Mrs. Daly's reading classes were surveyed about their reading preferences. The data is summarized in the table below.

geniusboy [140]

Count the total number of students who prefer fiction novels: In 9th grade there are 35, in 10th grade there are 52, so there are 87 students who prefer fictions. The proportion of 10th grade students out of these 87 students is 52/87=0.60 approximately.

The owner of a new restaurant wants to have seating for more than 75 people. There is currently a

Fudgin [204]

Answer:

$4m+3>75$

Step-by-step explanation:

Given:

Number of people to be seated should be greater than 75.

Let $n$ be the number of people. So,

$n > 75$

Now, there is a single private chef's table that can seat 3 people.

Tables bought by the owner = $m$

Number of people seated in 1 table = 4

So, number of persons that can be seated in $m$ tables = $4\times m=4m$

Now, total number of persons that can be seated in these two types of tables is the sum of 3 and $4m$

Therefore, $n = 4m+3$

But, $n>75$

Hence, the inequality to show the situation is:

$4m+3>75$

Let U={x: x is an integer and 2≤x≤10}. In each of the following cases, find A,B and determine whether A⊆B,B⊆A, both or neither:

12345 [234]

A is not a subset of B but B is a subset of A (that is can be found in A) that is B⊆A is correct

<h3>Set theory</h3>

Set is defined as the arrangement of elements. They can be represented using the venn diagram.

Given the following sets

U = {x: x is an integer and 2≤x≤10} = {3, 4, 5, 6, 7, 8, 9}
A = {x: 2x+1>7} = {x > 3}

B={x: x^2>20} = {x >± 20}

From the set, can see that A is not a subset of B but B is a subset of A (that is can be found in A) that is B⊆A is correct

Transformation Rule:<br> Translate 4 units right and 3 units up.<br> B<br> Х<br> A

Vera_Pavlovna [14]

Answer:

Step-by-step explanation:

Translation of a point (h, k) by 'a' units to the right and 'b' units upwards is defined by,

(h, k) → (h + a, k +b)

Coordinates of A → (-4, -2)

Coordinates of B → (1, -1)

Coordinates of C → (0, -5)

If these points are shifted 4 units right and 3 units up,

By applying rules of the translation,

Coordinates of image point A' → (-4 + 4, -2 + 3)

→ (0, 1)

Coordinates of B' → (1 + 4, -1 + 3)

→ (5, 2)

Coordinates of C' → (0 + 4, -5 + 3)

→ (4, -2)

Now plot these points on the graph.
