Answer:

x = 6 (brainliest..?)

Step-by-step explanation:

x² = 4(4 + 5)

x² = 36

x = 6

Answer:

30 cm²

Step-by-step explanation:

To find the area of a triangle, multiply the base and the height, then, divide the product by 2.

In this case, the base is 6 and the height is 10.

6 x 10 = 60

The product is 60.

60 / 2 = 30

Therefore, the area of this triangle is 30 cm².

Answer:

30

Step-by-step explanation:

Formula for area of a triangle: [tex]A=\frac{bh}{2}[/tex]

where b = base length and h = height

The triangle shown has a base length of 6 cm and a height of 10 cm

Using this information we plug in the values into the formula

So...

[tex]A=\frac{10*6}{2} \\10*6=60 \\\frac{60}{2} =30[/tex]

Hence, the area of the triangle is 30 square centimeters.

Answer:

We accept H₀. We don´t have enough evidence to support the difference between the two means

Step-by-step explanation:

Group 1 : Comunity College

Sample:

size  :   n₁  = 54

Sample mean    x₁  = 947

Sample standard deviation     s₁ = 254

Group 2 : Local University

Sample

size  :  n₂  =  66

Sample mean :  x₂  = 1011

Sample standard deviation    s₂  =  87

Significance level  α  = 0,05      α  =  5 %      CI = 95 %

Both samples are with n> 30 so we can use z table for the test

from z-table we find  z(c)  =  1,96

The problem statement establishes to run a hypothesis test to determine if the means are statistically the same  ( or different) then we use two-tail-test

Hypothesis Test

Null Hypothesis                        H₀             x₁   -  x₂  = 0 or    x₁  = x₂

Alternative hypothesis             Hₐ             x₁  -  x₂  ≠  0  or    x₁ ≠ x₂

To calculate

z(s)  =  (  x₁   -  x₂  ) / √ s₁²/n₁  + s₂²/n₂ )

z(s)  =  947  -  1011 / √  (254)²/54   +  (87)² / 66

z(s) = -  64  /√ 1194,74  +  114,68

z(s) =  - 64  / 36,185

z(s) =  - 1,77

Comparing modules of  |z(c)|  and |z(s)|

z(s) < z(c)

Then z(s) is in the acceptance region we accept H₀ . There is not enough evidence to support differences in the means of the two groups

The store will make money for each option/event. For the first option, the store will earn extra $72. For the second option, the store will earn extra $14.4.

Step-by-step explanation:

120 x 1.6 = 192

192 x 0.7 = 134.4

For problem 1, the answer is $192

For problem 2, the answer is $134.4

The store will make money for each option/event.

192-120=72

134.4-120=14.4

Answer:

Option D

S=8/1-.2

Step-by-step explanation:

Edg

The sum of the sequence will be S = 8 / (1 – 0.2). Then the correct option is D.

Let a be the first term and r be the common ratio. Then the sum of the geometric series will be

S = a / (1 – r) if r < 1

S = a / (r – 1) if r > 1

The sum of [tex]\rm \Sigma_{n = 1}^{\infty} 8(0.2)^{n - 1}[/tex].

Then the first term of the geometric sequence will be 8.

And the common difference between the successive terms will be 0.2.

The common ratio less than one, then the formula for the sum will be given as

S = a / (1 – r) if r < 1

Then the sum of the sequence till infinity will be

S = 8 / (1 – 0.2)

S = 8 / 0.8

S = 10

Thus, the sum of the sequence will be S = 8 / (1 – 0.2).

Then the correct option is D.

Answer: (9y^4*x^6)^2

Step-by-step explanation: First you take the square root of 81, which is 9. Next, you divide 8 and 12 by 2. Lastly, you multiply everything together, and you get a final answer of (9y^4*x^6)^2. Do you do RSM?

Answers :

you will nees to use pythagorean theorem a^2 + b^2 = c^2

the a and b values will be 12 and 5 feet. So just plug them in and solve for c

12^2 + 5^2 = c^2

144 + 25 = c^2

169 = c^2 square root both sides

13 = c

so the ladder has a length of 13 feet.

Answer:

63

Step-by-step explanation:

Given:

Length of the rectangular prism = 13 units.

Width of the rectangular prism = 6 units.

Height of the rectangular prism = 4 units.

To find:

The volume of the rectangular prism.

Solution:

We know that the volume of the rectangular prism is:

[tex]V=l\times b\times h[/tex]

Where, l is length, b is breadth or width and h is the height of the rectangular prism.

Putting [tex]l=13,b=6,h=4[/tex] in the above formula, we get

[tex]V=13\times 6\times 4[/tex]

[tex]V=312[/tex]

Therefore, the volume of the given rectangular prism is 312 cubic units.
