A company sells herb blends for cooking. The tables below show the number of teaspoons for each herb in each blend and the cost for each blend.
What is the cost of basil per teaspoon?
o $0.15
o $0.18
o $0.19
o $0.23
Answer:
$0.23 or D
Step-by-step explanation:
Edg :)
The cost of one teaspoon of basil is $0.23. Therefore, option D is the correct answer.
We need to find the cost of basil per teaspoon.
How to interpret the data table?Interpretation of the data table is as follows:
Identify the subject under study.Identify the variable(s) presented in the table.Identify the measuring unit used (frequencies, percentages, rates, etc.)Read the information presented in table cells.Let the cost of one teaspoon of basil be $x, oregano be $y and parsley be $z.
Now, x+2y+3z=1.06-----(1), x+y+2z=0.72-----(2) and 2x+2y+z=0.99-----(3)
Equation (1)-(2), we get
x+2y+3z-(x+y+2z)=1.06-0.72
⇒y+z=0.34-----(4)
⇒z=0.34-y
Substitute z=0.34-y in equation (3).
That is, 2x+2y+0.34-y=0.99
⇒2x+y+0.34=0.99
⇒2x+y=0.65---(5)
Substitute z=0.34-y in equation (2)
Equation (5)-(4), we get
x+y+2(0.34-y)=0.72
⇒x+y+0.68-2y=0.72
⇒x-y=0.04-----(6)
Add equations (5) and (6), and we get
2x+y+x-y=0.65+0.04
⇒3x=0.69
⇒x=0.23
Therefore, the cost of basil per teaspoon is $0.23.

All the items on the sale rack were 75 percent off their original price.
If Jill bought an item on the sale rack and saved a total of $84, what is the value of x in the table above?
Answer:
112 $ is the original price
Step-by-step explanation:
[tex]x \times 0.75 = 84 \\ x = 84 \div 0.75 \\ x = 112[/tex]
you have to think that the original price multiplied by 0.75 (also known as 75%) gave the result of what he saves i.e 84 $. So we put up an equation with the original price multiplied by 75% which equals the 84 $ he saved on buying that item on sale
The value of x in the table above is $112.
How to find the percentage from the total value?Suppose the value of which a thing is expressed in percentage is "a'
Suppose the percent that considered thing is of "a" is b%
Then since percent shows per 100 (since cent means 100), thus we will first divide the whole part in 100 parts and then we multiply it with b so that we collect b items per 100 items(that is exactly what b per cent means).
Thus, that thing in number is
[tex]\dfrac{a}{100} \times b[/tex]
Given;
All the items on the sale rack were 75 percent off their original price.
Jill bought an item on the sale rack and saved a total of $84
Now,
Let the original price without off be x
84*100/x=75
8400/75=x
x=112
Therefore, the price without 75 percent of will be $112

Step-by-step explanation:
Before 1918, approximately 40% of the wolves in a region were male, and 60% were female. However, cattle ranchers in this area have made a determined effort to exterminate wolves. From 1918 to the present, approximately 60% of wolves in the region are male, and 40% are female. Biologists suspect that male wolves are more likely than females to return to an area where the population has been greatly reduced. (Round your answers to three decimal places.) (a) Before 1918, in a random sample of 10 wolves spotted in the region, what is the probability that 7 or more were male
Answer:
P(≥ 7 males) = 0.0548
Step-by-step explanation:
This is a binomial probability distribution problem.
We are told that Before 1918;
P(male) = 40% = 0.4
P(female) = 60% = 0.6
n = 10
Thus;probability that 7 or more were male is;
P(≥ 7 males) = P(7) + P(8) + P(9) + P(10)
Now, binomial probability formula is;
P(x) = [n!/((n - x)! × x!)] × p^(x) × q^(n - x)
Now, p = 0.4 and q = 0.6.
Also, n = 10
Thus;
P(7) = [10!/((10 - 7)! × 7!)] × 0.4^(7) × 0.6^(10 - 7)
P(7) = 0.0425
P(8) = [10!/((10 - 8)! × 8!)] × 0.4^(8) × 0.6^(10 - 8)
P(8) = 0.0106
P(9) = [10!/((10 - 9)! × 9!)] × 0.4^(9) × 0.6^(10 - 9)
P(9) = 0.0016
P(10) = [10!/((10 - 10)! × 10!)] × 0.4^(10) × 0.6^(10 - 10)
P(10) = 0.0001
Thus;
P(≥ 7 males) = 0.0425 + 0.0106 + 0.0016 + 0.0001 = 0.0548
3.2x-1.7x+5.5=10
How dI yoI solve this
The value of x is 0.918 for the equation 3.2x - 1.7x + 5.5 = 10.
To determine this equation 3.2x - 1.7x + 5.5 = 10,
3.2x - 1.7x + 5.5 = 10
Subtract 10 on both side,
3.2x - 1.7x + 5.5 - 10 = 10 - 10
3.2x - 1.7x + 4.5 = 0
Subtract 4.5 on both side,
3.2x - 1.7x = -4.5.
4.9x = -4.5
x = 0.918.
Therefore, the value of x is 0.918.

