-12=6

Now let's take 6 degrees and subtract 5 from it

6-5=1

At 2 pm the temperature was 1 degree.

2.) $125

Start with the total amount John had ($250) and then subtract his remaining amount ($125) to find out how much he withdrew.

$250-$125=$125

Answer:

Kerri should draw the two cities 4.2" or 4 1/5" apart.

Answer:

yellow : 8

Red : 4

Step-by-step explanation:

Yellow : Y and Red : R

R : Y = 12

They need to add up to 12 because its the total.

We know that yellow is twice the amount so

4×2= 8

so if yellow was to be times by 2 itd be 8 which will still add up to 12.

The number of yellow fish should be 8 and the number of redfish be 4.

Since Jacob has 12 fish, all of them are either yellow or red. There are twice as much yellow fish as red fish.

Here we assume the redfish be x

So, the yellow be 2x

So

2x + x = 12

3x = 12

x = 4

So, redfish should be 4

And, the yellow fish should be 8

Answer:

Your answers are C and D

Step-by-step explanation:

If you pay attention to the chart you will notice that medium duty fabric can last from 9000 to 15000 rubs meaning that since fabric B lasted 9200 it would be a medium duty fabric, making Fabric A light duty fabric.

A: This is INCORRECT because fabric B is medium duty

B: This is INCORRECT because Fabric B lasted longer than Fabric A

C: This is CORRECT because Fabric B is medium duty fabric

D:This is CORRECT because Fabric B lasted more rubs than Fabric A because its a more durable fabric

E: This is INCORRECT because Fabric A does not meet the requirements to be a Medium duty fabric.

Answer:

n = √3

m = √3

Step-by-step explanation:

The triangle is an isosceles right triangle with 2 equal base angles of 45° each.

Thus:

Reference angle = 45°

Hypotenuse = √6

Opposite = m

Adjacent = n

✔️To find m, apply the trigonometric function SOH, we have:

Sin 45 = opp/hyp

Sin 45 = m/√6

√6 × 1/√2 = m (sin 45 = 1/√2)

√6/√2 = m

√(6/2) = m

√3 = m

m = √3

✔️To find n, apply the trigonometric function, CAH:

Cos 45 = adj/hyp

Cos 45 = n/√6

√6 × √2/2 = n (cos 45 = √2/2)

√12/2 = n

√(4*3)/2 = n

(2√3)/2 = n

√3 = n

n = √3

Answer:

3c+12

Step-by-step explanation:

Are of rectangle = Length * Width

Given the following data

Length: (c+4) ft

Width: 3 ft

Area of the rectangle = 3 (c+4)

Expand

Area of the rectangle = 3(c) + 3(4)

Area of the rectangle = 3c  + 12

hence the expression in simplest form for the area of the rectangle is 3c+12

Answer:

V = 63°

U = 29°

X = 12°

Step-by-step explanation:

given that T = 88

88 = 7x+4

88 - 4 = 7x

84 = 7x

84 = 7*12

x=12

V = 60 + 3 = 63

U = 24 + 5 = 29

88 + 63 + 29

Check : 88 + 63 + 29 .= 180

Answer:

since the median means middle, you lay the numbers out from least to greatest.

Step-by-step explanation:

52, 72, 96, 21, 58, 40, 75 would go to

21, 40, 52, 58, 72, 75, 96.

then you cross out the numbers in a pattern so like

no more 21 and no more 96

no more 40, and no more 75

no more 52 and no more 72

this leaves you with 58!

Answer:

Step-by-step explanation:

The slope intercept form of a line is y=mx+b where m=slope and b=y intercept. So we should solve for y.

3x/5+25y=10, multiply all terms by 5 and the denominator cancels out

3x+125y=50, subtract 3x from each side

125y=-3x+50, divide both sides by 125

y=(-3+50)/125

slope=m=-3/125

y intercept=b=2/5

Step-by-step explanation:

Given:

The graph of a relation.

To find:

Whether the given relation in the graph is a function or not.

Solution:

First we need to understand the meaning of open circles and closed circles.

Open circle: It is a unfilled circle, it means, that value is not included in the solution set.

Close circle: It is a completely filled circle, it means, that value is included in the solution set.

A relation is a function if their exist a unique y-value (output value) for each x-value (input value).

The graph of a relation is a function, if the graph intersect each vertical line at most once. It is known as vertical line test.

For the vertical lines x=-1 and x=1, the graph has only one close circle and all other vertical line intersect the graph at most once.

Since the graph passes the vertical line test, therefore it represents a function.

Answer:

4 dozens.

Step-by-step explanation:

Since Ruby, Joey and Sully are baking cookies together, and they need 3/4 cup of flour and 1/3 cup of butter to make a dozen cookies, since Ruby brought 2 cups of flour and 1/4 cup of butter, Joey brought 1 cup of flour and 1/2 cup of butter, sully brought 1 1/4 cups of flour and 3/4 cup of butter, if the students have plenty of other ingredients that they need, to determine how many whole batches of a dozen cookies can they make the following calculation must be performed:

Flour: 2 + 1 + 1 1/4 = (4 1/4) / (3/4) = 4.25 / 0.75 = 5.666

Butter: 1/4 + 1/2 + 3/4 = (1 1/2) / (1/3) = 1.5 / 0.333 = 4.504

Thus, a maximum of 4 dozen cookies can be made.
