[tex]\sf \dfrac{1}{2}[/tex]

Step-by-step explanation:

Results from the slips of paper:

Total slips of paper = 16

[tex]\sf Proportion = \dfrac{part}{whole}[/tex]

[tex]\implies \textsf{Proportion of shoppers who were happy}=\sf \dfrac{8}{16}=\dfrac{1}{2}[/tex]

Answer:

1/2

Step-by-step explanation:

There are 16 responses

There are 8 people who said yes

P( happy) = yes/  total

P(happy) = 8/16 = 1/2

Answer:

D

Step-by-step explanation:

The median is 8, so it is less than 9.

Answer:

Option D is not true

Step-by-step explanation:

The mode is the highest occuring number.From the data.

The mode is 9 and is greater than 7.This mean option A is correct.

The range is the difference between the highest number and the lowest which is 15-4 =11.Hence option C is correct because the range is more than 10.

The median when the data is arranged in either ascending or descending order i.e (15,12,11,9,9,7,5,4).Hence,the middle numbers are 9 and 9.To get the median,we get the average of the numbers which will be 9+9=18 ÷2= 9. The median is 9 which means option D is not correct.

The mean will be the addition of the numbers divided by the number of items

[tex] \frac{9 + 15 + 5 + 7 + 9 + 12 + 11 + 4}{8} [/tex]

[tex] = \frac{72}{8} [/tex]

[tex] = 9[/tex]

The mean is equal to 9 which means Option B is correct.

This implies that the only option which is incorrect is option D

Answer:

x = 20

y = √3 / 10

Step-by-step explanation:

The cosine ratio gives the ratio between the adjacent side and the hypotenuse.

The sine ratio gives the ratio between the opposite side and the hypotenuse.

Taking cosine ratio to find x :

cos 60° = 10/x

1/2 = 10/x

x = 20

Taking sine ratio to find y :

sin 60° = y/x

√3 / 2 = y/20

y = √3 / 10

Answer:

x= 20 ,  y= 10√3

Step-by-step explanation:

This question is clearly a trigonometry question

Please bare in mind :

Cos 60 = 1/2

Sin 60 = √3/2

Tan 60 = √3

Side x is the hypotenuse (h)

Side y is the Opposite (o)

And side with length of 10 is adjacent (a)

To find x, we have a, and we need h

So we use C = a/h

Cos 60 = 10/h

h = 10/Cos 60

h = 10/0.5

h = 20 ,  x=20

To find y, we can use pythagaros as we found the value of x :

10² + y² = x²

10² + y² = 20²

y² = 20²-10²

y² = 300

y = √300

y= √100×3   y=√100 × √3

y = 10√3

This is our y value

Another way to find y is trigonometry :

We have a and we need o so we use :

T = o/a

Tan 60  = o/10

o = 10×tan 60

o = 10×√3

o = 10√3 ,  y=10√3

Step-by-step explanation:

Surface Area :

⇒ Area (4 triangle faces) + Area (square base)

⇒ 4 x 1/2 x 5 x 7 + (5)²

⇒ 2 x 35 + 25

⇒ 70 + 25

⇒ 95 square centimeters

The interval for the function to be negative will be (-∞<x<-7).

A function in mathematics set up a relatioship between the dependent variable and independent variable. on changing the value of the independent variable the value of the dependent variable also changes.

Here we have a function:-

g(x) = ∛(x+6)

If we put the value of x lesser than 6 in the function we will always get a negative value so the interval will be:-

(-∞<x<-7).

Therefore interval for the function to be negative will be (-∞<x<-7).

Answer: a) 7mm  b) 18mm  c) 49mm

Step-by-step explanation:

There are 10 mm in 1 cm, so to find how many mm the measurements are, multiply the measurement in cm by 10.

a) 0.7 cm

0.7 cm x 10 mm per cm = 7 mm

b) 1.8 cm

1.8 cm x 10 mm per cm = 18 mm
