A baker made 28 wedding cakes in 84 days . What is equivalent to the ratio of 28:84?
The baker have an equivalent of 1: 3 to the ratio of 28 : 84, of the number of cakes to the number of days.
Expression of ratio as fractionsRatio is used to compare values, and can be expressed as fractions.
The baker has the ratio of the number of cakes to the number of days made as 28 : 84 and can be expressed as follows;
28 : 84 = 28/84 {in fraction}
the fraction 28/84 has an equivalent fraction by dividing the numerator and denominator by the same factor
28 : 84 = (28 × 1)/(28 × 3)
divide through by 28
28 : 84 = 1/3
Therefore, the the ratio 1 : 3 us the equivalent to the ratio of the number of cakes to the number of days given as 28 : 84.

If the probability that an identified hurricane will make a direct hit on a certain stretch of beach is 1/4, what are the odds against a direct hit?
A)3 to 1
B)1 to 3
C)1 to 4
The odds against a direct hit is 3 to 1.
Given that the probability of a hurricane hitting at a coast is 1/4 = 0.25.
Therefore, the probability of not hitting = 1-0.25
= 0.75
we know that,
Odds against direct hit = [P(no direct hit)]/P[(direct hit)] = 0.75/0.25 = 3/1
= 3:1
Hence the odds against a direct hit is 3 to 1.

A statistics class was given a pretest on probability (since many had previous experience in some other class). Then the class was given a six-page review handout to study for two days. At the next class they were given another test. Is there sufficient evidence that the scores improved?
Answer:
No, there is not sufficient evidence that the scores improved.
Step-by-step explanation:
Just because these people were given a six-page review handout doesn't mean that:
a. They actually did any of it
b. They learned anything
c. Since the kids have other experiences in class, the scores might not have necessarily improved that much, if at all
d. They had enough time to study
e. They cared enough in the first place
Generally, there is no rock-solid evidence at all pointing to the fact that their test scores improved. While you could make the assumption assuming every kid did what they were supposed to do, there isn't enough evidence to say that the scores improved.

For all real values of .x such that -1
We are going to analyze each answer
A. x
In this answer -1 < x < 0, then its greatest value is 0
B. 2x
Since -1 < x < 0. In this answer:
-1 · 2 < x · 2 < 0 ·2 [multiplying each term by 2]
-2 < 2x < 0
then the greatest value of 2x is 0
C. x + 1
Since -1 < x < 0. In this answer:
-1 + 1 < x + 1 < 0 + 1 [adding 1 on each term]
0 < x + 1 < 1
then the greatest value of x + 1 is 1
D. 1/x
Since -1 < x < 0 then -1 < x and x < 0. In this answer:
-1 / x > x / x and x / x > 0 / x [We divide by x each term]
- 1 / x > 1 and 1 > 0
1 / x < - 1 [multiplying by -1]
then the greatest value of 1 / x is -1
E. -1/x
On the last answer (D) we found in the second step that - 1 / x > 1
Then the greatest value of -1/x is infinite
Answer: EA triangular pane of glass has a height of 32 inches and an area of 352 square inches. What is the length of the base of the pane?
The required length of the base of the triangular pane of glass is 22 inches.
We know that the formula for the area of a triangle is:
Area = 1/2 * base * height
We are given that the height of the triangular pane of glass is 32 inches and the area is 352 square inches. Substituting these values into the formula, we get:
352 = 1/2 * base * 32
Multiplying both sides by 2 and dividing by 32, we get:
base = 22
Therefore, the length of the base of the triangular pane of glass is 22 inches.

8 jars has an equal number of marbles. The remaining marbles are
then put into the 9th jar. How many more marbles does she need for
the 9th jar such that every jar has the same number of marbles?
Answer:
She needs 4 more marbles for the 9th jar.
Step-by-step explanation:
Multiples of 8:
M = {0, 8, 16, 24, 32, 40, 48, 56, ...}
First, she puts in the greatest possible number of marbles into each of the 1st 8 jars.
The total is the greatest multiple of 8 below 50, which is 48.
In each jar:
48/8 = 6
The remaining marbles are then put into the 9th jar.
50 - 48 = 2 in the 9th jar.
How many more marbles does she need for the 9th jar such that every jar has the same number of marbles?
All others have 6, the 9th has 2.
6 - 2 = 4
She needs 4 more marbles for the 9th jar.

