Answer:
Below in bold.
Step-by-step explanation:
Let the number of pistachios be x then the number of almonds = x-100.
The number of cashews = 1000 - x - (x - 100) = 1100-2x.
From the info given
3(1100-2x) + 4x + 5(x - 100) = 3700
3300 - 6x + 4x + 5x - 500 = 3700
3x = 3700 - 3300 + 500
3x = 900
x = 300
So there are 300 pistachios, 200 almonds and 500 cashews in the bag.
There are 300 pistachios, 200 almonds, and 500 cashews in the bag of mixed nuts.
To find the number of each type of nut in the bag, we can set up a system of equations based on the given information.
Let's assume there are x pistachios in the bag. According to the problem, there are 100 fewer almonds than pistachios, so the number of almonds will be (x - 100).
Now, the total number of nuts is 1,000:
x (pistachios) + (x - 100) (almonds) + cashews = 1000
The total weight of the nuts in the bag can be calculated as follows:
3g (cashews) * number of cashews + 4g (pistachios) * x + 5g (almonds) * (x - 100) = Total weight in grams.
Since we know that the bag weighs 3.7 kg, we need to convert the total weight to grams and set it equal to 3.7 kg * 1000g/kg = 3700g.
Now we have two equations:
x + (x - 100) + cashews = 1000
3g * cashews + 4g * x + 5g * (x - 100) = 3700
Let's simplify equation 1:
2x - 100 + cashews = 1000
2x + cashews = 1100
cashews = 1100 - 2x
Now, let's substitute the expression for cashews in equation 2:
3g * (1100 - 2x) + 4g * x + 5g * (x - 100) = 3700
Now, distribute the weights:
3300g - 6g * x + 4g * x + 5g * x - 500g = 3700
Combine like terms:
-6g * x + 4g * x + 5g * x = 3700 - 3300 + 500
3g * x = 900
x = 900 / 3
x = 300
Now that we have the value of x (number of pistachios), let's find the number of almonds:
almonds = x - 100
almonds = 300 - 100
almonds = 200
Now, let's find the number of cashews using the total nut count:
cashews = 1000 - (pistachios + almonds)
cashews = 1000 - (300 + 200)
cashews = 1000 - 500
cashews = 500

The perimeter of the original rectangle is 17.6mm. The side length of the enlarged rectangle is 23.22mm and the perimeter of the enlarged rectangle is 95.04mm
Perimeter of a rectangleThe formula for calculating the perimeter of a rectangle is expressed as;
P = 2(l +w)
If the smaller rectangle has a length of 4.3 millimeters and width of 4.5 millimeters while a larger rectangle has a length of x millimeters and width of 24.3 millimeters, then;
4.3/x = 4.5/24.3

Step-by-step explanation:
$15,074 is invested, part at 14% and the rest at 5%. If the interest earned from the amount invested at 14% exceeds the interest earned from the amount invested at 5% by $1694.07, how much is invested at each rate? (Round to two decimal places if necessary.)
The rate at 14% and 5% are $12, 883 and $2191 respectively.
How to determine the rateGiven that;
Invested amount = $ 15, 074 at 14% and 5%
Let rate at 14% = x
rate at 5% = y
We have rate at 9% exceeds that of 5% by $1694. 07
Hence,
0. 14x = 0. 05y + $1694. 07 ⇒ equation 1
x + y = $15, 074 ⇒ equation 2
Make 'x' the subject
x = [tex]15, 074 - y[/tex]
Substitute in equation 2
[tex]0. 14(15, 074 - y) = 0. 05y + $1694. 07[/tex]
Expand the expression
[tex]2, 110. 36 - 0. 14y = 0.05y + 1694. 07[/tex]
Collect like terms
[tex]416. 29 = 0. 19y[/tex]
Make 'y' the subject
y = [tex]\frac{416. 29}{0. 19}[/tex]
y = [tex]$2, 191[/tex]
Substitute the value in equation 2
x + y = $15, 074
x = $15, 074 - y
x = [tex]$15, 074 - 2191[/tex]
x = $12, 883
Therefore , the rate at 14% and 5% are $12, 883 and $2191 respectively.

