Quantity of water with Henri = 16 litres

Quantify of water he will need for one cup of coffee = 200 ml

Number of cups of coffee he can make with a full cup of water :-

\( = 16 \: litres \: = 16000 \: ml\)

\( = \frac{16000}{200} \)

\( = 80 \: cups \: of \: coffee\)

So , Henri can make 80 cups of coffee with one full bottle of water .

Quantity of water needed to make 80 cups of coffee = 16,000 ml

Quantity of water needed to make one cup of coffee :-

\( = \frac{16000}{80} \)

\( = 200 \: ml\)

So , 200 ml of water is needed to make one cup coffee .

Quantity of water he needs to make 250 cups of coffee :-

\( = 200 \times 250\)

\( = 50000 \: ml\)

So , Henri needs 50,000 ml of water to make 250 cups of coffee .

Number of water containers he will use :-

\( = \frac{50000}{16000} \)

\( = 3.125 \\ = 3 \: water \: containers\)

So , Henri will use 3 full water containers to make 250 cups of coffee .

Money charged per one coffee = 8 cents

Money charged for 250 coffees :-

\( = 250 \times 8\)

\( = 2000 \: cents\)

So , Henri will make 2000 cents if he sells 250 cups of coffee .

Therefore , Henri will use 3 full containers of water to make 250 cups of coffee and he he will make 2000 cents by selling 250 cups of coffee .

The equation of the axis of symmetry of the parabola is equal to x = 4.

In this problem we find the representation of a parabola whose axis of symmetry is parallel with y-axis. The axis of symmetry passes through the vertex of the parabola. The definitions of the vertex and the axis of symmetry are, respectively:

Vertex

(x, y) = (h, k)

Axis of symmetry

x = h

If we know that h = - 4, then the equation of axis of symmetry is x = 4.

Pennies will yield the greatest level of accuracy when measuring the weight of a large rock on a pan balance.

To measure the weight of a large rock using a pan balance and achieve the greatest level of accuracy with the least error, you should use pennies.

Here's why:
Potatoes: They have varying shapes and sizes, which would make it difficult to achieve an accurate measurement.
Sand: It is difficult to control the amount and could lead to inconsistent measurements.
Bricks: They are too large and may not provide the required level of accuracy, as they might not have consistent weights.
Pennies: They have a uniform weight and size, making them an ideal choice for precise measurements.
To measure the rock's weight with pennies:
Place the rock on one side of the pan balance.
Place pennies on the other side of the balance until it becomes level.
Count the number of pennies used.

Multiply the number of pennies by the weight of a single penny to get the approximate weight of the rock.
Using pennies will yield the greatest level of accuracy and the least error in this scenario.

Answer:

0.13

Step-by-step explanation:

The estimated sum of 9 5/9 and 3 2/5 is approximately 13, the difference is approximately 5.84, the product is approximately 32.49, and the quotient is approximately 2.82.

To estimate the sum, difference, product, and quotient of 9 5/9 and 3 2/5, we can convert the mixed numbers into improper fractions for easier calculations.

First, let's convert 9 5/9 into an improper fraction:

9 5/9 = (9 * 9 + 5) / 9 = 86/9

Next, let's convert 3 2/5 into an improper fraction:

3 2/5 = (3 * 5 + 2) / 5 = 17/5

Now, we can perform the calculations:

Sum:

86/9 + 17/5 = (86 * 5 + 17 * 9) / (9 * 5) = 590/45

Difference:

86/9 - 17/5 = (86 * 5 - 17 * 9) / (9 * 5) = 263/45

Product:

(86/9) * (17/5) = (86 * 17) / (9 * 5) = 1462/45

Quotient:

(86/9) / (17/5) = (86 * 5) / (9 * 17) = 430/153

To simplify the fractions and estimate the results, we can approximate them to the nearest whole number or decimal:

Sum ≈ 13

Difference ≈ 5.84

Product ≈ 32.49

Quotient ≈ 2.82

Answer:

.................

Step-by-step explanation:

A = \(\frac{1}{2}h(b_{1} +b_{2} )\)

If A = 136 when \(b_{1}\) = 7 and h = 16, find \(b_{2}\)

We are given the equation that we are working with:

A = \(\frac{1}{2}h(b_{1} +b_{2} )\)

We are given certain values that the variables, in this case, are equal to:

A = 136

\(b_{1}\) = 7

h = 16

Substitute the given variables in the given equation for the corresponding numbers:

A = \(\frac{1}{2}h(b_{1} +b_{2} )\)

136 = \(\frac{1}{2}\) * 16 (7 + \(b_{2}\))

We know all the values in the equation except  \(b_{2}\). In order to find  \(b_{2}\) we must isolate it on one side of the equation

