Answer:

It’s skewed left

Step-by-step explanation:

The main mass of the graph is on the left. Follow the shape of the graph to find this

To determine if a histogram is symmetric or skewed, we assess the relative positions of the mean, median, and mode. A symmetric distribution has these three values approximately equal and the histogram's halves mirror each other. A right-skewed histogram has a tail extending right, whereas a left-skewed histogram's tail extends left.

When analyzing whether a histogram is symmetric, skewed right, or skewed left, certain aspects of the distribution of data are considered. Symmetry in a histogram indicates that if a vertical line were drawn at some midpoint, the left and right sides would be mirror images. In a symmetric distribution, the mean, median, and mode are usually equivalent or very close to each other. To determine skewness, we look at the arrangement of these three measures: for a skew to the right, the mode is often less than the median, which is less than the mean. Conversely, a distribution skewed to the left typically has the mean less than the median, which is less than the mode.

A histogram for a right-skewed distribution will often show a tail extending to the right, indicating that larger numbers in the dataset are more spread out. On the other hand, a histogram with a left-skewed distribution will show a tail that extends to the left, which implies that the lower numbers are more spread out.

[tex]5^{x}=7[/tex]

step 3

Apply ln both sides

[tex]ln(5^{x})=ln(7)[/tex]

step 4

[tex]xln(5)=ln(7)[/tex]

step 5

Answer:

x = -3 and y = -2

Step-by-step explanation:

It is given that,

-7x + 6y = 9     ----(1)

-2x - 5y = 16    -------(2)

To find the solution of given equations

eq(1) * 2 ⇒

-14x + 12y = 18 ------(3)

eq(2) * 7 ⇒

-14x - 35y = 112   ---(4)

eq (3) - eq(4) ⇒

-14x + 12y = 18 ------(3)

-14x - 35y = 112  ---(4)

    0   4y = -94

y = 94/(-47) = -2

Substitute the value of y in eq (2)

-2x - 5y = 16    -------(2)

-2x - 5*-2 = 16

-2x +10 = 16

-2x = 6

x = 6/-2 = -3

Therefore x = -3 and y = -2

Answer:

[tex]x=-3\\\\y=-2[/tex]

Step-by-step explanation:

Given the system of equations [tex]\left \{ {{-7x+6y=9} \atop {-2x-5y=16}} \right.[/tex], you can use the Elimination Method to solve it.

You can multiply the first equation by -2 and the second equation by 7, then add both equations and solve for the variable "y":

[tex]\left \{ {{14x-12y=-18} \atop {-14x-35y=112}} \right.\\...........................\\-47y=94\\\\y=\frac{94}{-47}\\\\y=-2[/tex]

Substitute the value of "y" into any original equations and solve for the variable "x". Then:

[tex]-7x+6y=9\\\\-7x+6(-2)=9\\\\-7x-12=9\\\\-7x=9+12\\\\x=\frac{21}{-7}\\\\x=-3[/tex]

Answer:

A rectangular equation, or an equation in rectangular form is an equation composed of variables like x and y which can be graphed on a regular Cartesian plane.

Parametric equations are a set of equations that express a set of quantities as explicit functions of a number of independent variables, known as "parameters." For example, while the equation of a circle in Cartesian coordinates can be given by r^2=x^2+y^2, one set of parametric equations for the circle are given by

x=r cost

y=r sin

Note that parametric representations are generally nonunique, so the same quantities may be expressed by a number of different parameterizations. A single parameter is usually represented with the parameter t, while the symbols  u and v are commonly used for parametric equations in two parameters.Parametric equations provide a convenient way to represent curves and surfaces, as implemented, for example, in the Wolfram Language commands ParametricPlot[{x, y}, {t, t1, t2}] and ParametricPlot3D[{x, y, z}, {u, u1, u2}, {v, v1, v2}]. Unsurprisingly, curves and surfaces obtained by way of parametric equation representations are known as parametric curves and parametric surfaces, respectively.

Answer:

6 inches

Step-by-step explanation:

3392.92 cubic inches of liquid distributed in 30 spheres would give each sphere's volume to be:

[tex]\frac{3392.92}{30}=113.1[/tex]

Now we equate 113.1 to the formula for volume of a sphere and solve for r:

[tex]\frac{4}{3}\pi r^3=113.1\\r^3=\frac{113.1}{\frac{4\pi}{3}}\\r^3=27\\r=\sqrt[3]{27} =3[/tex]

The radius of each of those spheres is 3

We know diameter is twice the radius , so diameter would be 3 * 2 = 6 inches

Answer: second option.