The equation y minus 1 = negative 7 (x minus 3). is written in point-slope form. What is the y-intercept of the line?
Answer:
(0, 22)
Step-by-step explanation:
So you have the equation:
[tex]y-1=-7(x-3)[/tex]
So first let's define what the "y-intercept" is. The y-intercept, of a line is like the name implies, when the line intercepts or "passes" the y-axis. And if you were to take any point on the y-axis, the y-value may vary, but there is one value that doesn't change, and that's the x-value. the x-value is always going to be zero, no matter where you are on the y-axis. So to find the y-intercept simple plug 0 in as x. This gives you the equation:
[tex]y-1 = -7(0-3)[/tex]
[tex]y-1 = -7(-3)[/tex]
[tex]y-1=21[/tex]
[tex]y=22[/tex]
So the y-intercept is at (0, 22)
Which type of parent function is f(x) = -
1/?
O A. Absolute value
OB. Reciprocal
OC. Square root
OD. Linear
Answer: B. Reciprocal
Step-by-step explanation:
This is a fact.
The parent function represented by f(x) = -1/x is the reciprocal function.
Therefore, the correct answer is option B.
Reciprocal functions, also known as rational functions, are defined by an algebraic expression where the dependent variable is in the denominator. In this case, the dependent variable is x, and it appears in the denominator as 1/x.
The negative sign in front of the fraction simply indicates that the function is reflected over the x-axis.
The general form of a reciprocal function is f(x) = a/x, where "a" is a constant. In the given function f(x) = -1/x, a is equal to -1.
In the case of f(x) = -1/x, the graph of the function is a hyperbola that opens downwards in the first and third quadrants. It approaches the x-axis as x moves towards positive or negative infinity, and it moves away from the x-axis as x approaches 0.
Therefore, the correct answer is option B, the reciprocal function.

The confidence interval is (-1.1059, 7.70459).
What is confidence interval in statistics?Image result for what is confidence interval
A confidence interval is the mean of your estimate plus and minus the variation in that estimate.
The sample mean is M=3.3
The sample size is N=44
So, σM= s/√N = 16.6/ √44
= 16.6/ 6.633
= 2.621
and, the degree of freedom
df= n-1
=44-1
=43
So, The t-value for a 90% confidence interval and 43 degrees of freedom is t=1.681.
Now, Margin of error = 2.261* 1.681 = 4.4059
Now, the lower and upper bound of the confidence interval are:
LL = 3.3- 4.40459 = -1.1059
UL = 3.3+ 4.40459 = 7.70459
Hence, the confidence interval is (-1.1059, 7.70459).

What is the least 6 digit multiple of 4 that has all different numbers?
Answer:
We can now take 2 as the third digit, 3 as the fourth digit, 4 as the fifth digit and finally 5 as the sixth digit. Therefore, the smallest 6-digit number having all different digits is 102345.
The smallest 6-digit multiple of 4 with all different numbers is 102,564. This number is obtained by incrementing from 100,000 until finding a divisible number with distinct digits.
A number that is the result of a given number plus another natural number is said to be a multiple of that number.
Since the smallest 6-digit number, is 100,000.
Check if this number is divisible by 4.

There are chocolates in a box, all identically shaped. There are 8 filled with nuts, 16 with caramel, and 14 are solid chocolate. You randomly select one piece, eat it, and then select a second piece. Find the probability of selecting 2 solid chocolates in a row.
Answer:
P = [tex]\frac{91}{703}[/tex] ≅ 12.95%.
Step-by-step explanation:
The total amount of chocolates in the box is 8 + 16 + 14 = 38, 14 of which are solid.
Let's calculate the probability of getting a solid chocolate in the first selection:
[tex]P(1S) = \frac{14}{38} = \frac{7}{19}.[/tex]
Given that the first piece was solid, there are now 37 pieces of chocolate in the box, 13 of which are solid. Let's now calculate the probability of selecting another solid chocolate:
[tex]P(2S\,|\,1S) = \frac{13}{37}.[/tex]
Thus, the probability of selecting two solid chocolates in a row is the product of the two probabilities calculated above:

C)(6, negative pi divided by 5 + (2n + 1)π) or (-6, negative pi divided by 5 + 2nπ)
D) (6, negative pi divided by 5 + 2nπ) or (6, pi divided by 5 + (2n + 1)π)
All polar coordinates of point P where P = ordered are given are mathematically given as
(6, negative pi divided by 5 + 2nπ) or (-6, negative pi divided by 5 + (2n + 1)π)
Option B is correct.
What are all polar coordinates of point P where P = ordered pair 6 commas negative pi divided by 5.?Generally, the equation for all polar coordinates is mathematically given as
[tex]P= 6,\frac{-pi}{5}[/tex]
Finding the whole set of polar coordinates for An arbitrary point's polar coordinates may be written as (r, ), where (r, ) = (r, +2n) for some n and r.
If n is a positive integer and r is negative, then (r,) = (-r, +(2n+1)).
In conclusion, we may solve the problem by setting r = 6 and = -/6.
If n is an integer and r is positive, then P(6,-/6) = (6, -/6) + 2n, and if n is an integer and r is negative, then P(-6,-/6) = (-6, -/6) + (2n+1).