136 = 8 (7 + \(b_{2}\))

\(\frac{136}{8}\) = \(\frac{8 (7 + b_{2}) }{8}\)

17 = 7 + \(b_{2}\)

17 - 7 = 7 - 7 + \(b_{2}\)

10 =   \(b_{2}\)

If   \(b_{2}\) is equal to 10 then if we plug it back into the given equation both sides of the equation should equal each other. Remember to use PEMDAS

136 = \(\frac{1}{2}\) * 16 (7 + \(b_{2}\))

136 = \(\frac{1}{2}\) * 16 (7 + 10)

136 = \(\frac{1}{2}\) * 16 (17)

136 = 8 (17)

136 = 136

\(b_{2}\) = 10

The average value of f(x) over the interval [-14, 14] is 0.

The average value of the function f(x) = 14 - |x| over the interval [-14, 14] we need to use the formula:

\(f_{ave\) = (1/(b-a)) × integral(a to b) f(x) dx

a and b are the limits of integration.

a = -14 and b = 14.

So we have:

\(f_{ave\) = (1/(14 - (-14))) × integral(-14 to 14) (14 - |x|) dx

Simplifying the integral get:

\(f_{ave\) = (1/28) × integral(-14 to 0) (14 + x) dx + (1/28) × integral(0 to 14) (14 - x) dx

Evaluating the integrals get:

\(f_{ave\) = (1/28) × [(14x + (x²)/2)|(-14 to 0) + (-14x + (x²)/2)|(0 to 14)]

\(f_{ave\) = (1/28) × [(0 + 98) + (-196 + 98)]

\(f_{ave\) = (1/28) × 0

f_ave = 0

The probability that exactly 3 people  from that group will go to Ches Tahoe restaurant is 2.11%

The probability that at least 35 people will go to Ches Tahoe  the restaurant is -1.88.

Given that,

When you select a random person, the probability that this person will go to Ches Tahoe restaurant is 75%,

We have to determine,

You randomly select 8 people. What is the probability that exactly 3 people

from that group will go to Ches Tahoe restaurant.

You randomly select 50 people. Use the normal approximation to the binomial distribution to find the probability that at least 35 people will go to Ches Tahoe restaurant.

According to the question,

When you select a random person, the probability that this person will go to Ches Tahoe restaurant is 75%,

You randomly select 8 people.

Then,

The probability that exactly 3 people

from that group will go to Ches Tahoe restaurant is,

\(P(x) = ^nC_x \times q^x \times p^{n-x}\)

Where n = 8, x = 5, q = 1 - 0.75 = 0.25, and p = 0.75

Substitute all the values in the expression,

\(P(5) = ^8C_5 \times (0.25)^5 \times (0.75)^{8-5}\\\\P(5) = \dfrac{8!}{(8-5)!. 5!} \times 0.00097 \times (0.75)^3\\\\P(5) = \dfrac{8 \times 7 \times 6}{3 \times 2} \times 0.00097 \times 0.42\\\\P(5) = 0.2118\\\\P(5) = 2.11 \ Percent\)

The probability that exactly 3 people from that group will go to Ches Tahoe restaurant is 2.11%.

You randomly select 50 people. Use the normal approximation to the binomial  distribution

Then, the probability that at least 35 people will go to Ches Tahoe  restaurant is,

Mean for that at least 35 people will go to Ches Tahoe  restaurant is,

\(\mu = n \times p \\\\\mu = 8 \times 0.75\\\\\mu = 6\)

\(\sigma = \sqrt{n \times p \times q} \\\\\sigma = \sqrt{0.75 \times 0.25 \times 8}\\\\\sigma = \sqrt{1.5}\\\\\sigma = 0.53\)

Normal approximation to the binomial distribution is,

\(z = \dfrac{x-\mu}{\sigma}\\\\z = \dfrac{5-6}{0.53}\\\\z = \dfraac{-1}{0.53}\\\\z = -1.88\)

Answer: -1

Hope this helps lol

The simplified result is -1. The correct option is b.

Given that:

Expression, -3/2 ÷ 9/6

To solve the given expression, follow as:

Rewrite the division as multiplication by the reciprocal of the second fraction.

-3/2 ÷ 9/6 = -3/2 × (6/9)

Now, simplify the fractions:

-3/2 × (6/9) = -3/2 × (2/3)

-3/2 × (6/9) = - (3 × 2)/(2 × 3)

-3/2 × (6/9) = -6/6

Finally, the simplified expression is -6/6. However, further simplify it by dividing the numerator and denominator by their greatest common divisor, which is 6:

-6/6 = -1

So, the simplified result is -1. The correct option is b.
