What are the values of each Halloween icon?

Answer: its a little blurry not to be rood :c

Step-by-step explanation:

Critical value for a 97% confidence interval. For a large sample size, it is approximately 1.96.

(a) In this question, the following notations can be used: p1: Proportion of all male registered voters who voted in the last presidential election in country Y. p2: Proportion of all female registered voters who voted in the last presidential election in country Y. n1: Sample size of the male registered voters. n2: Sample size of the female registered voters. (b) To construct a 97% confidence interval for the difference between the proportion of all male and all female registered voters who were not voted in the last presidential election in country Y, we can use the following steps.

Calculate the sample proportions: phat1: Proportion of male registered voters who voted = 68% = 0.68 ;phat2: Proportion of female registered voters who voted = 65% = 0.65 .Calculate the standard errors for each proportion: SE1 = sqrt((phat1 * (1 - phat1)) / n1); SE2 = sqrt((phat2 * (1 - phat2)) / n2). Calculate the margin of error: ME = Z * sqrt((SE1^2) + (SE2^2)) ;  Z: Critical value for a 97% confidence interval. For a large sample size, it is approximately 1.96. Calculate the lower and upper bounds of the confidence interval: Lower bound = (phat1 -phat2) - ME; Upper bound = (phat1 - phat2) + ME. The 97% confidence interval for the difference between the proportion of all male and all female registered voters who were not voted in the last presidential election in country Y can be expressed using the notations as [ (phat1 - phat2) - ME, (phat1 - phat2) + ME ].

Number of bowls that Laura can make with 10lbs of clay is 16

To find out how many bowls Laura can make, we need to divide the amount of clay she has by the amount of clay needed to make one bowl.

Let's start by converting the fraction 3/5 into a decimal:

3/5 = 0.6

This means that Laura needs 0.6 lbs of clay to make one bowl.

Now we can divide the total amount of clay Laura has by the amount of clay needed for one bowl:

10 ÷ 0.6 = 16.67

Laura can make 16 complete bowls with 10 lbs of clay, and she will have some clay left over (0.07 lbs to be exact) that is not enough to make another full bowl.

What is a cricle ?

A circle is a basic 2D shape measured by its radius. A circle divides the plane into two areas: interior and exterior. Similar to line type. Imagine a line segment bending until the ends connect. Arrange the loops so that they form a perfect circle.

we know that,

arc length = radius *  central angle (in radians)

and central angle (in radians) = arc length / radius

by substituting the given values

arc length = 7.2

radius=9

we get,

central angle (in radians) = 7.2 / 9

=0.8 radians

Hence , the central angle = 0.8 radians

The answer of the given question based on differential equation is ,

y² = (3/13)(C - x⁴)

An equation is mathematical statement that indicates  equality of two expressions. It consists of variables, constants, and mathematical operations like addition, subtraction, multiplication, division, exponentiation, etc. An equation can be written in different forms depending on the type of equation, like linear, quadratic, polynomial, trigonometric, exponential, or logarithmic.

The given differential equation is:

dy/dx = 4x³/(3x² + 13y²)

To find  general solution, we need to separate variables and integrate both sides:

(3x² + 13y²) dy = 4x³ dx

Integrating both sides:

∫(3x² + 13y²) dy = ∫4x³ dx

Simplifying and solving the integrals:

x⁴ + (13/3)y³ = x⁴ + C

where C is the constant of integration.

Therefore, the general solution to the given differential equation is:

y² = (3/13)(C - x⁴)

where C is an arbitrary constant.

Answer: C

Step-by-step explanation:

The probability that sample is greater than 418 will be is 6.533.

Probability is the occurence of likely events. It is the area of mathematics that deals with numerical estimates of the likelihood that an event will occur or that a statement is true.

Here we have

\(\mu=397.64,n=40,\sigma=20\)

According to central limit theorem, the sampling distribution of mean will be normal with mean

\(\mu_{\bar{x}}=\mu=397.64\)

and standard deviation

\(\sigma_{\bar{x}}=\frac{\sigma}{\sqrt{n}}=\frac{20}{\sqrt{40}}=3.1623\)

The z-score for\(\bar{x}=418\) is

\(z=\frac{\bar{x}-\mu_{\bar{x}}}{\sigma_{\bar{x}}}=\frac{418-397.34}{3.1623}=6.533\)

Therefore, the probability that sample is greater than 418 will be

Answer:

The equation is: 120 - 4x = 92. There are 7  incorrect answers.

Step-by-step explanation:

Comparing the means of the two samples, we find that the difference between the means is significant. Therefore, we can reject the claim and conclude that male and female high school students have different exam scores.

To perform the two-sample t-test, we first calculate the standard error of the difference between the means using the formula:

SE = sqrt((s1^2 / n1) + (s2^2 / n2))

Where s1 and s2 are the population standard deviations of the male and female students respectively, and n1 and n2 are the sample sizes. Plugging in the values, we have:

SE = sqrt((47^2 / 49) + (4.3^2 / 53))

Next, we calculate the t-statistic using the formula:

t = (x1 - x2) / SE

Where x1 and x2 are the sample means. Plugging in the values, we have:

t = (239 - 21.1) / SE

We can then compare the t-value to the critical t-value at α = 0.01 with degrees of freedom equal to the sum of the sample sizes minus 2. If the t-value exceeds the critical t-value, we reject the null hypothesis.

In this case, the t-value is calculated and compared to the critical t-value using the provided standard normal distribution table. Since the t-value exceeds the critical t-value, we can reject the claim that male and female high school students have equal exam scores.

Therefore, the correct answer is:

B. Male and female high school students have different exam scores.

Answer:

Degrees = Radians x 180/π

or

Degrees = 57.2958  x radians

Step-by-step explanation:

1 radian = 180/π degrees

1 radian = 57.2958 degrees

Multiply radians by this factor of 57.2958  to get the equivalent measure in degrees

π radians = 180°

2π radians = 360° which is the number of degrees in a circle

For anything greater than 2π radians you will have to subtract 360°

For example, 7 radians using the formula is 7 x (57.2958  ) ≈ 401.07°

But this still falls in the first quadrant, so relative to the x-axis it is
401.07 - 360 = 41.07°

In the chi-square test for two-way tables, the null hypothesis (H0) typically claims that there is no association or relationship between the two categorical variables being analyzed. It states that any observed differences or associations between the variables in the two-way table are due to chance or random variation.

More specifically, the null hypothesis assumes that the observed frequencies in the two-way table are equal to the expected frequencies that would be observed if the variables were independent of each other. It suggests that any deviation from independence in the observed frequencies is purely due to sampling variability.

The alternative hypothesis (Ha), on the other hand, asserts that there is a significant association or relationship between the two variables, indicating that the observed frequencies differ from the expected frequencies in a way that is not likely to occur by chance alone.

The chi-square test is used to assess the evidence against the null hypothesis and determine whether the observed association in the two-way table is statistically significant.

Answer:

Step-by-step explanation:

Although this problem is quite long and exhausting, it is deceptively simple.

We know that his 12-gallon fuel tank is only half full, so we know that the car needs 6 more gallons of fuel.

If he turns in the car late, he will have to pay y = 2.59x + 32.00, where x is the number of empty gallons (in this case, 6)

In this case, he will pay 2.59(6) + 32.00 = $47.54

If he turns in the car on time, he will have to pay y = 4.50x + 5.00, where x is the number of empty gallons (still 6).

In this case, he will pay 4.50(6) + 5.00 = $32.00

Using these results, we know that B must be true.
