A card is drawn from the cards numbered from 8 to 27, find the probability that drawn card is divisible by 6 or 7 without remainder.​

Answers

Answer:

1/4

Step-by-step explanation:

from 8 to 27, there are 5 number that are divisible by 6 or 7.

=>       12,14,18,21,24

=>       number of favourable outcomes = 5

=>       numer of possible outcomes = 20

probability = no. of favourable outcomes/ no. of possible outcomes

=>       probability = 5/20

Answers

Based on the amount that London deposited every month and the number of years involved, London would have $57,515.16.

How much would London have in 11 years?

The amount that London deposits every month is an annuity because it is a fixed amount.

The value in 11 years is therefore the future value of an annuity which can be found as:

= Amount x ( (1 + rate) ^ number of periods - 1) / rate

The number of periods is:

= 11 years x 12 months

= 132 months

Future value is:
= 320 x ( ( 1 + 0.45%)¹³² - 1) / 0.45%

= $57,515.16

Class A has 28 pupils and class B has 8 pupils.
Both classes sit the same maths test.
The mean score for class A is 34.
The mean score for class B is 78.
What is the mean score (rounded to 2 DP) in the maths test across both classes?

Answers

Answer:

43.78

Step-by-step explanation:

In this case, the formula for mean can be as followed:

[tex]mean = \frac{sum \: of \: all \: student \: scores}{number \: of \: students} [/tex]

Let the sum of all student scores for class A and class B be A and B respectfully,

For Class A,

A/28 = 34

A/28 = 34A = 952

For Class B,

B/8 = 78

B/8 = 78B = 624

Now to find the mean score of both classes using the same formula,

Mean = (952+624)/(28+8)

= 43.77777777777778

≈ 43.78

Put the equation below into vertex form.

y=(x+9)(x+25)

Answers

Answer: (-17,-24)
Explanation: y= x^2+34x+225
a=1, b=34
X= - 34/2+1
x = -17
Y= (x+9)(x+25), x=-17
Y=-64
So vertex is (-17,-64)
If you put the equation into standard form and use point of symmetry formula to find the vertex you can answer the problem.

standard form:
y = ax^2 + bx + c
y = x^2 + 34x + 225
a=1 b=34 c=225

point of symmetry formula:
x = -b/2a
x = -34/2
x = -14

plug in x to find the vertex

y = (-14+9)(-14+25)
y = (-5)(11)
y = -55

vertex = (-14,-55)

vertex form
y = a(x-h)^2 + k [where (h,k) is the vertex]

so your answer is:

y = 1(x-(-14))^2 + (-55)

or

y = (x+14)^2 - 55

First, fill in 3 boxes of the table using the given information (blue numbers on the attached table)

"Of the 32 students that have a cell phone, 19 students do not have a tablet."

The top row of the table is students who have a cell phone.  Therefore, place 19 in the box in this row that is in the "no tablet" column.

"Of the 70 students that have a tablet, 57 students do not have a cell phone."

The first column of the table is students who have a tablet.  Therefore, place 57 in the box in the 2nd row of this column.

"11 students do not have a cell phone or a tablet."

Find the "no cell phone" row and the "no tablet" column and place 11 in the box that coincides.

We can calculate the blank totals using addition (shown by green numbers on the attached table)

Total students with no cell phone = 57 + 11 = 68Total students with no tablet = 19 + 11 = 30

To calculate the number of students who have a cell phone AND a tablet:

⇒ Total students with a cell phone minus students with a cell phone but no tablet

⇒ 32 - 19 = 13

what is an easy method to workout 35% of 70

Answers

Step-by-step explanation:

[tex]70 \times \frac{35}{100} = 24 .5 [/tex]

Answer:

24.5

Step-by-step explanation:

35% can be broken down into 10% + 10% + 10% + 5%

To find 10% of 70, divide 70 by 10.

To divide a number by 10, move the decimal point 1 place to the left.

⇒ 70 ÷ 10 = 7

So 10% = 7

5% is half of 10%

⇒ 5% = 7 ÷ 2 = 3.5

Therefore,

10% + 10% + 10% + 5% = 7 + 7 + 7 + 3.5

                                    = 21 + 3.5

                                    = 24.5

In order to factor this expression, we should factor out the common term (divide all terms in the polynomial by the common term)

In this case, the common term is

4

Note:- Usually, we factor out the G.C.F. (Greatest Common Factor)

So here, the G.C.F. is 4.

Why 4? Because in this trinomial (a polynomial with 3 terms) all 3 terms are divisible by 4.

So divide all the terms

5x

3y

-7

Put 4 outside the parentheses:

4(5x+3y-7)

Is the trinomial in its simplest form? Sure!

Compare the graphs that jennifer and matt drew by completing the statements. jennifer’s graph is vertically shifted from matt’s graph. jennifer’s graph is horizontally shifted from matt’s graph. jennifer’s graph is matt’s graph. which graph has a vertex that is a maximum?

Answers

Jennifer’s graph is vertically shifted from Matt’s graph by 2 units. and none of the graphs has their vertex at maximum.

What is a Function?

A function assigns the value of each element of one set to the other specific element of another set.

The function of the graph that is drawn by Jennifer is f(x)=2x²+4x, while the function that is drawn by Matt is g(x)=2(x+1)².

If we compare the function of the two graphs,

[tex]g(x)=2(x+1)^2\\g(x)=2(x^2+1+2x)\\g(x) = 2x^2+2+4x\\\\f(x)=2x^2+4\\[/tex]

As we can see that the only difference between the two of the function is +2, therefore, the only difference between Jennifer's graph and Matt's graph is that the graph of Jennifer’s graph is vertically shifted from Matt’s graph. As shown in the below image.

Thus, Jennifer’s graph is vertically shifted from Matt’s graph by 2 units.

If we draw two of the graph on the graph we will notice that the two of the functions will have their maximum at their vertex, as both graphs are opening upwards.

Hence, Jennifer’s graph is vertically shifted from Matt’s graph by 2 units. and none of the graphs has their vertex at maximum.

A triangle has two sides of length 19 and 18. What is the largest possible whole-number length for the third side?

Answers

Answer:

36

Step-by-step explanation:

For the largest possible whole number length, this means it would have to be the longest side. Let's let this third side have a length of x.

By the triangle inequality theorem, 19+18>x, which means x<37.

So, the largest possible whole number length for the third side is 36.

Given a grid with 15 sections, determine how many sections in the grid need to be shaded so the probability of a point chosen at random in the shaded area is exactly 0. 8. Explain your reasoning.

Answers

12 shade out of 15 boxes which gives 0.8 chance of picking a shaded one.

What is the probability?

Probability refers to a possibility that deals with the occurrence of random events. The probability of all the events occurring need to be 1.

The formula of probability is defined as the ratio of a number of favorable outcomes to the total number of outcomes.

There are 15 sections given

To make the probability of choosing a shaded section randomly 0.8,

So,

0.8 of 15

0.8 is equal to 80%

we need to figure out 80% of the 15

80% of 15

80% × 15

= 12

Hence, we would need to shade 12 out of 15 boxes which gives 0.8 chance of picking a shaded one.