The first aircraft has 89 more seats than the second aircraft. The third aircraft has 45 fewer seats than the second aircraft. If their total number of seats is 401, find the number of seats for each aircraft
Answer: The first aircraft has 208 seats.
The second aircraft has 119 and the third has 74.
Step-by-step explanation:
The equation is x+89 + x + x-45 = 401
combine terms: 3x + 44 = 401 Subtract 44 from both sides 3x=357
divide both sides by 3
x= 119
substitute x in each term of the equation to find the number of seats on each aircraft
119 + 89 = 208 for #1 x= 119 for #2 119- 45= 74 for #3

Write an equation in points-slope form of the line that passes through (7,-6) and has the slope m= 1/2
Answer: point-slope form is [tex](y -y_{1} ) = m(x - x_{1} )[/tex]
9.5 -(-6) = 1/2(0-7)
Step-by-step explanation: You can get a y-intercept by substituting the x and y values from the given coordinate into the slope-intercept form and solve for b.
y = mx + b
-6 = 1/2(7) + b
-6 = 3.5 + b
-9.5 = b Slope-intercept equation for this question would be y = x/2 - 9.5
Then use the coordinates of the y-intercept to create the point-slope equation
(-9.5 -[-6]) = 1/2(0-7)

a) E[(3X+1)2]=
b) P(1≤X≤2)=
Answer:
a
[tex]E[(3X+1)^2]= 8.5 [/tex]
b
[tex]P(1 < X < 2)=0.1170 [/tex]
Step-by-step explanation:
From the question we are told that
The parameter of X is [tex]\lambda = 2[/tex]
Generally the expected value of X is
[tex]E(X) = \frac{1}{\lambda }[/tex]
[tex]E(X) = \frac{1}{2}[/tex]
=> [tex]E(X) = 0.50 [/tex]
Generally we have that
[tex]E(X^2) = E(X)^2 + E(X)^2[/tex]
=> [tex]E(X^2) = [\frac{1}{2}] ^2 + [\frac{1}{2} ]^2[/tex]
=> [tex]E(X^2) = 0.5 [/tex]
Generally
[tex]E[(3X+1)^2]= E(9x^2 + 1 + 6x)[/tex]
=> [tex]E[(3X+1)^2]= 9E[X^2] + 1 + 6 E[X])[/tex]
=> [tex]E[(3X+1)^2]= 9* 0.5 + 1 + 6 * 0.5 [/tex]
=> [tex]E[(3X+1)^2]= 8.5 [/tex]
Generally
[tex]P(1 < X < 2)= P(X < 2) - P(X < 1)[/tex]
Here [tex]P(X < 2 ) = e^{- 2 * \lambda }[/tex]
=> [tex]P(X < 2 ) = e^{- 2 * 2 }[/tex]
=> [tex]P(X < 2 ) = e^{- 4}[/tex]
and
[tex]P(X < 1 ) = e^{- 1 * \lambda }[/tex]
[tex]P(X < 1 ) = e^{- 1 * 2 }[/tex]
[tex]P(X < 1 ) = e^{-2 }[/tex]
So
[tex]P(1 < X < 2)= e^{-2 } - e^{- 4} [/tex]
[tex]P(1 < X < 2)=0.1170 [/tex]
round 67,103 and 1,273 to nearest hundred
Answer:
67100
1300
Step-by-step explanation:
You are rounding to the nearest hundreds place value (will be underlined and bolded). Note the number directly next to the place value (tens place value). If it is the digit 5 or greater, round up. If 4 or less, round down:
67103:
You are rounding to the hundreds place value. The tens place value is a 0. Because 0 is less than 5, round down.
67103 rounded to the nearest hundred is 67100.
1273:
You are rounding to the nearest hundreds place value. The tens place value is a 7. Because 7 is greater than 5, round up.
1273 rounded to the nearest hundred is 1300.

(6, 1)Reese loves to drink healthy green smoothies. A 16oz serving of smoothie has 170 calories. How many calories are in a 24oz smoothie?
Answer:
255 calories.
Step-by-step explanation:
There are many different ways to solve this, but I only know two.
First I noticed that 16 and 24 were both divisible by 4 so divided 16 by 4 and got 4. Then I divided 170 by 4 and got 42.5. So then I divided 24 by 4 and got 6. I multiplied 6 by 255.
OR
Divide 170 by 16 which gave me 10.625 which is the unit rate or constant of proportionality. So I multiplied 10.625 by 24 and got 255.

Assume that a procedure yields a binomial distribution with a trial repeated
n=5 times. Use some form of technology to find the probability distribution given the probability p=0.156 of success on a single trial.
Step-by-step explanation:
Use binomial probability:
P = nCr pʳ qⁿ⁻ʳ
where n is the number of trials,
r is the number of successes,
p is the probability of success,
and q is the probability of failure (1−p).
n = 5, p = 0.156, and q = 0.844.
r = 0, P = ₅C₀ (0.156)⁰ (0.844)⁵⁻⁰ = 0.428
r = 1, P = ₅C₁ (0.156)¹ (0.844)⁵⁻¹ = 0.396
r = 2, P = ₅C₂ (0.156)² (0.844)⁵⁻² = 0.146
r = 3, P = ₅C₃ (0.156)³ (0.844)⁵⁻³ = 0.027
r = 4, P = ₅C₄ (0.156)⁴ (0.844)⁵⁻⁴ = 0.002
r = 5, P = ₅C₅ (0.156)⁵ (0.844)⁵⁻⁵ ≈ 0
