1/3 * 420 = amount of t-shirts sold in the morning

1/3 * 420 = 420/3 = 140 t-shirts

140 t-shirts were sold, so remaining is 420 - 140

420 - 140 = 280 remaining t-shirts

4/7 * 280 = amount of t-shirts sold in the afternoon

4/7 * 280 = (280/7) * 4 = 40 * 4 = 160 t-shirts

160 t-shirts were sold, so remaining is 280 - 160

the remaining t-shirts = 120 t-shirts

120 t-shirts are left to sell at the end of the day

The measure of one side of the square lies between 13 and 14.

A square is a quadrilateral with four equal sides that has four angles that are equal and two diagonals that bisect each other at 90 degree.

Area of a square = length of a side²

length of a side = √ area

Answer:

C) 20.97 AED

Step-by-step explanation:

To find the expected value, E(X), or mean μ of a discrete random variable X, simply multiply each value of the random variable by its probability and add the products. The formula is given as [tex]\displaystyle E(X)=\mu=\sum xP(x)[/tex].

Here, x represents values of the random variable X, [tex]P(x)[/tex] represents the corresponding probability, and symbol [tex]\displaystyle \sum[/tex] represents the sum of all products [tex]xP(x)[/tex]. Here we use the symbol [tex]\mu[/tex] for the mean because it is a parameter. It represents the mean of a population.

In this case, the expected value of the ticket is [tex]\displaystyle E(X)=\mu=\sum xP(x)=12(0.08)+18(0.15)+20(0.31)+22(0.08)+24(0.15)+25(0.23)=20.97[/tex]

This means that Ahmad can expect to win 20.97 AED for the ticket.

Step-by-step explanation:

c is the cost so it should be equal to and 60 a month so 60m and +35

Answer:

C

Step-by-step explanation:

6X - (15 + 4X) = 35

6(25) - (15 + 4(25)) = 35

150 - (15 + 100) = 35

150 - (115) = 35

35 = 35 (True)

The volume of the cylinder will be equal to V=1885 cubic cm.

The Volume of the cone is the amount of quantity, which is obtained in the 3-dimensional space. The cylinder is the right circular object with some height like bamboo, bottles, rods etc all are cylinders.

The formula for calculating the volume of the cylinder is given as:-

V=πr²H

Here we have the radius of the cylinder r= 10 cm and the height of the cylinder is H=6 cm

V=  π x (10)² x  6

V=1885 cubic cm.

Hence the volume of the cylinder will be equal to V=1885 cubic cm.

Answer:

Step-by-step explanation:

Remark

When a quadrilateral is inscribed in a circle, the opposite angles are supplementary. x is opposite 112 degrees. Therefore x and 112 add up to 180 degrees.

Formula

x + 112 = 180                      Subtract 112 from both sides.

Solution

x + 112-112 = 180 - 112

x = 68

Answer

x = 68

Answer:

Step-by-step explanation:

#9.

x° = 200° and x = 200

y° = 100° and y = 100

Step-by-step explanation:

FIFO means "first in - first out". so, it is airways the oldest in the inventory that is sold. that means the newest or youngest items in the inventory remain.

the end inventory shows 70 units.

that means, all the November units (64) plus 6 of June are still there.

a.

the cost of the ending inventory is

576 + 6×8 = 576 + 48 = $624

b.

the cost of goods sold is then

1727 - 624 = $1,103

control :

196 + 483 + (59-6)×8 = 679 + 53×8 = 679 + 424 =

= $1,103

correct.

From the calculation, we can see that, the  probability that an employee has registered for both recreational activities and gym memberships is 1/40.

The term probability refers to the chance that an event will occur or not. The probability of an event always lies between zero and 1.

Given that;

Number that registered for recreational activities = 95

Number that registered for gym membership = 80

Number that did not register at all = 30

Total number of gym employees =200

Hence; 95 + 80 +30 =205

Number that registered for both recreational activities and gym membership

= 205 - 200 =5

The probability that an employee has registered for both recreational activities and gym memberships is; 5/200 = 1/40
