which graph shows a polynomial function with a positive leading coefficient?

Answer:

Yes

Step-by-step explanation:

The pair of congruent angles needs to be included between the congruent sides. Since this is not the case, more information is needed.

The correct response is yes, the additional information is needed to show that ΔDEF is congruent to ΔGHJ by SAS congruency rule is whether the sides DE and GH, are congruent

The SAS (Side-Angle-Side) congruency postulate states that two triangles are congruent if two sides and the included angle of one triangle are congruent to two sides and the included angle of the other triangle.

The specified information for each triangle, starting from the indicated angle, and calling the sides in a clockwise direction, we get;

∠E, side EF and side DF in triangle ΔDEF are congruent to angle ∠H, side HJ, and side GJ

Therefore, the information from the diagram in the question are a nonincluded angle and two sides, SSA, which is not a condition for congruency.

The additional information needed to prove ΔDEF is congruent to ΔGHJ, by SAS are the sides DE and GH, which makes the angle ∠E and ∠H included angles.

Therefore, additional information is required;

The standard deviation is decreases then the graph of the normal z - score curve is increases.

A standard deviation (or σ) is a measure of how dispersed the data is in relation to the mean. Low standard deviation means data are clustered around the mean, and high standard deviation indicates data are more spread out.

The standard deviation is calculated as the square root of variance by determining each data point's deviation relative to the mean. If the data points are further from the mean, there is a higher deviation within the data set; thus, the more spread out the data, the higher the standard deviation.

In mathematics, the Z score is used to quantify how many standard deviations the raw score deviates from or approaches the mean. Giving the z score are:

z = (x - μ ) / σ

Where,

x = raw score

μ = mean

σ = standard deviation

For a sample size,

z =  (x - μ ) / σ / [tex]\sqrt{n}[/tex]

The z score affects the area under the curve. The area under the curve increases as the z score increases and decreases as the z score decreases.

The standard deviation has an inverse relationship with the area under the curve (z score). The z score drops as the standard deviation rises, diminishing the area under the curve.

The area under the curve grows as the standard deviation is reduced because the z score increases.

Therefore,

The standard deviation is decreases then the graph of the normal z - score curve is increases.

kiloliter

One thousand liters is called a kiloliter. A kiloliter is equal to 264.172 gallons. One liter is equal to 0.264172, so if you want to find how many gallons there are in 1 kiloliter, just multiply 0.264172 by 1000

Answer:

1000 liters  

Step-by-step explanation:

By solving a linear equation we will see that the value of x is 10.

Remember that for any triangle, the sum of all internal angles is always equal to 180°.

Here only look at triangle BCD, we know that:

m∠DBC = m∠ABC = 3x

m∠BCD = m∠ACB + m∠ABD = 2x + 65°

m∠ADC = 65°

Now we can write the linear equation as:

3x + 2x + 65° + 65° = 180°

5x + 130° = 180°

5x = 180° - 130°

5x = 50°

x = 50°/5 = 10°

The value of x is 10.

The sum of the area of the rectangle has an area of 5x + 22 ft²rectangle b has an area of 8x - 2  ft² is  13x + 20  ft².

An enclosed 2-D shape called a rectangle has four sides, four corners, and four right angles (90°). A rectangle has equal and parallel, opposite sides. Since a rectangle is a two-dimensional form, it has two dimensions: length and width. The rectangle's longer side is its length, while its shorter side is its breadth.

Given:

The area of a rectangle, A = 5x+22 ft²,

The area of a rectangle, B = 8x-2 ft²,

Calculate the sum of the areas as shown below,

A + B = 5x + 22 + 8x - 2

A + B = 13x + 20  ft²

Step-by-step explanation:

To determine whether 101 ounces is a reasonable estimate for the weight of 25 letters that each weigh between 3.92 ounces and 4.2 ounces, we need to calculate the range of possible weights for the letters.

The minimum weight for the letters is 25 * 3.92 ounces = 98 ounces. The maximum weight for the letters is 25 * 4.2 ounces = 105 ounces. Therefore, the range of possible weights for the letters is 98-105 ounces.

Since 101 ounces falls within this range, it is a reasonable estimate for the weight of the letters.
