Create a 90% confidence interval for the percentage of people the company contacts who may buy something.

Answer:

CI = (8.84%, 11.92%)

We are 90% Confident that the percentage of people the company contacts who may buy something is between 8.84% and 11.92%.

Step-by-step explanation:

We are given;

n = 1060

x = 110

Confidence level = 90%

Sample proportion; p^ = x/n = 110/1060

p^ = 0.1038

DF = n - 1 = 1060 - 1 = 1059

From the table attached, the critical value for a confidence level of 90% at a DF greater than 1000 is 1.645

Formula for CI is;

CI = p^ ± t√(p^(1 - p^)/n)

CI = 0.1038 ± 1.645√(0.1038(1 - 0.1038)/1060)

CI = 0.1038 ± 0.0154

CI = (0.0884, 0.1192) or

CI = (8.84%, 11.92%)

Thus, we are 90% Confident that the percentage of people the company contacts who may buy something is between 8.84% and 11.92%.

I believe this is right because rational should be positive and ir should be negative.......

Answer:

1/8", 1/4", 3/8", 5/8", 3/4", 12"

Step-by-step explanation:

First, make all of the fractions have similar denominators. We'll use eighths.

1/4 = 2/8

3/4 = 6/8

The rest are either whole numbers or already have a denominator of 8.

2/8, 6/8, 12, 1/8, 3/8, 5/8.

Rearrange.

1/8, 2/8, 3/8, 5/8, 6/8, 12.

Now we take the fractions we converted, and change them back to their original form. Then we'll have the answer.

1/8, 1/4, 3/8, 5/8, 3/4, 12.

The smallest perfect square that has three different prime numbers as factor is 900

900 = 30 * 30

Factors = 2² * 3² * 5² = 900

Answer:

110%

Step-by-step explanation:

During final exam, 172 students visited the math lab in total.

4 out of 11 were male. It means, females are 11-4 = 7. So, the percentage of female students who visited the math lab is :

[tex]F=\dfrac{7}{11}\times 172\\\\F=109.4\%\\\\=110\%[/tex]

Hence, this is the required solution.

Answer:

The axis of symmetry of a parabola is a line about which the parabola is symmetrical. When the parabola is vertical, the line of symmetry is vertical. When a quadratic function is graphed in the coordinate plane, the resulting parabola and corresponding axis of symmetry are vertical.

Step-by-step explanation:

Answer:

Step-by-step explanation:

An axis of symmetry is a line that cuts your graph into two equal parts.  In other words, the graph is symmetric about the line.

Answer:

Least is 7

Most is 12

Step-by-step explanation:

So 2 shirts for 12.

So 24

Take 24 off of both

Left with 21 to 36

21÷3 is 7

36÷3 is 12

Hope this helps

Answer:

least - $7

most - $12

Explanation:

if the price of a shirt is $12, she must have spent at least $24 on the shirts in total.

the least amount melissa could have spent on a skirt is:

($45 - $24) ÷ 3 = $7

and the most she could have spent is:

($60 - $24) ÷ 3 = $12

Answer: This lateral surface area can be calculated by multiplying the perimeter of the base by the height of the prism. For a right circular cylinder of radius r and height h, the lateral area is the area of the side surface of the cylinder: A = 2πrh.

Answer:

Its D because 2×2×2 equals 8 and they are both minus and knowing - times - makes + so it becomes 8

Answer:

B.) -1/8

Step-by-step explanation:

You flip the problem because of the negative exponent

[tex]\frac{1}{-2^3}[/tex]

This makes the exponent positive

Expand the denominator

(-2) * (-2) * (-2) = 4*(-2) = -8

1/-8 = -1/8

Answer:

B. 300

Step-by-step explanation:

Let's take the entire number as 'x'

according to the question,

x * 64% = 193

x * 64/100 = 193

x * 64 = 193 * 100

x = 19300/ 64

x = 301.5

round down to 300

Answer:

x=1, y=-5

Step-by-step explanation:

4(1)+2y=-6

2y=-10

y=-5

or

-3x-2(-5)=7

-3x=-3

x=1

did you mean (x^4 y^3 y)2 or just (x4y3y)2

Sorry did you submitted it yet?

If the given expression is (x⁴y³y)², the expression equivalent to the given expression in form of xmyn is, x⁸y⁸.

It is defined as the combination of constants and variables with mathematical operators.

It is given that the expression is,

(x⁴y³y)²

Keep the base constant and add the exponents when multiplying similar bases. Maintaining the same base while multiplying the exponents will raise a base with power to another power. When dividing two bases with similar exponents, keep the exponents of the numerator and denominator constant.

We have to represent the given expression in the form of [tex]\rm x^m y^n[/tex].

We use the expression identity as,

[tex]x^m \times x^n = x^{m+n}[/tex]

[tex]\rm = (x^m)^n \\\\ = x^{mn}[/tex]

=(x⁴y³y)²

First, solve the term present in the bracket as,

=(x⁴y⁴)²

Open the bracket we get,

=(x⁴)²(y⁴)²

=x⁸y⁸

Thus, if the given expression is (x⁴y³y)², the expression equivalent to the given expression in form of  [tex]\rm x^m y^n[/tex] is, x⁸y⁸.

Answer:

Step-by-step explanation:

7/18-2/9=7/18-4/18=3/18=1/6

Answer:

1/6.

Step-by-step explanation:

7/18−2/9=?

The fractions have unlike denominators. First, find the Least Common Denominator and rewrite the fractions with the common denominator.

LCD(7/18, 2/9) = 18

Multiply both the numerator and denominator of each fraction by the number that makes its denominator equal the LCD. This is basically multiplying each fraction by 1.

(7/18×11)−(2/9×22)=?

Complete the multiplication and the equation becomes

7/18−4/18=?

The two fractions now have like denominators so you can subtract the numerators.

Then:

7−4/18=3/18

This fraction can be reduced by dividing both the numerator and denominator by the Greatest Common Factor of 3 and 18 using

GCF(3,18) = 3

3÷3/18÷3=1/6

Therefore:

7/18−2/9=1/6
