Answer:

the answer is 0

Step-by-step explanation:

well - 3 plus 3 would just by 0 because if the number with the negative is the biggest then the answer is negative but if the positive number is the biggest then the answer would be positive because there is not a bigger number it would be 0 because 3 and -3 have pretty much the same value other then them being negative and positive

Evaluate the integral Integral from left parenthesis 2 comma 1 comma 2 right parenthesis to left parenthesis 6 comma 7 comma neg

White raven [17]

ANSWER

-9

EXPLANATION

We want to evaluate the line integral:

$\int_{(2,1,2)}^{(6,7,-5)}ydx+xdy+7dz$

The parametric equations for the line segment from (2,1,2) to (6,7,-5) is

$x = 2 + 4t$

$y= 1 + 6t$

$z= 2 - 7t$

This implies that:

$dx = 4dt$

$dy = 6dt$

$dz = - 7dt$

Our integral now becomes:

$\int_{0}^{1} (1 + 6t)(4)+(2 + 4t)(6) + 7( - 7)dt$

We simplify to get:

$\int_{0}^{1} 48t - 33dt$

This integral evaluates to:

$\int_{0}^{1} 48t - 33dt = - 9$

steposvetlana [31]

Answer:

0.486

Step-by-step explanation:

Given that a box contains recipes from five categories.

The following table shows the possible categories and the associated probability for a recipe randomly chosen.

Genre Probability

Main Dish 0.421

Appetizer 0.210

Desert 0.103

Salad 0.173

Vegetable 0.093

This is a proper probability distribution function because total prob =1 and also each prob lies between 0 and 1.

The probability of randomly selecting anything but a vegetable or a main dish category

= Prob of selecting appetizer or dessert or salad

= $0.210+0.103+0.173\\=0.486$

If a normal distribution has a mean of 44 and a standard deviation of 8, what is the zscore for a value of 50

Misha Larkins [42]

Answer:

0.75

Step-by-step explanation:

Z-score tells the no. of standard deviations a data point is from the mean.

the formula for z score is given by

z-score= (data value - mean) / standard deviation

Given:

mean=44

standard deviation= 8

data point=50

putting the values of mean(44), standard deviation(8) and given data value(50) in the above equation

z-score= (50-44)/8

= 6/8

=0.75 !
