To determine if the percentage of Contra Costa County residents supporting a ban is greater than the nationwide percentage reported by the Pew Research Center, we need to follow these steps.

1. Obtain the Pew Research Center's report on the nationwide percentage of people supporting a ban.
2. Gather data on the percentage of Contra Costa County residents supporting the ban. This data could come from local surveys, polls, or other relevant sources.
3. Compare the two percentages to see if the Contra Costa County percentage is greater than the nationwide percentage.

If the Contra Costa County percentage is greater than the nationwide percentage, we can be confident that a higher proportion of county residents support the ban. However, it is important to note that survey results may vary based on the sample size, methodology, and timing of the polls. To draw more accurate conclusions, it's essential to consider multiple sources of data and ensure the reliability of the information being used.

In summary, to confidently assert that the percentage of Contra Costa County residents supporting a ban is greater than the nationwide percentage, we must gather local data and compare it to the Pew Research Center's report. The reliability of this conclusion depends on the accuracy and representativeness of the data used.

the area under the standard normal curve between z = -0.89 and z = 2.56 is approximately 0.8088 when rounded to four decimal places.

To find the area under the standard normal curve between z = -0.89 and z = 2.56, we can use a standard normal distribution table or a calculator.

Using a standard normal distribution table, we look up the values corresponding to z = -0.89 and z = 2.56.

The area to the left of z = -0.89 is given by the cumulative probability P(Z < -0.89). Looking up this value in the table, we find it to be approximately 0.1867.

The area to the left of z = 2.56 is given by the cumulative probability P(Z < 2.56). Looking up this value in the table, we find it to be approximately 0.9955.

To find the area between these two z-values, we subtract the cumulative probability of the lower bound from the cumulative probability of the upper bound:

Area = P(-0.89 < Z < 2.56) = P(Z < 2.56) - P(Z < -0.89)

= 0.9955 - 0.1867

= 0.8088

Therefore, the area under the standard normal curve between z = -0.89 and z = 2.56 is approximately 0.8088 when rounded to four decimal places.

When two variable quantities have a constant ratio their relationship is called a direct variation. The formula for direct variation is y = kx, where k is called the constant of variation.  If we know k we can find y given x or we can find x given y.

If we solve the equation y = kx for k, we get k = y/x.  If we replace the variables x and y with the actual values from the problem we have:

k = 25/5, which is 5.  

Now we can substitute this value for k into the equation y = kx to find y when x is 7:

y = (5) (7)

y = 35

The volume of the solid generated by revolving the region bounded by the graphs of the equations y = x, y = 4, and x = 0 about the line y = 5 is (32π/3) cubic units.

To find the volume of the solid, we can use the method of cylindrical shells. The region bounded by the given equations is a trapezoidal region with vertices (0, 4), (0, 0), (4, 4), and (4, 0). When revolved about the line y = 5, it forms a solid with a cylindrical shape.

The height of each cylindrical shell is given by the difference between the y-coordinate of the line y = 5 and the equation y = x, which is 5 - x. The radius of each cylindrical shell is the distance from the x-axis to the line x = 0, which is simply x.

Integrating the volume of each cylindrical shell from x = 0 to x = 4, and using the formula for the volume of a cylindrical shell, we obtain:

V = ∫[0 to 4] 2πx(5 - x) dx

Evaluating this integral gives V = (32π/3) cubic units.

Therefore, the volume of the solid generated by revolving the given region about the line y = 5 is (32π/3) cubic units.

As per the greedy algorithm, the change of the cent is three quarters, two dimes, and two pennies. (option c).

The greedy algorithm is a simple algorithm that always chooses the largest possible coin denomination to make change, until the amount owed is zero. Let's look at some examples:

To make change for 97 cents using the greedy algorithm, we start by choosing the largest coin denomination, which is a quarter. We can use three quarters, and we have 22 cents remaining.

Now, we use the largest coin denomination again, which is a penny. We can use two pennies to make up the remaining 2 cents. So, the answer is three quarters, two dimes, and two pennies.

We are given only two sample space 3,6

The probability of selecting either 3 or 6 is

0.5, 0.5

a. The function h(x) is undefined for x = 0 and x = ±√7.

b. These values correspond to vertical asymptotes for the function h(x).

c. The function h(x) has a hole at x = 0.

d. The limit of h(x) as x approaches 0 is either positive infinity or negative infinity, depending on the direction from which x approaches 0.

