How to solve the blank

Answer: 11/3

Step-by-step explanation:

1. Distribute the 8: 16x + 24x + 16 = 4x + 148

2. Combine like terms: 40x + 16 = 4x + 148

3. Get the x by itself: 36x = 132

4. Divide by 36: x = 11/3

Using the uniform distribution:

a) The height of the density function which is f(x) is [tex]\frac{1}{12}[/tex]

We know that for a uniform distribution we have two bounds, namely a and b. The probability or likelihood of finding a value of at lower than x is given by the following formula:

P (X < [tex]x[/tex]) = [tex]\frac{x-a}{b-a}[/tex]

Now where we have been mentioned that the two bounds are as follows:

a = - 5 (lower bound)

b = 7 (upper bound)

a) To find the height (h) of the density function we use the below given formula:

h = [tex]\frac{1}{b-a}[/tex]

Putting here the values of a and b we get the height as,

∴ h = [tex]\frac{1}{7-(-5)}[/tex]

⇒ h = [tex]\frac{1}{7+5}[/tex]

⇒ h = [tex]\frac{1}{12}[/tex]

Hence, the height of the density function f(x) is [tex]\frac{1}{12}[/tex]

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]

Charlie paid $13.2 for the shorts after discount

The regular price of pair of shorts = $24

Discount during the sale on shorts = 45%

Discounts are price reductions that store owners make on items or services that are otherwise priced as marked. This portion of the rebate is typically provided to boost sales or get rid of excess inventory. The price of an item as stated by the manufacturer or seller, without any price reduction, is known as the List price or Marked Price.

Amount of discount = 45% of 24

= 45/100*24

= 10.8

Amount of shorts after discount = Regular price of shorts - Discount on shorts

= 24 - 10.8

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

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

Part A:

Add all the values:

Convert the oz into pounds:

1oz = 16 pounds

Divide each value by 16:

55 oz = 55/16 = 0.3125 pounds

11 oz = 11/16= 0.6875 pounds

14 oz = 14/16 = 0.875 pounds

1 pound = 1 lb

3 3/4lb= 3.75 lb

2 1/4 = 2.25 lb

2lb

Now add:

Total weight = 3.75 + 0.3125+ 2.25+0.6875+0.875 = 7.875 lb

The length of the minor axis of the ellipse described by the equation in the task content is; 6.

It follows from the task content that the length of the minor axis of the ellipse is to be determined.

Since the equation given in the task content is;

x² + 4y² = 36.

By dividing both sides by 36; we have;

(x²/36) + (y²/9) = 1

By expressing the denominators as squares; we have;

x²/6² + y²/3² = 1

By comparison of the equation above with the standard equation of an ellipse; x²/a² + y²/b² = 1 where; a = major axis and b = minor axis.

a = 6 and b = 3.

Ultimately, the length of the minor axis is given by; 2b = 2 × 3 = 6.

At (9, 0), the graph of the equation y = - 2/3 x + 6 intersect the x - axis.

How to create linear equation using two variables?
If an equation is written in the form ax + by + c=0, where a, b, and c are real integers and the coefficients of x and y, i.e., a and b, respectively, are not equal to zero, then it is said to be a linear equation in two variables. Such an equation has a pair of numbers as its solution, one for x and one for y, which further equalizes the two sides of the equation. A specific point on the graph represents the solution of a linear equation in two variables, ax + by = c, where the total of these two values will equal c when the x-coordinate is multiplied by a and the y-coordinate by b. Basically, there are infinitely many solutions to a linear equation with two variables.
The linear equations can be solved using substitution method.

Given, the equation of the graph is : y = (-2/3) x + 6 -(i)
Also, the equation of x-axis is: y = 0 -(ii)
Substituting (ii) in (i), we get,
0 = (-2/3)x + 6 ⇒ (-2/3)x = -6 ⇒ (2/3)x = 6 ⇒ x = 9
Thus, the point where the graph of the equation y = - 2/3 x + 6 intersect the x - axis is (9, 0).
