Five hundred sixth-grade students
were surveyed. Of these students
that were surveyed...
• 375 had been to a baseball game
• 270 own either a cat or a dog
• 125 had traveled on an airplane
3) What is the ratio of total sixth-grade students to the number of students who either want a cat or a dog? (Write the ratio in THREE ways)
Answer:
The ratio in three ways are 500 : 125 or 100 : 25 or 4 : 1
Solution:
Given that,
Five hundred sixth-grade students were surveyed
Which means,
sixth-grade students = 500
125 had traveled on an airplane
What is the ratio of total sixth-grade students to the number of students who had traveled on an airplane?
Therefore,
total sixth-grade students : students traveled on airplane = 500 : 125
Ratio = 500 : 125
Reduce to lowest terms,
Divide both sides by 5
Ratio = 100 : 25
Further reduce to simplest terms,
Divide both sides by 25
Ratio = 4 : 1
Thus the ratio in three ways are 500 : 125 or 100 : 25 or 4 : 1

Simplify: −(−(−78))
Write answer in numerical value
Answer:
-78
Step-by-step explanation:
We need to find the value of -(-(-78))
We know that, -(-x) = +x
And -(-(-x)) = -x
We have,
x = 78
When two minus gets multiplied, we get a positive number and when a minus and a plus gets multiplied, we get a negative number. So,
-(-78) = +78
And
-(-(-78)) = -78
So, the numerical value is -78.
Find the value of x. Round to the nearest degree.

Curts kite is 36 yards above the ground and directly above the tree. The length of the string from Curt to the kite is 49 yards. How far is Curt from the tree?
Answer:
about 33.24 yards
Step-by-step explanation:
a² + b² = c²
so, 36² + b² = 49²
1296 + b² = 2401
b² = 1105
Take the square root of both sides..
b = 33.24 yards
Of the population of all fruit flies we wish to give a 90% confidence interval for the fraction which possess a gene which gives immunity to fungal infections. To this end we have obtained a random sample of 400 fruit flies. We find that 280 of the flies in the sample possess the gene. Give the margin of error for the 90% confidence interval. Round your answer to 3 decimal places.
Answer:
The margin of error for the 90% confidence interval is of 0.038.
Step-by-step explanation:
In a sample with a number n of people surveyed with a probability of a success of [tex]\pi[/tex], and a confidence level of [tex]1-\alpha[/tex], we have the following confidence interval of proportions.
[tex]\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]
In which
z is the zscore that has a pvalue of [tex]1 - \frac{\alpha}{2}[/tex].
The margin of error is of:
[tex]M = z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]
To this end we have obtained a random sample of 400 fruit flies. We find that 280 of the flies in the sample possess the gene.
This means that [tex]n = 400, \pi = \frac{280}{400} = 0.7[/tex]
90% confidence level
So [tex]\alpha = 0.1[/tex], z is the value of Z that has a pvalue of [tex]1 - \frac{0.1}{2} = 0.95[/tex], so [tex]Z = 1.645[/tex].
Margin of error:
[tex]M = z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]
[tex]M = 1.645\sqrt{\frac{0.7*0.3}{400}}[/tex]
[tex]M = 0.038[/tex]
The margin of error for the 90% confidence interval is of 0.038.
Find the missing side length please help!!!
Answer:
x = 15.9
Step-by-step explanation:
Recall: SOHCAHTOA
Reference angle = 25°
Opposite = x
Adjacent = 34
Apply the trigonometric function, TOA, since the Opp and Adj are involved
Thus:
Tan 25° = Opp/Adj
Tan 25° = x/34
34*Tan 25° = x
15.8544604 = x
x = 15.9 (nearest tenth)

Which system of linear equations has exactly one solution?
2y = 10x + 4
y = 5x - 2
y = 2x - 3
2y = x - 12
y = 8x + 3
y = 8x + 7
15y = 30x + 90
y = 2x + 6
Answer:
y = 2x - 3
2y = x - 12

both parents
B. The puppy inherits one gene from each parent and each gene contains
information for half of the puppy's traits,
c. The puppy inherits pairs of genes from its parents, and these gene pairs
determine the traits the puppy will possess.
D. The puppy inherits pairs of genes from each parent, and these genes contain
chromosomes that determine the puppy's traits

Find the area of the polygon shown. Enter the number into the box.
ft? 1 ft 4 ft 4 ft
Answer:
The area of the trapezium is 18 ft²
Step-by-step explanation:
Given;
Two parallel sides of the polygon as follows;
The first parallel side = 1 ft + 4 ft = 5 ft
The second parallel side = 4 ft
If this polygon is rotated 90 degrees, it forms a trapezium with a height of 4 ft.
The area of a trapezium is calculated as;
[tex]A rea= \frac{1}{2} (sum \ of \ parallel \ sides) \times height\\\\Area = \frac{1}{2} (5 \ + \ 4) \times 4\\\\Area = 18 \ ft^2[/tex]
Therefore, the area of the trapezium is 18 ft²

Help thank yoy if you do. Please eat if you havent today remember i love you
Please help! 25 points! Find the sum of the first 6 terms of the following series, to the nearest integer.
28, 112, 448,....
Answer:
595
Step-by-step explanation:
First term:
7
7 ⋅ 4 = 28
Second term:
28
28 ⋅ 4 = 112
Third term:
112
112 ⋅ 4 = 448
Fourth term:
448
This geometric sequence can be further described by the equation:
aₙ = 7 ⋅ 4 ⁿ⁻¹
So if you want to find the 4th term, n = 4
a ₄ = 7 ⋅ 4 ⁴⁻¹ = 7 ⋅ 4 ³ = 7 ⋅ 64 = 448
Note:
aₙ = a₁ rⁿ ⁻¹

what value is needed to complete the square?
X²-2x + _______
Answer:
[tex]X^2-2x+1[/tex]
Step-by-step explanation:
Traditional pattern for a perfect square:
[tex]x^{2} +2ax+a^{2}[/tex]
Which factors into: [tex](x+a)^2[/tex]
We know becuase a is "missing" from the original equation that it must equal 1; therefore:
[tex]x^2+2x+1[/tex]
Which we know is correct because it factors into: [tex](x+1)^2[/tex]
