C. Data is organized in equal intervals. i think

Step-by-step explanation:

The correct statement about histograms is that data is organized in equal intervals. A histogram represents data through bars of different heights, corresponding to their frequency, grouped into specified ranges.

In regards to histograms in mathematics, the true statement is: C. Data is organized in equal intervals. A histogram is a type of graphical representation that organizes a group of data points into a specified range. The data is portrayed via bars of different heights, where each bar groups numbers into ranges. These bars touch each other where the height of each bar corresponds to its frequency of data points. Unlike bar charts, histograms do not display data in separate categories, but as continuous data grouped into ranges, hence they are arranged in equal intervals.

Mme Q spent more time answering emails from students by 10 minutes

Step-by-step explanation:

Here we have

Time spent by Mme Q in answering mails on Friday given by

5/6 Hour = 50 minutes and

7/12 Hour = 35 minutes

Total time spent on Friday = 85 Minutes or

5/6 + 7/12 = 17/12 Hours

Time spent by Mme F in answering mails on Friday given by

1/2 Hour = 30 minutes and

3/4 Hour = 45 minutes

Total time spent on Friday by Mme F = 75 Minutes or

1/2 + 3/4 = 5/4 Hours

Therefore, Mme Q spent more time answering emails from students by 85 - 75 = 10 minutes.

Answer:

1689 MAE

Step-by-step explanation:

The measure of the arc AE is 120°

We can solve this with the Intersecting Secant Angles Theorem.

That theorem says that:

∠ACE = (mAE - mBD)/2

so

36 = (mAE - 48)/2

so,

mAE - 48 = 72 => mAE = 72 + 48 = 120°

therefore, the measure of the arc AE is 120°

The amount of money Lani and her friends can earn walking different dogs depends on a number of factors, including:

Here is an example of how to calculate the potential earnings for Lani and her friends:

Number of dogs walked per day/week: Let's say Lani and her friends walk 5 dogs per day, 5 days per week.

Length of each walk: Let's say each walk is 30 minutes long.

Rates charged per dog/walk: Let's say they charge $20 per dog per walk.

Demand for dog walking services: Let's say there is a high demand for dog walking services in their area.

Based on these assumptions, Lani and her friends could earn up to $250 per day and $1,250 per week walking dogs

Of course, these are just estimates. The actual amount of money they earn will depend on the factors listed above.

Answer: [tex]BC=14.8[/tex]

Step-by-step explanation:

By definition, an Isosceles triangle has two equal sides and its opposite angles are congruent.

Observe the figure attached, where the isosceles triangle is divided into two equal right triangles.

So, in this case you need to use the following Trigonometric Identity:

[tex]sin\alpha =\frac{opposite}{hypotenuse}[/tex]

In this case, you can identify that:

[tex]\alpha =\angle BAD=\angle CAD=18\°\\\\opposite=BD=CD=x\\\\hypotenuse=AB=AC=24[/tex]

Substituting values, and solving for "x", you get:

[tex]sin(18\°)=\frac{x}{24}\\\\24*sin(18\°)=x\\\\x=7.416[/tex]

Therefore, the length of BC rounded to nearest tenth, is:

[tex]BC=2(7.416)=14.8[/tex]

Step-by-step explanation:

A linear equation looks like any other equation. It is made up of two expressions set equal to each other. A linear equation is special because: It has one or two variables. No variable in a linear equation is raised to a power greater than 1 or used as the denominator of a fraction

The given equation y = x² - 1 is not a linear equation.

Linear equations are algebraic equations that have only one constant and are only of the first degree.

We know that linear equations are of the only first-order(linear) term, but since the given equation has the second-order(linear) term.

Hence, the given equation y = x² - 1 is not a linear equation.

Answer:

The quotient of the division will become a factor in a multiplication fact.

Step-by-step explanation:

In division there is a relationship between the dividend, divisor, quotient and remainder. The number which we divide is referred to as the dividend. The number by which we divide is called the divisor. The result obtained is known as the quotient. The number left over is called the remainder.

The dividend, divisor, quotient and remainder will help us to verify the answer of division. Add remainder (if there is any) with the product of divisor and quotient. The sum we get should be equal to the dividend.

The quotient of the division will become a factor in a multiplication fact.

For instance,

18 ÷ 3= 6

Where 3 is the divisor, 6 the quotient and 18 the dividend

3 × 6= 18

The quotient of the division 6 is a factor in the multiplication.

Step-by-step explanation:

To find this, we need to know what one-third of 24 boxes are; we'd then do 24 divided by 3, which is equal to 8. One-third of them were grape so we know 8 are grape. Cranberry makes up the other two-thirds; two-thirds is equal to one-third times 2. 8 (one-third) times 2 is 16, giving our answer of 16 cranberry.

To calculate the density of pixels on the television, divide the total number of pixels by the actual area of the television screen. Use the scale drawing to find the actual area of the television screen. In this case, the density of pixels on the television is 5.8 pixels per square unit.

The density of pixels on the television can be calculated by dividing the total number of pixels by the total area of the television screen. In this case, the total number of pixels is given as 58,000. To find the area of the television screen, we need to use the scale drawing. Let's say the scale factor is 1:100. If we represent the actual area of the television screen as A, and the area shown on the scale drawing as D, we can set up the equation A/D = 1/100. Rearranging the equation, we have A = D * 100. Now we can substitute the value of D, which is the area shown on the scale drawing, into the equation. So, if the area shown on the scale drawing is 100 square units, the actual area of the television screen would be 100 * 100 = 10,000 square units. Finally, we can calculate the density of pixels by dividing the total number of pixels (58,000) by the actual area of the television screen (10,000). The density of pixels on the television is therefore 5.8 pixels per square unit.

In this line equation y=3x+9, you find the values of x and y by plugging in different x-values and calculate corresponding y-values. These (x,y) pairs are points on the line which can be represented on the graph.

The subject of this question is Mathematics, specifically equations of a line. Looking at the initial line equation, the form appears to be y = mx + b, where m is the slope and b is the y-intercept. Based on the given information, m is set to 3 and b to 9.

To find values of x and y, you plug different x-values into the equation and solve for y. For example, if x=1, y would be 3×1+9=12. Thus, for x=1, y=12. This applies on this line for all different x-values.

Remember: different values of x will correspond to different values of y. This relation can be represented graphically by plotting these (x,y) pairs on a graph, and drawing a line through them.
