-9x + 2y= -7
-12x + 3y= -9
Answer:
1, 1
(x is equal to 1 and y is equal to 1)
Step-by-step explanation:
System:
{ -9x + 2y= -7
{ -12x + 3y= -9
Getting a single x value:
[Given] -9x + 2y= -7
[Add 9x + 7 to both sides & then flip the equation] 9x = 2y + 7
[Divide both sides of the equation by 9] x = \(\frac{2}{9}\)y + \(\frac{7}{9}\)
Solving for y by plugging-in our x:
[Equation] -12x + 3y= -9
[Plug-in] -12(\(\frac{2}{9}\)y + \(\frac{7}{9}\)) + 3(\(\frac{2}{9}\)y + \(\frac{7}{9}\)) = -9
[Distribute -12 and 3] \(\frac{-24y}{9}\) + \(\frac{-84}{9}\) + \(\frac{6y}{9}\) + \(\frac{21}{9}\) = -9
[Multiply both sides of the equation by 9] -24y -84 + 6y + 21 = -81
[Combine like terms & add 63 to both sides] -18y = -18
[Divide both sides by -18] y = 1
Solve for x by plugging-in y,
[Given] -9x + 2y= -7
[Plug-in] -9x + 2(1) = -7
[Multiply] -9x + 2 = -7
[Subtract 2 from both sides] -9x = -9
[Divide both sides by -9] x = 1

Construct both a 98% and a 80% confidence interval for B₁. B₁=46, s=5.7, SSzz = 57, n = 12 98%:
To construct a 98% confidence interval for B₁, we can use the t-distribution since the sample size is small (n = 12).
Given the sample mean (B₁ = 46), sample standard deviation (s = 5.7), and sum of squares (SSzz = 57), we can calculate the confidence interval.
The formula for a confidence interval is:
Confidence Interval = Sample Mean ± (Critical Value * Standard Error)
For a 98% confidence level and n = 12, the critical value is approximately 2.681 (obtained from a t-distribution table).
The standard error is calculated as the sample standard deviation divided by the square root of the sample size (s / √n).
Plugging in the values:
Standard Error = 5.7 / √12 ≈ 1.647
Confidence Interval = 46 ± (2.681 * 1.647)
Therefore, the 98% confidence interval for B₁ is approximately (42.21, 49.79).
In conclusion, we can be 98% confident that the true value of B₁ falls within the range of 42.21 to 49.79 based on the given sample data.

You have 95 coins, consisting of nickels, dimes, and quarters. The value of the coins is $13. 70. There are 11 more quarters than dimes. Which system of equations can be used to represent this situation, where n is the number of nickels, d is the number of dimes, and q is the number of quarters?.
So, the system of equations representing this situation is: n + d + q = 95; 0.05n + 0.10d + 0.25q = 13.70; q = d + 11.
To represent this situation with a system of equations, we can use the following equations:
The total number of coins: n + d + q = 95
The total value of the coins in dollars: 0.05n + 0.10d + 0.25q = 13.70
The relationship between the number of quarters and dimes: q = d + 11
The first equation represents the total number of coins, which is given as 95.
The second equation represents the total value of the coins in dollars, which is given as $13.70. The values of each coin (nickel, dime, quarter) are multiplied by their respective quantities (n, d, q) and summed up to obtain the total value.
The third equation represents the relationship between the number of quarters (q) and dimes (d), which states that there are 11 more quarters than dimes.

Write the series (-3)+(-1)+3+9+.....+97 to n terms in sigma notation
The series (-3)+(-1)+3+9+...+97 to n terms can be expressed in sigma notation as: ∑_{k=1}ⁿ ((k-1) + 97(-1)\(^k\)).
The series starts with -3 and each term is obtained by multiplying the previous term by -1 and then adding 4 to it. We can express this recurrence relation using the formula:
a_{n+1} = -a_n + 4
where a_1 = -3.
To write this series in sigma notation, we can use the following formula:
∑_{k=1}ⁿ a_k = a_1 + a_2 + ... + a_n
Substituting the recurrence relation for a_k, we get:
∑_{k=1}ⁿ a_k = -3 + (-3+4) + (-(-3+4)+4) + ... + (-1)⁽ⁿ⁻¹⁾(-3+4) + (-1)ⁿ(97)
Simplifying this expression, we can factor out -3+4 from each term:
∑_{k=1}ⁿ a_k = (-3+4) + (-3+4) + (-3+4) + ... + (-3+4) + (-3+4) + 97(-1)ⁿ
There are n-1 terms of (-3+4), and the last term is 97(-1)ⁿ. Therefore, we can write:
∑_{k=1}ⁿ a_k = (n-1)(-3+4) + 97(-1)ⁿ
Simplifying this expression, we get:
∑_{k=1}ⁿ a_k = (n-1) + 97(-1)ⁿ

