Answer:

c. The shoe retailer is gathering raw data because he is recording shoe sizes and styles by himself.

Step-by-step explanation:

He records this data for an entire year by keeping track of his customers' purchases.

His customer's purchases will be from his shop and no one elses from the neighbours or of other company.

The only way to keep record of his customers' purchases is from his shop.

Option a is incorrect because he wants to check the drive force of his shop not other shops.

Option b is also incorrect because the items bought indicate the purchases not the preference told.

Option d is also incorrect becuase nearby companies wil have their own styles and sizes collection.

Answer:

a.) The classes are successful

b.) The classes might not be successful.

c.) Type 11 error

d.) Yes

E.) No

Step-by-step explanation:

C.)

This means that we failed to reject H0 when it is actually FALSE and in fact the classes are successful , that means mean μ > 100, that is: null hypothesis is False.

D.)

Type 1 error occurs when we incorrectly reject H0 ; that is we rejected H0, when it is true

Here, H0, means the classes aren't successful, hence, incorrectly rejecting H0 means we have committed a type 1 error

E.)

Type 11 error means failing to reject H0

;

Here, H0, means the classes aren't successful,

Hence, if we fail to reject H0 in this scenario, we are right, hence, there is no possibility of making a type 11 error in this scenario

Answer:

68.7

Step-by-step explanation:

Answer:

m∠G ≈ 41°

Step-by-step explanation:

The value of angle G will be approximately 41.4 °

The square of a side of a plane triangle equals the sum of the squares of the remaining sides minus twice the product of those sides and the cosine of the angle between them.

c² = a² + b² - 2ab cos[tex]\rm \gamma[/tex]

Here in triangle EFG ,

To find angle G

a = 12

b=10

c=8

8² = 12² + 10² - 2*12*10 cos[tex]\rm \gamma[/tex]

64 = 144 + 100 -240 cos    [tex]\rm \gamma[/tex]

64-244 = -240 cos[tex]\rm \gamma[/tex]

-180 = -240 cos[tex]\rm \gamma[/tex]

180/240 = cos [tex]\rm \gamma[/tex]

3/4 = cos [tex]\rm \gamma[/tex]

Therefore angle G will be approximately 41.4 °

Answer:

Step-by-step explanation:

Answer: 352

Step-by-step explanation:

Answer:

x = 11

Step-by-step explanation:

Given the expression;

5x+2y=67 ...1

x=3y−7 ....2

Substitute 2 into 1

5(3y-7)+2y = 67

15y - 35 + 2y = 67

17y = 67+35

17y = 102

y = 102/17

y =6

Recall that x = 3y - 7

x = 3(6) - 7

x = 18 - 7

x = 11

Hence the value of x is 11

Answer:

the smallest circle one

center => (0,1)

radius = √3 = 1.73

Graph C  best represents the equation x² + (y-1)²=3². The given equation is compared by the standard equation to form a graph.

If a circle O has a radius of r units and its center is at (h, k) in the coordinate plane, then its equation is:

(x-h)^2 + (y-k)^2 = r^2

The given data equation is;

Step-by-step explanation:

This is a familiar conversion problem:

[tex]3.3 \times {10}^{2} lightyears \times \frac{5.9 \times {10}^{12} miles}{1 \: lightyear} [/tex]

[tex] = 1.95 \times {10}^{15} \: miles[/tex]

Answer:

see below

Step-by-step explanation:

3.3 × 10^2  light years

one light year is 5.9 × 10^12 miles

you need to multiple these two values

3.3 × 10^2  light years  ×  5.9 × 10^12 miles/light year =

=     (3.3 × 5.9) × 10^2 × 10^12

=     19.47 × 10^(2 + 12)

=     1.947 × 10^1 × 10^14

=     1.947 × 10^15 miles

Given:

The equation is:

[tex]192=6000\left(0.02\left(\dfrac{8}{5}-4y\right)+0.08y\right)[/tex]

To find:

The value of y.

Solution:

We have,

[tex]192=6000\left(0.02\left(\dfrac{8}{5}-4y\right)+0.08y\right)[/tex]

On simplification, we get

[tex]192=6000\left(0.02\times 1.6-0.02\times 4y+0.08y\right)[/tex]

[tex]192=6000\left(0.032-0.08y+0.08y\right)[/tex]

[tex]192=6000\left(0.032\right)[/tex]

[tex]192=192[/tex]

Since LHS=RHS and the equation is free from the variable y, therefore the given equation is true for all real values of y.

Hence, all real values of y are solutions.

Answer:

[tex]\huge\boxed{\sf h = 26.684\ feet}[/tex]

Step-by-step explanation:

See the attached file along with the solution.

Let the height be h,

base of triangle 1 be x

base of triangle 2 be 100 - x

Using the following trigonometry for both the triangles.

[tex]\displaystyle tan (\theta) = \frac{opposite}{adjacent}[/tex]

For triangle 1:

tan 20 = h / x    ---------------------(1)

For triangle 2:

tan 45 = h / 100 - x  -----------------(2)

Taking Eq. (1)

tan 20 = h / x

Multiply both sides by x

tan 20 * x = h

h = tan (20) * x

h = 0.36397x   -----------------------(3)

Put Eq. (3) in (2)

tan (45) = 0.36397x / 100-x

1 = 0.36397 x / 100 - x

Multiply both sides by 100 - x

100 - x = 0.36397 x

Add x to both sides

100 = 0.36397 x + x

100 = 1.36397 x

Divide both sides by 1.36397

100 / 1.36397 = x

73.315 = x

x = 73.315 feet

Now, Finding h (height):

tan 20 = h / x (Eq. (1))

h = tan (20) * x

h = 0.36397 * 73.315

h = 26.684 feet

Answer:

364 ft

Step-by-step explanation:

26x14=364

Since the shape is a square pyramid, the base would be 14 by 14. The area of one triangle would be 10 times 14 times 1/2 = 70. 70 times 4 = 280. 14 times 14 = 196

196 + 280 = 476

Final answer = 476
