a)1/4 × £42 = £(42/4) = £10.50
__
b)2/5 × £13.50 = £(2·13.50/5) = £(27/5) = £5.40
_____
Additional comment
The symbol "£" is a currency symbol identifying the units of the associated number. For algebraic purposes, any symbol representing units can be treated as though it were a variable.
In this question of means multiplication.
Let us start solve this question
Question 1
[tex] \small\rm{ \dfrac{1}{4} \: of \: £ \: 42}[/tex]
First we will convert whole number into a fraction
(Any number can be converted to fraction if you use 1 as the denominator)
[tex] \small\sf{ \dfrac{1}{4} \: \times \: \dfrac{42}{1}}[/tex]
Now we will multiply the numerators and denominators.
[tex] \small\sf{ \dfrac{42}{4} = £10.50 } [/tex]
Question 2
[tex] \small\rm{\dfrac{2}{5} \: of \: £ \: 13.50}[/tex]
First we will convert whole number into a fraction
[tex] \small\sf{ \dfrac{2}{5} \times \dfrac{13.50}{1} } [/tex]
Now we will multiply the numerators and denominators.
[tex] \small\sf{ \dfrac{27}{5} =£ 5.40 } [/tex]

a) 0.52
b) 0.09
c) 0.26
d) 0.01
Answers
The probability that they have a mean salary between $40,000 and $50,000 is 0.01.
What is Z- score test?A z-test is a statistical test to determine whether two population means are different when the variances are known and the sample size is large.
The z-score for 40,000 is
= (40,000 - 66000) / (14,000 / √4)
= -26000/7000
= -3.714, P- value is 0.000102
The z-score for 50,000
= (50,000 - 66,000) / (14,000 / √4)
=-2.285, P- value is 0.0111564
P(40,000 < x < 50,000) = P( -3.714< z < -2.285)
So,
= P(50,000)-P(40,000)
= 0.0111564-0.000102
=0.011
Hence, the probability that they have a mean salary between $40,000 and $50,000 is 0.01.

Answer:
x=12
Step-by-step explanation:
Every triangle has interior degrees that all together add up to 180. We already know we have 50 degrees and 75 degrees, so we can subtract that to see how much we have left to work with. If we do that, we get 55 degrees left. Now, we have to set up a two step equation to find x:
5x-5=55
The first thing to do is to add 5 to both sides to get rid of -5:
5x-5=55
+5 +5
__ __
0 60
So now, it's 5x=60
Now, we have to isolate x. To do this, we have to divide both sides by 5. If you do this, you get:
x=12
Hope this helped!
Answer: b) x = 12
Step-by-step explanation:
The sum of a triangle's angles add up to 180°. We will add together all the angles, set them equal to 180°, and then solve.
Given:
(50°) + (75°) + (5x - 5°) = 180°
Combine similar terms:
120° + 5x = 180°
Subtract 120° from both sides of the equation:
5x = 60°
Divide both sides of the equation by 5:
x = 12

The five number summary of a dataset was found to be:
45, 52, 56, 61, 69
Answers
Step-by-step explanation:
Given the five summary of a data set:
45 - min
52 - Q1
56 - Median
61 - Q3
69- Max
Thus, any number less than Q1-(1.5×IQR)
, or any number that is greater than
Q3+ (1.5 × IQR) would be considered an outlier.
The IQR of the data set = Q3 - Q1 = 61-
52 = 9
Thus,
Q1- (1.5 × IQR) =52- (1.5* 9) = 52 - 13.5=38.5
Therefore, an observation is considered
an outlier if it is below: 38.5
Q3 + (1.5 * 1QR) = 61 + (1.5 * 9) =61+13.5 =74.5
Therefore, an observation is considered
an outlier if it is above: 74.5

PLEASSEEEE HELP ASAP , WHAT IS THE SHAPE OF THE BASE AND SURFACE AREA?
Answers
Answer:
Total surface area : 733
The shape of the base is a rectangle with sides 11 in. and 12 in.
Step-by-step explanation:
The shape of the base is a rectangle with sides 11 in. and 12 in.
The surface area is the sum of the areas of the 5 sides.
Area of the base = 11*12 = 132
Area of the two triangles = (11*16)/2 = 88
Area of the back rectangle = 192
The theorem of Pitagora to find the oblique side: square root of (11*11 + 16*16)= 19.42 in.
So the area of the oblique face: 19.42* 12 = 233 (almost :) )
So total surface area: 132 + 88*2+192+233= 733 square in
