Find the sum of the positive integers less than 200 which are not multiples of 4 and 7
Answer:
[tex]12942[/tex] is the sum of positive integers between [tex]1[/tex] (inclusive) and [tex]199[/tex] (inclusive) that are not multiples of [tex]4[/tex] and not multiples [tex]7[/tex].
Step-by-step explanation:
For an arithmetic series with:
[tex]a_1[/tex] as the first term, [tex]a_n[/tex] as the last term, and[tex]d[/tex] as the common difference,there would be [tex]\displaystyle \left(\frac{a_n - a_1}{d} + 1\right)[/tex] terms, where as the sum would be [tex]\displaystyle \frac{1}{2}\, \displaystyle \underbrace{\left(\frac{a_n - a_1}{d} + 1\right)}_\text{number of terms}\, (a_1 + a_n)[/tex].
Positive integers between [tex]1[/tex] (inclusive) and [tex]199[/tex] (inclusive) include:
[tex]1,\, 2,\, \dots,\, 199[/tex].
The common difference of this arithmetic series is [tex]1[/tex]. There would be [tex](199 - 1) + 1 = 199[/tex] terms. The sum of these integers would thus be:
[tex]\begin{aligned}\frac{1}{2}\times ((199 - 1) + 1) \times (1 + 199) = 19900 \end{aligned}[/tex].
Similarly, positive integers between [tex]1[/tex] (inclusive) and [tex]199[/tex] (inclusive) that are multiples of [tex]4[/tex] include:
[tex]4,\, 8,\, \dots,\, 196[/tex].
The common difference of this arithmetic series is [tex]4[/tex]. There would be [tex](196 - 4) / 4 + 1 = 49[/tex] terms. The sum of these integers would thus be:
[tex]\begin{aligned}\frac{1}{2}\times 49 \times (4 + 196) = 4900 \end{aligned}[/tex]
Positive integers between [tex]1[/tex] (inclusive) and [tex]199[/tex] (inclusive) that are multiples of [tex]7[/tex] include:
[tex]7,\, 14,\, \dots,\, 196[/tex].
The common difference of this arithmetic series is [tex]7[/tex]. There would be [tex](196 - 7) / 7 + 1 = 28[/tex] terms. The sum of these integers would thus be:
[tex]\begin{aligned}\frac{1}{2}\times 28 \times (7 + 196) = 2842 \end{aligned}[/tex]
Positive integers between [tex]1[/tex] (inclusive) and [tex]199[/tex] (inclusive) that are multiples of [tex]28[/tex] (integers that are both multiples of [tex]4[/tex] and multiples of [tex]7[/tex]) include:
[tex]28,\, 56,\, \dots,\, 196[/tex].
The common difference of this arithmetic series is [tex]28[/tex]. There would be [tex](196 - 28) / 28 + 1 = 7[/tex] terms. The sum of these integers would thus be:
[tex]\begin{aligned}\frac{1}{2}\times 7 \times (28 + 196) = 784 \end{aligned}[/tex].
The requested sum will be equal to:
the sum of all integers from [tex]1[/tex] to [tex]199[/tex], minus the sum of all integer multiples of [tex]4[/tex] between [tex]1\![/tex] and [tex]199\![/tex], and the sum integer multiples of [tex]7[/tex] between [tex]1[/tex] and [tex]199[/tex], plus the sum of all integer multiples of [tex]28[/tex] between [tex]1[/tex] and [tex]199[/tex]- these numbers were subtracted twice in the previous step and should be added back to the sum once.That is:
[tex]19900 - 4900 - 2842 + 784 = 12942[/tex].

