The value of P(1.17 <= Z <= 2.26 ) is 0.1091

From the question, we have

Z value for 1.17 is 0.8790

Z value for 2.26 is 0.9881

P(1.17 <= Z <= 2.26 ) = 0.9881 - 0.8790 = 0.1091

Probability:

Probability refers to possibility. A random event's occurrence is the subject of this area of mathematics. The range of the value is 0 to 1. Mathematics has incorporated probability to forecast the likelihood of various events. The degree to which something is likely to happen is basically what probability means. You will understand the potential outcomes for a random experiment using this fundamental theory of probability, which is also applied to the probability distribution. Probability is a way to gauge how likely something is to happen. Many things are difficult to forecast with absolute confidence. Using it, we can only make predictions about the likelihood of an event happening, or how likely it is.

Considering the angle of elevations, the distance from point AA to point BB which is the height of the antenna is 5.34 meters

information given in the question

Mia stands at a horizontal distance of 15 meters from the building

The angle of elevation from her eyes to the roof ((point AA)) is 18

the angle of elevation from her eyes to the top of the antenna ((point BB)) is 53^

her eyes are 1.75 meters from the ground

The direction of movements describes a right angle triangle of

opposite = height of antenna + height of the building

adjacent = 15 meters

The  distance from point AA to point BB and the height of the antenna is worked using SOH CAH TOA

Sin = opposite / hypotenuse - SOH

Cos = adjacent / hypotenuse - CAH

Tan = opposite / adjacent - TOA

The  the height of the antenna is calculated using tan, TOA let the angle be x

tan x = Opposite / Adjacent

using 53 gives the height of the antenna + height of the building, while using 18 gives height of the building only

tan 53  = opposite / 15

opposite = 15 * tan 53 = 19.906 meters

opposite = 15 * tan 18 = 14.266 meters

Height of the antenna

= 19.606 - 14.266

= 5.34 meters

The number of cups that Mr Colton need to make 2 pounds of dough is 3.08 cups.

Ratio demonstrates how many times one number can fit into another number. Ratios contrast two numbers by ordinarily dividing them. A/B will be the formula if one is comparing one data point (A) to another data point (B). This indicates that you're dividing information A by B. For instance, the ratio will be 5/10 if A is 5 and B is 10

Let the number of cups be represented by x.

This will be expressed as:

2/3 = x/4.62

Cross multiply

3x = 2 × 4.62

3x = 9.24

By assuming that the initial height of the rocket is the ground, we will get the height equation:

H(t) = -16*t^2 + 235*t

The height equation for any object near the surface of the heart that is not being subject to any other forces than the gravitational one is:

H(t) = -16*t^2 + v*t + h

Where:

t represents the time in seconds.

the first coefficient -16 is half of the gravitational acceleration in feet over squared seconds.

v is the initial velocity, which in this case is 235 ft/s

h is the initial height, in this case we assume is zero (the rocket is launched from the ground)

Replacing all that in the height equation, we will get:

A and C are congruent angles opposite to congruent sides of the isosceles triangle.

Find the measure of ∠A

Answer:

The angle A is 55°.

Step-by-step explanation:

We know that,

→ <A = <C

Now the value of x will be,

→ 3x + 40 = x + 50

→ 3x - x = 50 - 40

→ 2x = 10

→ x = 10/2

→ [ x = 5 ]

Then the value of m<A is,

→ A = 3x + 40

→ A = 3(5) + 40

→ A = 15 + 40

→ [ A = 55° ]

Hence, the answer is 55°.

The straight line y = x -1 is shown figure  

To plot straight-line graphs we need to take values of x and y values to make a value table and to work out the graph.

Take x values as -1, 0, 1, etc. to make our work easy and clearer, and from that find the values of y.

After calculating the coordinates, use the resultant points to plot the line as a graph.  

Here we have a line

y = x -1  

To sketch the graph we need to make a value table as given below

First take x values as, -1,  0, 1 from that find the values of y  

At  x = -1 => y = -1 - 1 = -2

At  x = 0 => y = 0 - 1 = -1

At  x = 1 =>  y = 1 - 1 = 0  

From the above calculations, the value table is

        x   -1   0   1

        y   -2  -1  0

Equation of the line is y = 3/2x + 3.

Y = mx+b, where m is the slope and b is the y-intercept, is the formula for the slope-intercept form (the point where the line crosses the y-axis). The line with m as the slope, m and c as the y-intercept is the graph of the linear equation y = mx + c. The values of m and c are real integers in the slope-intercept form of the linear equation. The "slope-intercept" form is one of the most popular methods. It is so named because it makes the slope and y-intercept of the equations in the equation more clear.

In the given question,

We have to find the image of (-9,12) after a dilation by a scale factor of 1/3 centered at the origin.

Since we have to find the image after a dilation.

So we learn about it now,

Any scale factor will dilate the image of any coordinate. A specific scale factor can be used to scale the coordinate up or down. To determine the answer, consider the scale factor in the equation and multiply or divide the coordinates of dilation by the appropriate scale factor.

So the given point is (-9,12).

Scale factor is 1/3.

So the image of (-9,12) after a dilation by a scale factor of 1/3 centered at the origin is define as

=(-9×1/3,12×1/3)

2050 kg/1 m³ × 2.2 lb/1 kg × 1 m³/35.3 ft³ = 127.76 lb/ft³.

In Mathematics, a conversion factor simply refers to a number that is typically used to convert a number in one (1) set of units to another, either by dividing or multiplying.

Generally speaking, an appropriate conversion factor to an equal unit of value must be chosen and used when it is necessary to perform any mathematical conversion.

Conversion:

2050 kg/1 m³ × 2.2 lb/1 kg = 4,510 lb/1 m³

4,510 lb/1 m³ × 1 m³/35.3 ft³ = 4,510 lb/35.3 ft³

4,510 lb/35.3 ft³ = 127.76 lb/ft³.

According to the scatter plot provided, the weight for someone who is 1.5 meters tall is predicted to be 45.45 kilograms.

A line of best fit is also referred to as a trend line and it can be defined as a statistical and analytical tool that is used in conjunction with a scatter plot, in order to determine whether or not there's any association (correlation) between a data.

In this scenario, the weight (in kilogram) would be plotted on the y-axis of the scatter plot while the height (M) would be plotted on the x-axis of the scatter plot.

From the scatter plot (see attachment) which models the relationship between data points in the table, a linear function for the line of best fit is given by:

Weight, kg = -114.3 + 106.5M

When M = 1.5 meters, we have:

A relation that represents a function will have each of its domain elements related to exactly one range element.

All the x-values in a relation are referred to as the domain of a function, while all the y-values are called the range of the function,

Therefore, for a relation to be considered a function, a domain element must not correspond to two different range elements or related to two range elements.