A function is an association between inputs in which each input has a unique link to one or more outputs.

To determine the behavior of the function h(x) = (4x² + 9x²) / (-x³ + 7x), let's analyze each question separately:

i) The function h(x) is undefined when the denominator equals zero since division by zero is undefined. Thus, we need to find the value(s) of x that make the denominator, (-x³ + 7x), equal to zero.

-x³ + 7x = 0

To find the values, we can factor out an x:

x(-x² + 7) = 0

From this equation, we see that x = 0 is a solution, but we also need to find the values that make -x² + 7 equal to zero:

-x² + 7 = 0

x² = 7

x = ±√7

So, the function h(x) is undefined for x = 0 and x = ±√7.

ii)  A vertical asymptote occurs when the denominator approaches zero, but the numerator does not. In other words, we need to find the values of x that make the denominator, (-x³ + 7x), equal to zero.

From the previous analysis, we found that x = 0 and x = ±√7 make the denominator zero. Therefore, these values correspond to vertical asymptotes for the function h(x).

iii) A hole in the function occurs when both the numerator and denominator have a common factor that cancels out. To find the values of x that create a hole, we need to factor the numerator and denominator.

Numerator: 4x² + 9x² = 13x²

Denominator: -x³ + 7x = x(-x² + 7)

We can see that x is a common factor that can be canceled out:

h(x) = (13x²) / (x(-x² + 7))

Therefore, the function h(x) has a hole at x = 0.

iv) To simplify the expression and find the limit of h(x) as x approaches 0, we can factor out common terms from both the numerator and denominator.

h(x) = (4x² + 9x²) / (-x³ + 7x)

We can factor out x² from the numerator:

h(x) = (4x² + 9x²) / (-x³ + 7x)

    = (13x²) / (-x³ + 7x)

Now, we can cancel out x² from both the numerator and denominator:

h(x) = (13x²) / (-x³ + 7x)

    = (13) / (-x + 7/x²)

Next, we substitute x = 0 into the simplified expression:

lim x→0 (13) / (-x + 7/x²)

Now, we can evaluate the limit by substituting x = 0 directly into the expression:

lim x→0 (13) / (-0 + 7/0²)

    = 13 / (-0 + 7/0)

    = 13 / (-0 + ∞)

    = 13 / ∞

The result is an indeterminate form of 13/∞. In this case, we can interpret it as the limit approaching positive or negative infinity. Therefore, the limit of h(x) as x approaches 0 is either positive infinity or negative infinity, depending on the direction from which x approaches 0.

Answer:

The cost per person varies inversely with the number of people, so y = k/x for some fixed number k.

"It costs $90 each for five people", meaning that x = 5 and y = 90 pair up. Plug these values in and solve for k.

y = k/x

90 = k/5

90*5 = k

450 = k

k = 450

Therefore the equation updates to y = 450/x

Now we want to know how many passengers there are (x) when the cost per person is y = 56.25

Let's find out:

y = 450/x

56.25 = 450/x ... replace y with 56.25

56.25x = 450

x = 450/56.25

x = 8

If you have 8 people, then it costs $56.25 per person.

side note: the total cost is $450 which is the value of k we found earlier. Divide 450 over 8 and you should get 56.25 exactly. Optionally you can turn y = k/x into x*y = k form. So the equation y = 450/x is the same as x*y = 450.

If the perimeter of a rectangular living room is 38 meters, the length of the living room is 105 meters.

The perimeter of a rectangle is the sum of the lengths of all its sides. Let's denote the length of the living room as "L". The formula for the perimeter of a rectangle is:

Perimeter = 2(length + width)

We know that the width of the living room is 9 meters, and the perimeter is 38 meters. Substituting these values in the formula, we get:

38 = 2(L + 9)

Dividing both sides by 2, we get:

Create a frequency distribution with 10 intervals for 60 cases that range in score from 4 to 84, each interval will have an approximate width of 8 units.

To determine the width of each interval in a frequency distribution, we need to calculate the range of the data and divide it by the desired number of intervals.

Given that the scores range from 4 to 84, the range of the data is 84 - 4 = 80 units.

To distribute these 80 units into 10 intervals, we divide the range by the number of intervals:

Interval width = Range / Number of Intervals

Interval width = 80 / 10 = 8 units

Therefore, each interval in the frequency distribution will have an approximate width of 8 units.

In practice, it's important to note that the width of intervals can be adjusted slightly depending on the specific requirements or characteristics of the data.
