PLEASE HELP, I A NOT SURE IF THIS IS THE RIGHT ANSWER

Total number of sports students = 65

Total number of music/drama students = 25

Total number of work students = 10

Total number of students = 65 + 25+ 10 = 100

Probability = Total number of favourable outcomes/Total number of outcomes

Probability of picking a sports student = 65/100 = 13/20

Therefore, probability of picking a sports student is 13/20

Actually Welcome to the concept of Surface Areas and Volume.

==> Volume of Cylinder = πr^2h

==> 27π = πr^2(3)

==> 27 = r^2 (3)

==> r^2 = 9

==> r = 3 inch

hence the radius is 3 inches.

Answer:

The approximate length of the two other sides is 10cm

Step-by-step explanation:

Given

[tex]Base\ Length = 18[/tex]

[tex]Height = 4[/tex]

Required

The length of the two other sides

Divide the triangle to 2 (See attachment)

Considering one of the triangles, we have:

[tex]l^2 = 4^2 + 9^2[/tex]

[tex]l^2 = 16 + 81[/tex]

[tex]l^2 = 97[/tex]

Take square roots

[tex]l = \sqrt{97[/tex]

[tex]l = 9.8488[/tex]

[tex]l = 10[/tex] --- approximated

Answer:

Range

Step-by-step explanation:

The range of a given set of data is the difference between the largest value and the smallest value in the data. For convenience and ease in the calculation, it is advisable to place the data in ascending order.

For example, given the following set of data:

4,9,5,6,2

To find the range;

=> First arrange the data in ascending order

2,4,5,6,9

=> Find the smallest and largest numbers and then find their difference.

Since the data has been arranged, it is obvious to see that the smallest number is 2 and the largest number is 9.

Therefore the;

range = 9 -2 = 7

Answer:

5x+4=-6

5x=-6-4

5x=-10

x=-10/5

x=-2

Step-by-step explanation:

Answer:

[tex] \sf \: x = - 2[/tex]

Step-by-step explanation:

Now we have to,

→ Find the required value of x.

The equation is,

→ 5x + 4 = -6

Then the value of x will be,

→ 5x + 4 = -6

→ 5x + 4 - 4 = -6 - 4

→ 5x + 0 = -10

→ 5x = -10

→ 5x ÷ 5 = -10 ÷ 5

→ [ x = -2 ]

Hence, the value of x is -2.

Answer:

1.54cm    2. 112m   3.  576cm    4. 52ft

Step-by-step explanation:

Answer:

5,5,7,8,10

Step-by-step explanation:

mode=5    so that would appear the most so start with 5,5

median=7  that would be the middle number so 7 would be next

when you add 5+5+7=17  now just choose any number to add to 17 and I choose 10 which makes 17+10=27.  

mean=7  so that means the total has to be divided by how many numbers you have, which is 5.  So the total divided by 5 should equal 7.  Since have 27, the number divided by 5 to get 7 is 35.  So, add to 27 to get 35 which would be 8.

27+8=35  that is your total.  Now divide by 5 to get the mean of 7.

Answer:

The total area is 594cm.²

Step-by-step explanation:

The top and bottom each have a length of 36 cm.

Blue side:

36/3= 12cm. (36/3 for the length of one side of a blue square)

12*12= 144cm.² (area of one blue square)

144*3= 432cm.² (area of all the blue squares)

Orange side:

36/8= 4.5cm. (the length of one side of an orange square)

4.5*4.5= 20.25cm.² (the area of one orange square)

20.25*8= 162cm.² (the area of all the orange squares)

Total area:

432+162= 594 cm.²

Answer:

2 1/3 hours or 2 hrs, 20 min

Step-by-step explanation:

1 5/6 + 1/2

make mixed number into improper fraction and change 1/2 to 3/6

11/6 + 3/6 = 25/6

14/6 equals 2 2/6 which simplifies to be 2 1/3 or 2 hrs, 20 min

Answer:

[tex]x=15.3[/tex]

Step-by-step explanation:

In right triangles only:

The sine of an angle is equal to its opposite side divided by the hypotenuse. (o/h)

The cosine of an angle is equal to its adjacent side divided by the hypotenuse. (a/h)

The tangent of an angle is equal to its opposite side divided by its adjacent side. (o/a)

Therefore, we have the following equation:

[tex]\sin 58^{\circ}=\frac{x}{18},\\x=18\sin 58^{\circ}\approx \boxed{15.3}[/tex]

Alternative:

[tex]\cos 32^{\circ}=\frac{x}{18},\\x=18\cos32^{\circ}\approx \boxed{15.3}[/tex]

Answer:

38°

Step-by-step explanation:

The measure of angle NPM is 38°.

➠ ∠MPJ + ∠LPM = 180°

➠ ∠MPJ + 90° = 180°

➠ ∠MPJ = 180° – 90°

➠ ∠MPJ = 90°

∠NPM = ∠MPJ – ∠JPN

➠ ∠NPM = 90° – 52°

➠ ∠NPM = 38°

Answer:

-42

Step-by-step explanation:

Which expression is equivalent to 14 x minus 21 over 7 ?

Mathematically this expression is written as:

= (14 × -21)÷ 7

= (14 × -21)/7

= - 294/7

= -42

Therefore, the equivalent of the above expression is calculated as -42

Answer:

(6, 3)

Step-by-step explanation:

Note that the opposite side of parallelogram are congruent, hence;

Jk = LM

2y + 3 = 5y - 6

2y - 5y  =-6 - 3

-3y = -9

y = 9/3

y = 3

Similarly;

KL = JM

8x – 10 = 3x+20

8x - 3x =  20 + 10

5x = 30

x = 30/5

x = 6

Hence (x,y) is (6, 3)