The perimeter of a pool is 150 m. the rectangle at the right is a scale drawing of the pool. The length of each square on the grid represents 1 cm. draw another scale drawing of the pool using the scale 25 m to 2 cm. Explain why your drawing is accurate.
Answer:
Step-by-step explanation:
From the given rectangle,
Length of the rectangle = 5 cm
Width of the rectangle = 10 cm
Ratio of length : width = 1 : 2
Perimeter of the rectangle = 2(l + b)= 150 cm
l + b = 75 -----(1)
Since, l : b = 1 : 2
[tex]\frac{l}{b}= \frac{1}{2}[/tex]
b = 2l ------(2)
From equations (1) and (2),
l + 2l = 75
3l = 75
l = 25 m
Width 'b' = 2(25) = 50 m
Now we have to draw a rectangle with a scale = 25 : 2
Therefore, Scale factor = [tex]\frac{25}{l}=\frac{25}{2}[/tex]
l = 2 cm
Similarly,
[tex]\frac{50}{w}=\frac{25}{2}[/tex]
w = 4 cm
Now we can draw a rectangle with length = 2 cm and width = 4 cm.

A man standing 24 feet from a building observes the angle of elevation of its top to be 38°. Find the height of the building to the nearest tenth.
Answer:
The height of the building is 18.8 feet to the nearest tenth
Step-by-step explanation:
Whenever an elevation problem is given the first step is to try to visualize a triangular path between the objects that are given in the problem.
In this case, we can form a triangular path between the man, the top of the building, and the ground.
The height of the building we are looking for will be the opposite side of the triangle because it is directly facing the angle: 38 degrees.
The distance 24 feet will be the adjacent side of the triangle because it is adjacent to that angle
We can use the Tan trigonometric relationship to find a relationship between the length of the sides of the triangle and the available angles.
[tex]tan 38 = height/24ft[/tex]
[tex]height = 24 \times tan38 = 18.75ft[/tex] approximately 18.8 ft

If you want to arrange the tiles into a square, you will need 3.46 in each row/column.
This is physically impossible, hence you round it down to 3.
(If you round it up, you won't have enough tiles since [tex]4*4=16[/tex])
Thus, the square area will be [tex]3*3=9[/tex]

A poll of 1068 adult Americans reveals that 48% of the voters surveyed prefer the Democratic candidate for the presidency. At a 0.05 level of significance, test the claim that atleast half of all voters prefer the Democrat.
Answer:
Z = -1.333
P-value = 0.09176
Decision Rule: Reject [tex]H_o[/tex] if ∝ is greater than the P-value
Conclusion: Since P-value is > the level of significance ∝, we fail to reject the null hypothesis, therefore there is insufficient evidence to conclude that at least half of all voters prefer the Democrat.
Step-by-step explanation:
Given that:
The sample size of the poll = 1068
The proportion of voters that preferred Democratic candidate is [tex]\hat p[/tex] = 0.48
To test the claim that at least half of all voters prefer the Democrat, i.e 1/2 = 0.5
The null hypothesis and the alternative hypothesis can be computed as:
[tex]H_o : p \geq 0.50[/tex]
[tex]H_1 : p < 0.50[/tex]
Using the Z test statistics which can be expressed by the formula:
[tex]Z = \dfrac{\hat p - p}{\dfrac{\sqrt{p(1-p) }}{n}}}[/tex]
[tex]Z = \dfrac{0.48 - 0.5}{\dfrac{\sqrt{0.5(1-0.5) }}{1068}}}[/tex]
[tex]Z = \dfrac{-0.02}{\sqrt{\dfrac{{0.5(0.5) }}{1068}}}[/tex]
[tex]Z = \dfrac{-0.02}{\sqrt{\dfrac{{0.25}}{1068}}}[/tex]
[tex]Z = \dfrac{-0.02}{0.015}[/tex]
Z = -1.333
P-value = P(Z< -1.33)
From z tables,
P-value = 0.09176
The level of significance ∝ = 0.05
Decision Rule: Reject [tex]H_o[/tex] if ∝ is greater than the P-value
Conclusion: Since P-value is > the level of significance ∝, we fail to reject the null hypothesis, therefore there is insufficient evidence to conclude that at least half of all voters prefer the Democrat.
3m-n=km-8, solve for m
Add n on both sides:
3m = km - 8 + n
Subtract km on both sides:
3m - km = n - 8
Factor the Left-Hand Side:
m(3 - k) = n - 8
Divide both sides by (3 - k):
m = (n - 8) / (3 - k)
Answer:
(8-n)/(k-3) =m
Step-by-step explanation:
3m-n=km-8
Subtract 3m from each side
3m -3m-n=km -3m-8
-n =km -3m-8
Add 8 to each side
8-n =km -3m-8+8
8-n =km -3m
Factor out m
8-n =m(k -3)
Divide by (k-3)
(8-n)/(k-3) =m(k -3)/( k-3)
(8-n)/(k-3) =m
Four less than three times a number increased by six times the same number is 32
what’s the answer?
-11
-4
—4
-7
Answer:
Step-by-step explanation:
Let the unknown number be x;
for Four less than three times a number, it is expressed as (3x-4)
If the number gotten is increased by six times the same number, the equation becomes 3x-4+6x
If they are all equal to 32 then;
3x-4+6x = 32
We are to look for the value of x from the expression;
3x-4+6x = 32
-4+9x = 32
add 4 to both sides
-4+9x+4 = 32+4
+9x = 36
x = 36/9
x = 4
Hence the answer to the unknown number is 4

