The required amount of stock is of $950 for  both brokers charge the same commission from the linear equation in one variable.

Let the total amount of stock be x (in dollars).

Fierro Brothers charges their customers a $19 flat fee per trade. Whereas, the Sondo Investment House charges 2% as the commission of trade.

Thus the given condition is Fierro Brothers charges equal commission fee on the required amount of stock as Sondo Investment house.

This relation can be shown in terms of linear equation as,

19 = 2% of x

⇒ 19 = (2/100)x

This linear equation is in the form of linear equation in one variable.

⇒ x= 19*(100/2)

⇒ x = 950

Therefore, on single trade of stock of $950 Fierro Brothers charges $19 fee (flat) as their commission which is equal to the commission earned by Sondo Investment House at the rate of 2% on trade.

The probability that Tara selects 1 pen and then 1 marker is 6/30 (option b).

To solve this problem, we need to first find the total number of ways that Tara can select two items from the box without replacement.

In this case, we have n = 6 (3 pens, 2 markers, and 1 highlighter) and r = 2. Therefore, the total number of ways that Tara can select two items is:

6C2 = 6! / 2! (6 - 2)! = 15

Next, we need to find the number of ways that Tara can select a pen first and then a marker.

Therefore, the number of ways to select a pen first is 3, and the number of ways to select a marker second is 2. The total number of ways to select a pen first and then a marker is:

3 x 2 = 6

Finally, we can find the probability of selecting a pen first and then a marker by dividing the number of ways to select a pen first and then a marker by the total number of ways to select two items:

6 / 15 = 2 / 5

Therefore, the correct answer is option B) 6/30, which can be simplified to 2/5.

The missing measures for the triangle are given as follows:

Suppose we have a triangle in which:

The lengths and the sine of the angles are related as follows:

[tex]\frac{\sin{A}}{a} = \frac{\sin{B}}{b} = \frac{\sin{C}}{c}[/tex]

The sum of the measures of the internal angles of a triangle is of 180º, hence the measure of angle B is obtained as follows:

m < B + 73 + 42 = 180

m < B = 180 - 115

m < B = 65º.

Then the relation is:

34/sin(73º) = a/sin(42º) = b/sin(65º).

Then the value of a is obtained as follows:

34/sin(73º) = a/sin(42º)

a = 34 x sine of 42 degrees/sine of 73 degrees

a = 23.8.

The value of b is obtained as follows:

34/sin(73º) = b/sin(65º)

Answer:

Step-by-step explanation:

The small cafe offers 6 fewer types of pizza than a restaurant. The restaurant offers 18 different types of pizzas and the cafe offers 1/3 as many types of pizzas which means what we have to find 1/3 of 18.

1/3 of 18 is 6 because 6*3 is 18

18 - 6 = 12 which is the number of pizzas the cafe offers but this is slightly irrelevant to the question because the question is asking how many FEWER pizzas the cafe sells than the restaurant

So, the small cafe offers 6 FEWER pizzas than the restaurant.

[tex]4\frac{1}{5} cups[/tex]

Step-by-step explanation:

Let's start by setting up a ratio for the recipe.

First, rewrite 2 and 4/5 as an improper fraction.

[tex]2\frac{4}{5} = \frac{14}{5}[/tex]

We know that for every 2/3 cup of flour, we need 14/5 cups of sugar. So, our ratio will be:

[tex]\frac{2}{3} :\frac{14}{5}[/tex]

We want to find how many cups of sugar we'd need for 1 cup of flour. Let s represent the cups of sugar. Let's set up another ratio (flour to sugar):

[tex]1:s[/tex]

Now, since you're following the same recipe, let's set the ratios equal to make a proportion, like so:

[tex]\frac{2}{3} :\frac{14}{5} =1:s[/tex]

Multiply the means and extremes, set their products equal, and solve.

[tex]\frac{2}{3}s=\frac{14}{5}*1=\\s=\frac{3}{2} *\frac{14}{5} =\\s=\frac{21}{5}[/tex]

Let's turn 21/5 into a mixed number.

[tex]\frac{21}{5} =4\frac{1}{5}[/tex]

So, if you used one cup of flour, you would need [tex]4\frac{1}{5}[/tex] cups of sugar.

Answer:

(0.5, -0.5)

Step-by-step explanation:

To find the midpoint of A and B, we can use the midpoint formula. The formula involves finding the average of the x-coordinates and the average of the y-coordinates.

