If polygon ABCD is moved right 3 and up 2, what would the new coordinates of vertex D?

The value of an explanatory variable is 5, while the corresponding value of the response variable is 15. What would be the coord

vampirchik [111]

An explanatory variable is a type of independent variable. A response variable is a type of dependent variable. An explanatory variable is used to predict or explain differences in the response variable.

The first coordinate corresponds to independent variable and the second coordinate corresponds to dependent variable.

Since independent variable takes value 5 and dependent variable takes value 15, then the point (5,15) would be the point when plotted on a scatterplot.

Answer: correct choice D

What is the circumference of a dinner plate with a radious of 4.5 inches

____ [38]

Answer:

28.27 inches

Step-by-step explanation:

-Circumference of a circle is calculated using the formula:

$C=\pi D\\\\=2\pi r$

#Substitute for radius in the formula to solve for C:

$C=2\pi r\\\\=2\pi \times 4.5 \\\\=28.27 \ in$

Hence, the plate's circumference is 28.27 inches

According to a study conducted in 2015, 18% of shoppers said that they prefer to buy generic instead of name-brand products. Sup

Verizon [17]

Answer:

There is evidence to said that the proportion of all shoppers who currently prefer to buy generic instead of name-brand products is higher than 0.18

Step-by-step explanation:

First, we need to define the null and alternative hypothesis as:

H0: p = 0.18

H1: p > 0.18

Where p is the proportion of shoppers that said that they prefer to buy generic instead of name-brand products.

Then, we can calculated the test statistic using the following equation:

$z=\frac{p'-p}{\sqrt{\frac{p(1-p)}{n} } }$

Where p' is the proportion of the sample and n is the size of the sample.

Replacing p by 0.18, p' by 0.21 (315/1500 = 0.21) and n by 1500, we get:

$z=\frac{0.21-0.18}{\sqrt{\frac{0.18(1-0.18)}{1500} } }=3.02$

So, using the standard normal table, the p-value is calculated as:

p-value = P(z>3.02) = 0.0013

Additionally, At a 5% significance level, the critical value is the z value that let 5% on the right tail, so it is calculated as:

P(Z>z) = 0.05

Critical Value = 1.64

Finally, taking into account that the 5% significance level is higher than the p-value and the critical value is higher than the test statistic, we reject the null hypothesis and there is evidence to said that the proportion of all shoppers who currently prefer to buy generic instead of name-brand products is higher than 0.18

Can someone help with the polynomials? Please

kolbaska11 [484]

Answer:

22x^2 -10xy + 12x

Step-by-step explanation:

To add and subtract polynomials, combine only like terms. When doing it vertically, stack polynomials and line up the same bases and exponents. Once this is done, simply add and subtract the coefficients.

10x^2 + 12xy + 4x

+ 12x^2 -22xy + 8x

_________________

22x^2 -10xy + 12x

Here we added 10 + 12 = 22, 12 + -22 = -10 and 4 + 8 = 12.