Determine how many liters a right circular cylindrical tank holds if it is 6 m long and 13 m in diameter.
The tank holds approximately 994,040 liters.
To solve this problem
The volume of a right circular cylinder is given by the formula:
V = πr^2h
Where
r is the radius of the cylinderh is its height π is a mathematical constant approximately equal to 3.14159The cylinder's diameter is specified as 13 m, hence the radius may be computed using the formula: r = d/2 = 13/2 = 6.5 m
The cylinder is described as having a 6 m length.
These values are substituted into the volume calculation to produce the following result:
V = π(6.5)^2(6)
V ≈ 994.04 cubic meters
Since 1 cubic meter equals 1000 liters, we can convert the volume to liters by multiplying by 1000.
V = 994.04 cubic meters x 1000 liters/cubic meter
V = 994,040 liters
Therefore, the tank holds approximately 994,040 liters.

Given a normal population whose mean is 555 and whose standard deviation is 72, find each of the following:
The probability that a random sample of 21 has a mean between 564 and 587.
Probability =
The probability that a random sample of 21 has a mean between 564 and 587 is of:
0.2641 = 26.41%.
How to obtain probabilities using the normal distribution?The z-score of a measure X of a variable that has mean symbolized by \(\mu\) and standard deviation symbolized by \(\sigma\) is obtained by the rule presented as follows:
\(Z = \frac{X - \mu}{\sigma}\)
The z-score represents how many standard deviations the measure X is above or below the mean of the distribution, depending if the obtained z-score is positive or negative.Using the z-score table, the p-value associated with the calculated z-score is found, and it represents the percentile of the measure X in the distribution.The parameters for this problem are given as follows:
\(\mu = 555, \sigma = 72, n = 21, s = \frac{72}{\sqrt{21}} = 15.7\)
The probability that a random sample of 21 has a mean between 564 and 587 is the p-value of Z when X = 587 subtracted by the p-value of Z when X = 564, hence:
X = 587:
\(Z = \frac{X - \mu}{\sigma}\)
By the Central Limit Theorem
\(Z = \frac{X - \mu}{s}\)
Z = (587 - 555)/15.7
Z = 2.04
Z = 2.04 has a p-value of 0.9798.
X = 564:
Z = (564 - 555)/15.7
Z = 0.57
Z = 0.57 has a p-value of 0.7157.
0.9798 - 0.7157 = 0.2641 = 26.41%.

What is a parallelogram?In Euclidean geometry, a parallelogram is a simple quadrilateral with two pairs of parallel sides. The opposite or facing sides of a parallelogram are of equal length and the opposite angles of a parallelogram are of equal measure.
Given is a parallelogram.
We can write -
∠A = 76° + ∠1
∠C = 37° + ∠5
In a parallelogram, the opposite angles are equal. Therefore, we can write -
∠A = ∠C
76° + ∠1 = 37° + ∠5
37° + ∠5
∠1 = 37° (Alt. interior angles)
76° + 37° = 37° + ∠5
∠5 = 76°

Answer:
x = 71
Step-by-step explanation:
The base angles of an isosceles triangle are congruent. The sum of angles in a triangle is 180°.
x° +x° +38° = 180°
2x = 142 . . . . . . . . divide by °, subtract 38
x = 71 . . . . . . . . . divide by 2
\(\huge\bf\underline{\underline{\pink{A}\orange{N}\blue{S}\green{W}\red{E}\purple{R:-}}}\)
Let the given triangle be ∆ABC and let B and C be the base of triangle. As per the property we know that the bases of isosceles triangle are congruent or equal.
Also, sum of all angles in triangle is 180°.
By further simplification we get,
\(:\implies\tt{x + x + 38 = 180}\)
\(:\implies\tt{2x + 38 = 180}\)
