For this case we have the following expression:
$\frac{7^6}{7^2}$
By power properties we can rewrite the expression in the following way:
$7^{6-2}$
Then, simplifying the expression we have:
$7^{4}$
Answer:
The simplified expression is given by:
$7^{4}$

The null and alternative hypotheses are given. Determine whether the hypothesis test is left-tailed, right-tailed, or two-tailed

NNADVOKAT [17]

Correct clear question is;

The null and alternative hypotheses are given. Determine whether the hypothesis test is left-tailed, right-tailed, or two-tailed. What parameter is being tested? H_0: μ = 5 H_1: μ ≠ 5

Is the hypothesis test left-tailed, right tailed, or two tailed? A Left tailed B Right tailed C Two tailed

What parameter is being used? A population proportion B population mean C standard deviation

Answer:

A) C - Two tailed hypothesis

B) B - Population mean

Step-by-step explanation:

We are given the hypotheses to be;. Null Hypothesis; H_0: μ = 5

Alternative hypothesis; H_1: μ ≠ 5

From the alternative hypothesis, we can see that the critical area of distribution of the parameter being tested could either be less than 5 or greater than 5 due to the not equal to sign. This means it could either be left tailed or right tailed. Thus, it is a two tailed hypothesis.

From the hypothesis, we see that the symbol μ is being used.

In statistics, μ is generally used as a symbol to denote population mean.

Thus, parameter being used/tested is population mean

What do all of these polygons have in common? There are four polygons labeled A, B, C and D. Each polygon has one pair of parall

mafiozo [28]

The thing that all these polygons have in common is B. Each appears to have one pair of parallel sides.

<h3>What is a polygon?</h3>

A polygon is a plane figure characterized by a finite number of straight line segments joined to form a closed polygonal chain in geometry. A polygon is defined as a bounded plane region, a bounding circuit, or both. A polygonal circuit's segments are known as its edges or sides.

A polygon is a two-dimensional closed object with straight sides that is flat or plane. It doesn't have any curved edges. The vertices are the spots where two sides intersect.

A geometric figure has parallel sides if the distance between them does not change and the sides do not meet or cross. Parallel sides of a shape are opposing, or across from each other, and would not intersect if extended infinitely beyond the shape's boundaries.

Parallelogram, rectangles, squares, trapezoids, hexagon, and octagon are examples of shapes with parallel sides.

In their last game, the school football team scored an equal number of points in each of the first three quarters, then 14points

Ksenya-84 [330]

Answer:

10 points

Step-by-step explanation:

Points scored in each of the first 3 quarter = x

Total points scored in the first 3 quarter = x + x + x

= 3x

Points scored in the fourth quarter = 14

Total points scored = 44 point

Total points scored = Total points scored in the first 3 quarter + Points scored in the fourth quarter

44 = 3x + 14

Subtract 14 from both sides

44 = 3x + 14

44 - 14 = 3x + 14 - 14

30 = 3x

Divide both sides by 3

x = 30/3

= 10

x = 10 points

Points scored in each of the first 3 quarter = x = 10 points

The school football team scored 10 points points in the first quarter

Delia has 3 5/8 yards of ribbon. About how many 1/4 yard-long pieces can she cut?

grin007 [14]

Answer: There are 14 long pieces she can cut.

Step-by-step explanation:

Since we have given that

Length of yards of ribbon is given by

$3\frac{5}{8}\ yards\\\\=\frac{29}{8}\ yards$

Length of yards of ribbon pieces need to be cut is given by

$\frac{1}{4}\ yards$

Number of yards is given by

$\frac{\frac{29}{8}}{\frac{1}{8}}\\\\=\frac{29}{2}\\\\=14.5\\\\=14$

Hence, there are 14 long pieces she can cut.