the perimeter of a rectangle is 260cm the length is 50 less than its width. find its dimensions
The dimensions of the rectangle is found as: (b = 90 cm) and (l = 40 cm
).
What is defined as the perimeter of the rectangle?The perimeter (P) of such a rectangle has been the total length of all of its sides. A rectangle does have two equal lengths as well as two equal widths because its opposite sides are equal. The perimeter of a rectangle is calculated as follows: perimeter = length + length + width + widthLet 'l' be the length of the rectangle.
Let 'b' be the width of the rectangle.
then,
Perimeter = 2(l + b)
The given value of the perimeter = 260 cm.
The length is 50 less than the width.
Thus, l = b - 50.
Put the values in the formula;
260 = 2( b - 50 + b)
Simplify the equation;
260 = 4b - 100
4b = 360
b = 90 cm
Put the value of b in the length;
l = b - 50
l = 90 - 50
l = 40 cm
The dimension are estimated as; (l = 40 cm) and (b = 90 cm).

the tiros weather satellites were a series of weather satellites that carried television and infrared cameras and were covered by solar cells. if the cylindrical shaped body of a tiros had a diameter of 42 inches and a height of 19 inches, what was the volume available to carry instruments and cameras?
The volume available to carry instruments and cameras inside the cylindrical body of a TIROS weather satellite is approximately 26,336.5 cubic inches.
To find the volume of the cylindrical-shaped body of a TIROS weather satellite, we can use the formula for the volume of a cylinder: V = πr²h. In this case, the diameter is 42 inches, so the radius (r) is half of that, which is 21 inches. The height (h) is 19 inches.
Step 1: Calculate the radius (r) by dividing the diameter by 2.
r = 42 inches / 2 = 21 inches
Step 2: Calculate the square of the radius (r²).
r² = 21 inches × 21 inches = 441 square inches
Step 3: Multiply the square of the radius (r²) by the height (h).
Volume (V) = 441 square inches × 19 inches = 8379 cubic inches
Step 4: Multiply the result by π (approximately 3.1416).
V = 8379 cubic inches × 3.1416 ≈ 26,336.5 cubic inches

A bakery sells cakes and pies. Let c represent the number of cakes and p represent the number of pies. The following system of equations are used to find the number of cakes and pies the bakery sold on Friday. What number would you multiply the first equation to eliminate the number of cakes and find the number of pies?c – p = 98c + 14p = 402
you would multiply the first equation by 8 to eliminate the number of cakes and find that the bakery sold 15 pies on Friday.
To eliminate the number of cakes (c) and find the number of pies (p), you would need to multiply the first equation by a suitable number so that the coefficients of 'c' in both equations become equal.
The given system of equations is:
1) c - p = 9
2) 8c + 14p = 402
To eliminate 'c', you should multiply the first equation by 8:
8(c - p) = 8(9)
8c - 8p = 72
Now, the modified system of equations is:
1) 8c - 8p = 72
2) 8c + 14p = 402
Next, subtract the first equation from the second equation to eliminate 'c':
(8c + 14p) - (8c - 8p) = 402 - 72
8c + 14p - 8c + 8p = 330
22p = 330
Finally, divide both sides of the equation by 22 to find the number of pies (p):
22p / 22 = 330 / 22
p = 15
So, you would multiply the first equation by 8 to eliminate the number of cakes and find that the bakery sold 15 pies on Friday.

2.28 socks in a drawer. in your sock drawer you have 4 blue, 5 gray, and 3 black socks. half asleep one morning you grab 2 socks at random and put them on. find the probability you end up wearing
The probability that you end up wearing two socks of the same color is approximately 0.288 or 28.8%.
To find the probability of randomly selecting and wearing two socks of a specific color, we need to consider the total number of possible outcomes and the number of favorable outcomes.
Total number of possible outcomes:
There are a total of 12 socks in the drawer. When you randomly select two socks, there are 12C2 (combinations of 2 from 12) ways to do this.
12C2 = (12 x 11) / (2 x 1) = 66
So, there are 66 possible ways to select two socks from the drawer.
Number of favorable outcomes:
We need to find the number of ways to select two socks of the same color. There are three different possibilities for this - blue, gray, or black socks.
Number of ways to select two blue socks: 4C2 = (4 x 3) / (2 x 1) = 6
Number of ways to select two gray socks: 5C2 = (5 x 4) / (2 x 1) = 10
Number of ways to select two black socks: 3C2 = (3 x 2) / (2 x 1) = 3
Therefore, the total number of favorable outcomes is 6 + 10 + 3 = 19.
So, the probability of randomly selecting and wearing two socks of the same color is:
P(selecting and wearing two socks of the same color) = number of favorable outcomes / total number of possible outcomes
P(selecting and wearing two socks of the same color) = 19 / 66
P(selecting and wearing two socks of the same color) ≈ 0.288
