Answer:

x = 7

Step-by-step explanation:

(10x - 2) and (9x + 5) are corresponding angles and are congruent , then

10x - 2 = 9x + 5 ( subtract 9x from both sides )

x - 2 = 5 ( add 2 to both sides )

x = 7

The probability that the sample mean would be greater than 101.5 gallons

P(x>101.5)=0.9382

This is further explained below.

Generally, From this population, a sample with the size n=38 is taken and analyzed.

Let's say that x is the sample's mean value.

It may be concluded that the sample distribution of the x-bar is about normal with

Mean =103

Standard deviation=0.9733

Now, the expression for the probability looked for is P(x>101.5)

[tex]=&\mathrm{P}\left[\left(\bar{x}-\mu_{\bar{x}}\right) / \sigma_{\bar{x}} > \left(101.5-\mu_{\bar{x}}\right) / \sigma_{\bar{x}}\right][/tex]

Where

P=Probabilty

x=mean

[tex]\mu[/tex] is population mean

[tex]\sigma[/tex]= Standard deviation

[tex]\\&=\mathrm{P}\left[\left(\bar{x}-\mu_{\bar{x})} / \sigma_{\bar{x}} > (101.5-103) / 0.97332852678\right]\right.\end{aligned}[/tex]

= P[Z > -1.54]

P(x>101.5)=0.9382

-11 degrees is the expected daytime temperature for today

The daytime temperature yesterday in Montana = -4.5 degrees

Expected temperature drop today = 6.5 degrees

The term "temperature" describes how hot or cold the atmosphere is and is measured with a thermometer. Temperature is reported by meteorologists in both Celsius (C) and Fahrenheit (F).

Today's expected daytime temperature:

The daytime temperature yesterday in Montana + Expected temperature drop today

But since the temperature of yesterday is negative we will use a negative sign to add the expected temperature of today. A drop in temperature will lead to a more cold temperature

= -4.5 + (-6.5)

= -11 degrees

The cost of each bottle of juice is $0.51.

The tape diagram can be used to illustrate the relationship between the numbers that are given.

Let the cost of each bottle of juice be x.

In this case, she bought a bag of oranges for $2.19 and a 12-pack of juice bottles and the total cost before tax was $8.31.

This will be:.

2.19 + 12x = 8.31

Collect like terms

12x = 8.31 - 2.19

12x = 6.12

Divide

x = 6.12 / 12

x = 0.51

The cost is solved. Note that the tape diagrams weren't given but the.coat is solved accordingly.

The equation which is best representing the height above ground, y, of the model rocket and x seconds after it reaches the maximum height is 75x + y = 2000.

The height above ground, y, of the model rocket, x seconds after it reaches its maximum height can be represent by a linear equation,

The maximum height is 2000 feet, after this the rocket starts to descend with a rate of 75 feet per second.

Let us say that when the rocket starts descending, our time is started from zero,

So, on plotting these points of graph, we can one point, (0,2000).

The rate of descend is the slope m of the graph,

m = -75 ft/s

We are taking it negative because height is decreasing with time,

We can use the point slope form of equation of line,

It says, if a line passes through (a,b) and has slope m. Then the equation of line is,

(y-b) = m(x-a)

So, our line is passing through (0,2000) and has slope -75 ft/s.

So, equation of the line is,

(y-2000) = -75(x-0)

75x + y = 2000.

This above equation of line is representing the relation between the height above ground and time of the model rocket.

Correlation is not sensitive to the scale of the data; however, covariance is  sensitive to the scale of the data, so the statement is false.

Covariance is a term used in statistic and regression analysis. Covariance shows how two variables differ.

Covariance is affected by the change in scale, for example if all the value of one variable is multiplied by a constant and all the value of another variable are multiplied, by the same or another constant all together, then the covariance is automatically changed.

Correlation is also a term used in regression analysis and statistics. Correlation shows how two variables are related and therefore not influenced by the change in scale.

Hence the given statement is False

Nina bought 3.45 pounds of walnut.

Nina bought 1.62 pounds more walnut than almonds

Quantity of pecan bought by Nina = 1.725 pounds

Quantity of almonds bought by Nina = 1.83 pounds

The process of comparison of numbers establishes the similarities between two numbers and determines which number is greater, smaller, or equal to another number.

Quantity of walnuts = 2*Quanitity of pecans

= 2*1.725

= 3.45 pounds

So, she bought 3.45 pounds of walnut

Pounds of walnuts bought more than the almonds = Quantity of walnuts bought by Nina - Quantity of almonds bought by Nina

= 3.45 - 1.83

= 1.62 pounds

So, she bought 1.62 pounds more walnuts than almonds

Step-by-step explanation:

The percent recovery of benzoic acid is equal to 80.0 if the mass of purified benzoic acid after recrystallization is 1.611 g.

The percent recovery can be described as the amount of a product available after its production and purification.

The percent recovery of benzoic acid can be calculated by using the following formula:

percent recovery of sample = (Mass of purified sample ÷ Mass of contaminated sample) × 100

Substituting the given values of contaminated and purified benzoic acid in this equation;

percent recovery = (1.611 ÷ 2.014) × 100

percent recovery = 0.7999 × 100

percent recovery = 79.99

Rounding it to the nearest tenth;

percent recovery = 80.0

Hence the percent recovery of benzoic acid is calculated to be 80.0

The temperature at 7 P.M is 32 °F.

Fahrenheit temperature scale, scale based on 32° for the freezing point of water and 212° for the boiling point of water, the interval between the two being divided into 180 equal parts.

Given that,

Temperature at noon = 45 °F

At 7 A.M. the temperature was 17°F colder = 45-17

                                                                      = 28 °F

The temperature at 7 P.M. Was 4°F warmer than at 7 A.M

= At 7 A.M. the temperature was 17°F colder +  4°F