Step-by-step explanation:

When two parallel lines are intersected by a third line (which is called "Transversal"), the angles that are of the same side of the transversal (but one located in interior and the other one located in the exterior), are known as "Corresponding angles".

Corresponding angles are congruent.

You can observe that the angle 2 and the angle 6 are Corresponding angles. Therefore, the missing justification is: "Corresponding angles formed by a transversal on parallel lines are congruent."

Answer:

Corresponding angles formed by a transversal on parallel lines are congruent.

so if we use that many ingredients to make a whole three thirds, how much will it be to make only two thirds of it?  well, is simply their product, so we'll simply multiply each ingredient amount by 2/3.

Answer:

Total interest will $1800 after 5 years.

Step-by-step explanation:

It is given that the principle amount is $6000.

Rate of interest rate is 6% per annum.

Total interest is $1800.

Formula for simple interest is

[tex]I=\frac{P\times r\times t}{100}[/tex]

Where, P is principle, r is rate of interest in percent and t is time in years.

Substitute P=6000, r=6 and I=1800 in the above formula.

[tex]1800=\frac{6000\times 6\times t}{100}[/tex]

[tex]1800=\frac{36000t}{100}[/tex]

[tex]1800=360t[/tex]

Divide both sides by 360.

[tex]\frac{1800}{360}=t[/tex]

[tex]5=t[/tex]

Therefore the total interest will $1800 after 5 years.

Step-by-step explanation:

Let h = number of hours the Sun was up today.

There are 24 hours in one day.

So, we are looking at the fraction h/24.

Answer: The fraction of the time the Sun was up today.

The function that multiplies the number of hours the Sun was up (h) by 60 represents the number of minutes the Sun was up today.

If h represents the number of hours the Sun was up today, to calculate the number of minutes the Sun was up, we would multiply h by 60, since there are 60 minutes in an hour. Therefore, the function that multiplies h by 60 will give us the number of minutes the Sun was up today. On the contrary, to find the number of hours the Sun was down today, we would typically take the total number of hours in a day, which is 24, and subtract h from it. To represent the fraction of the time the Sun was up today, we would use the ratio of h to 24, since there are 24 hours in a whole day. Thus, the correct quantity represented by the function when h is multiplied by 60 is the number of minutes the Sun was up today.

The expression that represents the height of the rectangular prism is 3x + (10 / (2x - 4)) found by dividing the given volume expression by the base area expression.

To find the expression that represents the height of the rectangular prism, we need to rearrange the formula for the volume of a prism, which is Volume = Base Area x Height. Given the volume of the rectangular prism as 6x^2
- 2x + 8 and the base area as 2x - 4, we divide the volume by the base area to find the height:

Height = Volume / Base Area

Height = (6x^2 - 2x + 8) / (2x - 4)

This simplifies to:

Height = 3x + (10 / (2x - 4))

Therefore, the expression that represents the height is 3x + (10 / (2x - 4)).

Answer:

[tex]y=500(1.05)^x[/tex]

Step-by-step explanation:

The standard form for an exponential equation is

[tex]y=a(b)^x[/tex]

We have 2 unknowns, a and b, but that's all good because we have 2 (x, y) coordinates we can utilize in order to find a and b.  In our coordinate pair, x is the number of years gone by and y is the value after that number of years.  The problem tells us that an item was purchased for $500.  That translates to "before any time has gone by, the initial value of the item is $500".  In other words, with x being time, no time has gone by, so x = 0.  When x = 0, y = 500.  (0, 500).  Do the same for the next set of numbers.  When x = 2 years gone by, the value is $551.25, so the coordinate is (2, 551.25).  Now we use them to find a.  Use the first coordinate:

[tex]500=a(b)^0[/tex]

Anything raised to the 0 power = 1, therefore:

[tex]500 = a(1)[/tex] and a = 500.

Now onto the next coordinate point using the a value we just found:

[tex]551.25 = 500(b)^2[/tex]

Divide both sides by 500 to get

[tex]1.1025=b^2[/tex]

so b = 1.05.

Now we have the values for a and b, so we fill in:

[tex]y = 500(1.05)^x[/tex]
