Answer:
[tex]\frac{1}{4} * 3 = \frac{3}{4}[/tex]
Because:
[tex]\frac{1}{4} * 3 = \frac{1}{4} +\frac{1}{4} + \frac{1}{4}[/tex]
Step-by-step explanation:
Given
[tex]\frac{1}{4} * 3 = [\ ][/tex]
Because
[tex]\frac{1}{4} * 3 = [\ ] + [\ ] + [\ ][/tex]
Required
Fill in the box
[tex]\frac{1}{4} * 3 = [\ ][/tex]
This can be written as:
[tex]\frac{1}{4} * 3 = \frac{1* 3 }{4}[/tex]
Solve the numerator
[tex]\frac{1}{4} * 3 = \frac{3}{4}[/tex]
(b) Because
[tex]\frac{1}{4} * 3 = [\ ] + [\ ] + [\ ][/tex]
The above implies that
[tex]\frac{1}{4}[/tex] be added in 3 places
i.e.
[tex]\frac{1}{4} * 3 = \frac{1}{4} +\frac{1}{4} + \frac{1}{4}[/tex]

Complete the square to find
the vertex of this parabola.
x2 - 2x + y - 4 = 0
([?], [ ]
Answer:
1,5 should be correct this should be correct let me know and mark me brainless if it is thanks
The vertex of the parabola is,
⇒ (1, 5)
What is Quadratic equation?An algebraic equation with the second degree of the variable is called an Quadratic equation.
Given that;
The equation is,
x² - 2x + y - 4 = 0
Now, We can change it into vertex of this parabola as;
x² - 2x + y - 4 = 0
x² - 2x + 1 - 1 + y - 4 = 0
(x - 1)² + y - 5 = 0
(x - 1)² = - y + 5
(x - 1)² = - 1 (y - 5)
Thus, The vertex of the parabola is,
⇒ (1, 5)

The number of baby carrots in a bag is normally distributed with a mean of 94 carrots and a standard deviation of 8.2 carrots.
Approximately what percent of the bags of baby carrots have between 90 and 100 carrots?
23.3%
31.2%
45.5%
76.73%
Answer:
46% is the percent of the bags of baby carrots that have between 90 and 100 carrots
Step-by-step explanation:
The baby carrot is normally distributed.
z = (x - µ)/σ
x is equal to number of baby carrots
µ = mean
σ = standard deviation
Substituting the given values, we get -
90 ≤ x ≤ 100
z = (90 - 94)/8.2 = - 0.49
For z value of -0.49, the probability is 0.31
For x = 100
z = (100 - 94)/8.2 = 0.73
For z value of 0.73, the probability is 0.77
P(90 ≤ x ≤ 100) = 0.77 - 0.31 = 0.46
The percent of the bags of baby carrots having carrots between 90 and 100 carrots is 0.46 × 100 = 46%

G and H are mutually exclusive events. • P(G) = 0.5 • P(H) = 0.2
Answer:
[tex]P(G\ or\ H) = 0.7[/tex]
Step-by-step explanation:
Given
[tex]P(G) = 0.5[/tex]
[tex]P(H) = 0.2[/tex]
Required [Missing from the question]
[tex]P(G\ or\ H)[/tex]
Because the events are mutually exclusive, we use:
[tex]P(G\ or\ H) = P(G) + P(H)[/tex]
So, we have:
[tex]P(G\ or\ H) = 0.5 + 0.2[/tex]
[tex]P(G\ or\ H) = 0.7[/tex]

The ratio of the height to the base of a triangle is 3:4. If the base is 24 cm, what is its
area?
Answer:
height = 18 cm
Step-by-step explanation:
Let the height be 'x'
3 : 4 :: x : 24
Product of means = product of extremes
4 *x = 24 * 3
[tex]x = \frac{3 * 24}{4}\\\\x = 3 * 6\\\\x = 18[/tex]
Answer:
216cm^2
Step-by-step explanation:
If the ratio of height to base is 3:4 then
height = (3/4)*base
height = (3/4)*24cm = 18cm
Area = base*height/2 = 24cm * 18cm / 2 = 24cm * 9cm = 216cm^2

Henry runs business
preparing peoples taxes.
He has monthly expenses
off $25.30 for printer ink
and $52 for advertising.
So far his revenue for the
month has been $3,456,
what is the profit that he
had made?
Answer:
3,378.70
Step-by-step explanation:
First, find the total amount Henry spends a month. 25.30 for printer ink and 52 for advertising. 25.30+52=$77.30.
Subtract what he has spent from what he has made.
3,456-77.30=3,378.70
That is his profit.

Answer:
Probability for first letter to be a vowel is 5/11. When you take it out you’re left with 10 overall letters and 4 more vowels so the probability that the second letter is a vowel is 4/10 if you already took a vowel in the first take.
Probability for your occurence is (5/11)*(4/10)=20/110=2/11
Mary Jo spends $2,300 to buy stock in two companies. She pays $19 a share to one of the companies and $24 a share to the other. If she ends up with a total of 100 shares, how many shares did she buy at $19 a share and how many did she buy at $24 a share?
She bought ____ shares at $19 and ___ shares at $24.
Answer:
She bought _20___ shares at $19 and _80__ shares at $24.
Step-by-step explanation:
x + y = 100
19x + 24y = 2300
-19x - 19y = -1900
5y = 400
y = 80
x + 80 = 100
x = 20
She bought _20___ shares at $19 and _80__ shares at $24.

The first digits of data entries in most real-world data sets are not uniformly distributed. The most common first digit is 1, followed by 2, and so on, with 9 being the least common first digit. This phenomenon is known as Benford's Law.
The table below is the probability distribution for Benford's Law where the random variable D represents the first digit in a data entry.
What is the probability that a randomly selected data entry has a first digit greater than 7?
According to the given data,
Probability of D1 = 0.301Probability of D2 = 0.176By adding the probabilities, we get
→ [tex]P (D \leq = 2) = 0.301+0.176[/tex]
[tex]= 0.477[/tex]

An agricultural researcher wishes to see if a kelp extract prevents frost damage on tomato plants. two similar small plots are going to be planted with the same variety of tomato. plants in both plots are treated identically, expect the plants on plot 1 are going to be sprayed weekly with a kelp extract while the the plants in a plot 2 are not. let p1 and p2 be the actual proportion of all tomatoes of this variety that would experience crop damage under the kelp and no kelp treatments, respectively, when grown under conditions similar to those in the experiment. which of the following results would indicate that a difference exists between the two treatments?
(a) the 95% confidence interval for p1-p2 is (-0.279, -0.035).
(b) the 95% confidence interval for p1-p2 is (-0.279, 0.035)
(c) the 95% confidence interval for p1-p2 is (0.0279, 0.350)
(d) all of the above
(e) only (a) and (c)
Answer:
(E). only (a) and (c)
Step-by-step explanation:
H0 : p1 - p2 = 0
H1 : p1 - p2 ≠ 0
To indicate that difference exists between the two treatments, then we must reject the null and confidence interval must show that the difference between the two treatment is significant.
In other to use confidence interval to test for significance ; Intervals which do not contain 0 implies that difference exists and hence, the difference is significant.
The interval Given by : (-0.279, -0.035) is significant as the interval does not contain 0.
The interval Given by : (0.279, 0.035) is significant as the interval does not contain 0.
The interval Given by : (-0.279, 0.035) is not significant as the interval contains 0.
