Inserting brackets to make the statement true 10 + 2 x 3^2 - 2 = 84 will be (10 + 2) × (3² - 2).

It should be noted that the information simply means that one had to put the bracket in the appropriate places on order to get the value of 84.

This will be illustrated thus:

= 10 + 2 × 3² - 2

= (10 + 2) × (3² - 2)

= 12 × (9 - 2)

= 12 × 7

= 84

Therefore, the expression is true.

the number chosen by Janet was 9 .

An equation is a statement in which the values of two mathematical expressions are equal. These statements consist of constants and variables. Constants are values that never change. Variables like y or x represent unknown numerical values. Nonlinear equations are equations that appear as curved lines when you graph them. After plotting pairs of values that make the equation true on a coordinate grid, you can't draw a straight line between the points.

from the question given we can come to an equation that is

2( x+7) - 4 = 28

if the number chosen by Janet is x

lets find x

2x + 14 - 4 = 28

2x = 18

x = 9

therefore the number chosen by Janet was 9 .

While graph A shows a Strong Negative Correlation (Option E), Graph B shows a No Correlation. (Option C)

A significant negative correlation, on the other hand, suggests a substantial relationship between the two variables, but that one rises while the other falls. For example, a correlation of -0.97 suggests a high negative connection, whereas a correlation of 0.10 shows a mild positive correlation.

A scatter plot, also known as a scatter graph or scatter chart, employs dots to represent the values of many numerical variables. To demonstrate a weak positive association, the value of Y grows slightly as the value of X increases.

The equation of the line. a line that is parallel to the graph of 2x+3y=5 and contains the point (3,-1) is y+1 = -2/3 (x - 3)

A line is defined by the shortest distance between two points,

The equation of a line in point slope form is expressed as;

y - y₁ = m(x-x₁)

where

m is the slope

(x₁, y₁) is any point on the line

Given the following parameters

Point = (3, -1)

Given the equation 2x + 3y = 5

3y = -2x + 5

y = -2/3x + 5

Slope = -2/3

Substitute

y - (-1) = -2/3(x-3)

y+1 = -2/3 (x - 3)

Answer:

24 inches

Step-by-step explanation:

[tex]a^{2}[/tex] + [tex]b^{2}[/tex] = [tex]c^{2}[/tex]

[tex]18^{2}[/tex] + [tex]b^{2}[/tex] = [tex]30^{2}[/tex]

324 + [tex]b^{2}[/tex] = 900

[tex]b^{2}[/tex] = 576

[tex]\sqrt{b^{2} }[/tex] = [tex]\sqrt{576}[/tex]

b  = 24

Answer:

24 inches

Step-by-step explanation:

Since the size of the screen is measured from the lower corner to the opposite upper corner.

therefore it forms a right angled triangle.

given hypotenuse is 30inch

the height is 18 inches

using the Pythagorean theorem

[tex] {hypotense}^{2} = {width}^{2} + {height}^{2} [/tex]

then

[tex] {30}^{2} = {width}^{2} + {18}^{2} \\ 900 = {width}^{2} +324[/tex]

Subtract 324 from both sides

[tex]576 = {width}^{2} \\ width = \sqrt{576} = 24 \: \: inches[/tex]

For the given discrete data series,

Median = 4'7"

Mode = 4'8"

Range = 1'3"

To begin with, let us arrange the given discrete data series in ascending order as follows:

3'7"     3'11"    4'3"    4'6"      4'7"      4'7"     4'8"      4'8"      4'8"     4'9"   4'10"

To identify the median, locate the data point that stands exact at midpoint of the series. It is the sixth entry from left and hence median = 4'7"

To identify the mode, count and identify which data points occurs highest in frequency. 4'8" is mode as it occurs highest number of times (3 times) in the series.

To calculate the range, we subtract the last entry. Thus Range = 4'10" - 3'7" = 1'3"

The equation to find the elapsed time is  -16t^2 + 20 + 15 = 0 and the elapsed time is 1.479 seconds

The given parameters are:

h(t) = -16t^2 + 20

Also, we have:

Safety net = 15 feet below

This means that

h(t) = -15

Substitute h(t) = -15 in h(t) = -16t^2 + 20

So, we have

-16t^2 + 20 = -15

Add 15 to all sides

-16t^2 + 20 + 15 = 0

Using a graphing calculator, we have

t = -1.479 and t = 1.479

Time cannot be negative

So, we have

t = 1.479

Hence, the time is 1.479 seconds