One angle of an octagon is 65º. The
others are equal to each other. Find them.
x = 145°
Step-by-step explanation:the sum of interior angles of octagon formula
S = (n - 2)×180°
n = 8
S = (8 - 2)×180°
S = 6×180°
S = 1080°
we have 1 angle = 65° & others are equal to each other
1080° - 65° = 7x
7x = 1015°
x = 1015° : 7
x = 145°
Elizabeth claims that the only square root of 36 is 6. Which statement below disproves Elizabeth’s claim? A) 6 is a factor of 36. B )36 has both even and odd factors. C) The square root of a whole number is sometimes a decimal value. D) The square root of a positive number can be a negative or positive value.
Answer:
D) The square root of a positive number can be a negative or positive value.
Step-by-step explanation:
36 is a perfect square, meaning that the square root of 36 is equivalent to an integer, 6, whereby, the integer 6, when multiplied by itself gives us the perfect square, 36.
i.e. 36 = 6*6 = 6²
√36 = √6² = 6
There are actually two possible square root of 36. That is -6.
Square of, -6², equivalently is -6 * -6 = 36.
Therefore, √36 = ±6.
So, her claim is wrong. 6 is not the only square root of 36.
Square root of 36 could be negative 6 or positive 6.

Any value of x
Step-by-step explanation:
Given
[tex]f(x) = \sqrt{x^2 - 1}[/tex]
[tex]g(x) = \sqrt{x^2 + 1}[/tex]
Required
What value of x is [tex]f(g(x)) = g(f(x))[/tex]
Solving for f(g(x))
[tex]f(x) = \sqrt{x^2 - 1}[/tex]
[tex]f(g(x)) = \sqrt{(\sqrt{x^2 + 1})^2 - 1}[/tex]
Solve the inner square
[tex]f(g(x)) = \sqrt{(x^2 + 1 - 1}[/tex]
[tex]f(g(x)) = \sqrt{x^2 } }[/tex]
[tex]f(g(x)) = x[/tex]
Solving g(f(x))
[tex]g(x) = \sqrt{x^2 + 1}[/tex]
[tex]g(f(x)) = \sqrt{(\sqrt{x^2 - 1})^2 + 1}[/tex]
[tex]g(f(x)) = \sqrt{x^2 - 1 + 1}[/tex]
[tex]g(f(x)) = \sqrt{x^2 }[/tex]
[tex]g(f(x)) = x[/tex]
Equate f(g(x)) and g(f(x))
[tex]f(g(x)) = g(f(x))[/tex]
[tex]x = x[/tex]
This implies that [tex]f(g(x)) = g(f(x))[/tex] at any value of x
