A castle has to be guarded 24 hours a day. 7 nights are ordered to split each day guard duty equally. How long will each night spend on guard duty in one day?
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 area of a right triangle is 39.6cm2 , and the base of the triangle is 12in . Which of the following values is the height of the triangle?
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:
Step-by-step explanation:
y = ax² + bx + c
Plug in the three given points, then solve for a, b, c
(-3,0): 0 = 9a - 3b + c
(4,0): 0 = 16a + 4a + c
(0,-12): -12 = c
9a - 3b = 12
3a - b = 4
16a + 4b = 12
4a + b = 3
a = 1
b = -1
y = x² - x - 12

Anne claims that a store-brand fertilizer works better than homemade compost as a soil enhancement when growing tomatoes. To test her theory, she plants two tomato plants in each of five planters. One plant in each planter is grown in soil with storebrand fertilizer and the other plant is grown in soil with homemade compost, with the choice of soil determined at random. In three months, she will harvest and weigh the tomatoes from each plant. What is the correct confidence interval Anne should use to analyze these data
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.

How did the 5 become 15/4... kinda confuse can anybody help????????????
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.
i hope this helps

Which diagram matches the equation or description.
I believe the answer to this diagram should be Diagram B
estimate the product then find the product
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.
I hope this is helpful. :)

What kind of sequence is this?
5, 8, 13, 21,
arithmetic
geometric
both
neither
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.

• How much do customers have to spend in order to raise $1,000 for the pet rescue program? Amount Spent (dollars) 120 Amount Donated (dollars) 1000
Complete question :
a pet store had a special offer this weekend. for every $120 that customers spend, $3 is donated to a pet rescue program. How much do customers have to spend in order to raise $1000 for the pet rescue program?
Answer:
$40000
Step-by-step explanation:
Offer :
For every $120 spent ; $3 is donated
In other to raise $1000 ; $x would have to be spent ; we can obtain the value of x using cross multiplication ;
$120 = $3
$x = $1000
Cross multiply
$(120 * 1000) = $3 * x
$120000 = $3x
x = 120000 / 3
x = 40,000
Hence, in other to raise $1000 ; $40000 would have to be spent by customers.
