Nkateko sells bananas at the low but fixed price of R3/kg. In order to ensure that she makes a reasonable profit, she adds a certain fixed amount of money to any quantity of bananas purchased. A customer who bought 4 kg of bananas was observed paying R14.

Answers

Answer:

The profit for any purchased of bananas is R2.

Step-by-step explanation:

Cost of 1 kg banana = R 3

Banana purchased = 4 kg

So, the cost of 4 kg bananas = 4 x 3 = R 12

Amount paid = R 14

Profit = R 14 - R 12 = R 2

So, the profit on any purchased of bananas is R 2.

What is the 11th term of the sequence 7, -21, 63

Answers

Answer: 413343

Step-by-step explanation:

This is a geometric progression. First and foremost, we've to find the common ratio which will be:

= 2nd term / 1st term

= -21/7

= -3

The formula to find the 11th term will be:

= ar^n-1

where,

a = first term = 7

r = common ratio = -3

n = number of terms = 11

Therefore, ar^n-1 = 7 × -3^11-1

= 7 × -3^10

= 7 × 59,049

= 413343

Therefore, the 11th term of the sequence is 413343.

The flags are all the same size and are space equally along the line. Calculate the length of the sides of each flag, and the space between flags by making a system of equations and solving that system..

Answers

Answer:

Step-by-step explanation:

Let the space between flags be "x" and the flag's side is "y"

2x + 3y = 80   ║ × ( - 2 )

5x + 6y = 170

- 4x - 6y = - 160 ..... ( 1 )

5x + 6y = 170 ..... ( 2 )

( 1 ) + ( 2 )

x = 10

2(10) + 3y = 80

y = 20

The space between flags is 10 cm

The flag's sides are the same size and is 20 cm

For students who first enrolled in a two year public institution in 2013, the proportion who earned a bachelor's degree in six years was 0.236. The president of a certain college believes that the proportion of students who enroll in her institution have a higher completion rate.
(a) Determine the null and alternative hypotheses.
(b) Explain what it would mean to make a Type I error.
(c) Explain what it would mean to make a Type II error.

Answers

Answer:

H0 : p = 0.236

H1 : p > 0.236

Type 1 error is committed by incorrectly rejecting a true null hypothesis

Type 11 error is committed by incorrectly accepting a false null

Step-by-step explanation:

The null and alternative hypothesis :

H0 : p = 0.236

H1 : p > 0.236

A type 1 error is made when a null hypothesis is incorrectly rejected, Hence in this scenario, a type 1 error will be committed of we conclude that the proportion who earned bachelor's degree is more Than 0.236 when the actual proportion not more than but equal to 0.236

A type 11 error is committed when we fail to reject a false null hypothesis. This means that if the actual proportion who earned a bachelor's degree is more than 0.236 and we fail to reject the null which says the proportion is not more than 0.236

How many 3 digits positive integers exist that when divided by 7 leave a remainder of 0

Answers

Answer:

128 numbers are divisible by 7 that leave remainder 0

Answer:

128

Step-by-step explanation:

Let's find the first 3 digit number divisible by 7.

7(12)=84

7(13)=91

7(14)=98

7(15)=105

So our first 3 digit number divisible by 7 is 105.

Let's figure out the last 3 digit number divisible by 7.

7(200)=1400

Skip a lot

7(150)=1050

Skip a little more

7(140)=980

Skipped too much

7(145)=1015

7(144)=1008

7(143)=1001

7(142)=994

So there are 142-15+1 multiples of 7 that are 3 digits long.

142-15+1

point and slope of the equation y - 8 = 4(x + 3)?

Answers

Use the Slope Intercept form y = mx + b to find the slope m and y-intercept b.

Slope : 4

Y-intercept : (0,20)


Hope this helps !

Have a great day :)

The slope and point of y-intercept is;

Slope = 4

Point of intercept = (0, 20)

We are given the equation;

y - 8 = 4(x + 3)

Now, the slope intercept form of the equation of a line is;

y = mx + c

where;

m is slope

c is y-intercept

x is value on the x-axis

y is value on the y-axis

Let us simplify our equation to the slope-intercept form;

y - 8 = 4(x + 3)

Expanding the bracket using distributive property gives;

y - 8 = 4x + 12

Using addition property of equality gives;

y - 8 + 8 = 4x + 12 + 8

y = 4x + 20

Comparing our result with y = mx + c,

m = 4 and c = 20

c is y-intercept which is value of y when x = 0.

Thus, intercept point is (0, 20)
