Answer: Paired t interval for μdiff

Step-by-step explanation:

The confidence interval suitable for analysing the data described in the scenario above is the paired t test which is employed when there are two different sets of measured reading or observation for each subject. In the scenario above, the subjects are of of the different planters employed whereby the pair of measurement are the weight of tomatoes obtained for each of the two different fertilizer types applied to each of the two plants in a planter. With these data, we can measure the difference in the effectiveness of each of the store brand and homegrown compost.

Answer:

27.84 m² , 42.48 m²

Step-by-step explanation:

The area (A) of a triangle is calculated as

A = [tex]\frac{1}{2}[/tex] bh ( b is the base and h the perpendicular height )

Shape A

has b = 9.6 and h = 5.8, then

A = 0.5 × 9.6 × 5.8 = 27.84 m²

Shape B

has b = 11.8 and h = 7.2 , then

A = 0.5 × 11.8 × 7.2 = 42.48 m²

Answer:

Shape A = 55.68

Shape B = 79.2

Step-by-step explanation:

Shape A work : [tex]9.6[/tex] x [tex]5.8[/tex] = 55.68

Shape b work :  11 x 7.2 = 79.2

Answer:

x = 80 / 79 [improper fraction]

x = 1 ¹⁄₇₉ [mixed fraction]

x = 1 + [tex] 0.\overline{0126582278481} [/tex]

[decimal]

x ≈ 1.01 [decimal to nearest hundredth]

Step-by-step explanation:

10.3x + 4.5x = 15

(10.3 + 4.5)x = 16

(15.8)x = 16

(15.8)x / 15.8 = 16 / 15.8

x = 16 / 15.8

x = (16) / (15 + ⁸⁄₁₀)

x = (16) / (15 + ⅘)

x = (16) / (15 ⅘)

x = (16) / (79 / 5)

x = (16) × (5 / 79)

x = 80 / 79

x = 1 ¹⁄₇₉

x = 1 + ¹⁄₇₉

x = 1 + [tex] 0.\overline{0126582278481} [/tex]

x ≈ 1.01

Answer:

1 5/6 = 11/6

7 1/3 = 22/3

11/6 + 22/3 = 11/6 + 44/6 = 55/6 ≈ 9.16

1 5/6 = 11/6

11/6 - 1/10

55/30 - 3/30 = 52/30 ≈ 1.73

9.16 x 1.73 = 15.8468

So, 15.8468 is the result.

Answer:

The image does not have four right angles because translations preserve angle measures.

Answer:

either 17.5 or 10

Step-by-step explanation:

if you minus 40 3 times you get 17.5

take 3/2 - 1/4 over to the right side of the equal sign( and then the signs change; the '+' & '-' )

then 1/2x + 3/2x =2x

and 5 -3/2 + 1/4 = 15/4

to get x alone you divide both sides by 2.

Answer:

2.598cm

Step-by-step explanation:

Area of a triangle =1/2 * base * Height

Given

ARea = 39.6cm^2

Base= 12in = 2.54 * 12

Base = 30.48cm

Required

Height

Substitute

39.6 = 1/2 * 30.48 * H

39.6 = 15.24 * H

H = 39.6/15.24

H = 2.598cm

Hence the height of the triangle is 2.598cm

Answer:

10.8 meters

Step-by-step explanation:

This situation forms a right triangle, where the length of the kite string is the hypotenuse, the distance from where it is held is the long leg, and the height is the short leg.

Use the pythagorean theorem to solve for c, the length of the kite string.

a² + b² = c²

6² + 9² = c²

36 + 81 = c²

117 = c²

10.8 = c

So, the length of the kite string is 10.8 meters

Answer:

3.43 hours

Step-by-step explanation:

A castle has to be guarded 24 hours a day. 7 knights are ordered to split each day guard duty equally. How long will each knight spend on guard duty in one day?

From the above question:

7 knights = 24 hours

1 knight = x hours

Cross Multiply

7 knights × x hours = 1 knight × 24 hours

x hours = 1 knight × 24 hours/ 7 knights

x hours = 3.4285714286 hours

Approximately = 3.43 hours

Therefore, each knight would spend 3.43 hours on guard duty in one day

The missing value should be in the table is 750 and 1250.

1                     250

2                    500

3                     750

4                    1000

5                    1250

Since we can see that there is the gap of 250 in each words

like

= 250 + 250

= 500

So

= 500 + 250

= 750

And, so on

The sequence 5, 8, 13, 21, is option D: neither an arithmetic nor a geometric sequence.

What is a sequence?

A sequence is an enumerated group of items in mathematics where repetitions are permitted and order is important. Similar to a set, it has members (also called elements, or terms). The length of the series is the number of elements (potentially infinite).

In an arithmetic sequence, each term is obtained by adding a fixed constant to the preceding term.

In a geometric sequence, each term is obtained by multiplying the preceding term by a fixed constant.

For example, an arithmetic sequence with a first term of 2 and a common difference of 3 would be -

2, 5, 8, 11, 14, ...

And a geometric sequence with a first term of 2 and a common ratio of 3 would be -

2, 6, 18, 54, 162, ...

In the given sequence 5, 8, 13, 21, it can be seen that the difference between successive terms is not constant (i.e., 3-5 = -2, 13-8 = 5, 21-13 = 8).

Therefore, this is not an arithmetic sequence.

Similarly, the ratio between successive terms is not constant, so this is not a geometric sequence either.

Therefore, this sequence is an example of a more general type of sequence that does not follow a simple pattern, and is often referred to as a non-linear sequence.