Midpoint formula: ((x1 + x2) / 2 , (y1 + y2) / 2)

Using the coordinates of A (-3, -5) and B (4, 4), we can plug them into the formula:

(((-3) + 4) / 2 , ((-5) + 4) / 2)

Simplifying this gives us the midpoint of A and B: (0.5, -0.5).

Therefore, the midpoint of A and B is at coordinates (0.5, -0.5).

The result of the vector multiplication of a scalar is a vector.

A vector has both magnitude and direction while a scalar has only magnitude and no direction.

When each element of the vector is multiplied by the scalar when a scalar and a vector are multiplied. The resulting vector is multiplied by the scalar, but it still has the same direction as the original vector.  Thus when we multiply the vector by the scalar what we get is a vector as we can see in this question.

The composite figure that has an area of 40 square yards would be composed of a rectangle and a triangle.

It is not true that when two composite figures have the same area, they must also have the same perimeter.

The composite figure is composed of a rectangle and a triangle placed side by side. The rectangle has a width of 5 yards and a length of 6 yards. The triangle is a right triangle with a base of 4 yards and a height of 5 yards.

Area Calculation:

The area of the rectangle is length × width = 5 yards × 6 yards = 30 square yards.

The area of the triangle is (1/2) × base × height = (1/2) × 4 yards × 5 yards = 10 square yards.

The total area of the composite figure is the sum of the rectangle's area and the triangle's area: 30 square yards + 10 square yards = 40 square yards.

I disagree with your friend's statement that when two composite figures have the same area, they must also have the same perimeter. It is possible for two composite figures to have the same area but different perimeters.

The scatter plot that shows a negative nonlinear association is option C.

A scatter plot is a type of graph that displays the relationship between two variables. It is used to show how much one variable is affected by another variable. One variable is plotted on the horizontal axis (x-axis) and the other variable is plotted on the vertical axis (y-axis).

Here,

In this scatter plot, as the x-axis values increase, the y-axis values initially increase and then decrease. This type of association is referred to as a negative nonlinear association, where the direction of the association is negative (decreasing) and the shape of the association is nonlinear (not a straight line). The other options either show a positive association (increasing values of x and y) or a linear association (a straight line).

Circumference of the circle or perimeter of the circle is the measurement of the boundary of the circle. Whereas the area of circle defines the region occupied by it.  If we open a circle and make a straight line out of it, then its length is the circumference. It is usually measured in units, such as cm or unit m.

A mountain bike tire completes 15 revolutions and travels 146 feet.

Now,

1 revolution of a tire is equal to the circumference of the tire.

Given question is having the wrong picture. I am attaching required correct picture as below,

Charlie jumped farther than his younger brother, by a distance of (60L + 35)/L - 81 feet.

To compare the distances that Charlie and his younger brother jumped, we need to find a common unit of measurement. We can convert the mixed numbers into improper fractions to make the calculation easier.

Charlie jumped 81/1 feet, which is the same as 81 feet.

His younger brother jumped 35/L feet and then 21 feet. We don't know the exact value of L, but we can still compare the distances by assuming L is a constant value. So, the total distance his younger brother jumped is:

35/L + 21 feet

We can simplify the expression by finding a common denominator:

(35 + 21L)/L feet

To compare the distances, we can subtract the distances jumped by Charlie and his younger brother:

81 - (35 + 21L)/L

To determine who jumped farther, we need to simplify this expression by finding a common denominator:

(81L - 35 - 21L)/L

Simplifying further:

(60L + 35)/L

We don't know the exact value of L, but we can say that if L is any positive value, then 60L + 35 is greater than 81. Therefore, Charlie jumped farther than his younger brother, by a distance of (60L + 35)/L - 81 feet.

In the event of shortening the standard error of mean to 15 we have to increase the size to 400. Therefore, the correct answer is Option B.

The  given standard error of the mean for a sample of 100 is 30. So to cut the standard error of the mean to 15, we have to proceed by increasing the sample size to 400.

The  formula for evaluating the standard error of mean
SEM = SD / √(n)
here, SEM = standard error of the mean,
SD = standard deviation
n = sample size
Staging the values
15 = SD / √(100)
15 x √(100) = SD
SD = 150
Now evaluating for the value of n
15 = 150 / √(n)
15 x √(n) = 150
√(n) = 10
n = 100
Now looking at the formula, we need to decrease SEM by half,
