Many consumers pay careful attention to stated nutritional contents on packaged foods when making purchases. It is therefore imp

ortant that the information on packages be accurate. The null hypothesis is that the stated calorie content on a frozen dinner package is 240. A random sample of 12 frozen dinners of a certain type was selected and used to test this null hypothesis. Which of the following describes a Type I​ error?
A. We conclude that the mean calorie content of the dinners is 240 when it actually
is different from 240.
B. We conclude that the mean calorie content of the dinners is not​ 240, when it
actually is 240.
C. We conclude that the mean calorie content of the dinners is​ 240, when it actually
is 240.
D. We conclude that the mean calorie content of the dinners is not 240 when it
actually is different from 240.

A baseball will reach heighth feet artert seconds, as
romanna [79]

Answer:

1 and 37/8 feet

Step-by-step explanation:

We set h(t) to 76 because we want to know when the ball will be at 76 feet high.

So, we have 76=-16t^2+90t+2. When we subtract 76 from both sides, we get -16t^2+90t-74=0, and when you mutiply the equation by -1 (so that x^2 has a positive coefficient, which makes things easier), we get 16t^2-90t+74=0.

We notice that each separate monomial has a common factor, 2, so we can take that out and make it 2(8t^2-45t+37) = 0. Factoring the quantity in the parentheses gives us 2(t-1)(8t-37) = 0.

Using Zero Product Property, we can set the two factors in parentheses to 0 (the 2 isn't really relevant so we don't need to worry about it). This gives us t-1=0 and 8t-37=0. Solving these two equations gives us t = 1 foot or t = 37/8 feet.

1 Draw the Venn diagram below. Write the numbers 8, 9, 10, 11, 12 and 13 in the correct places on your Venn diagram. multiples o
iragen [17]

Venn diagram is the representation of set in a graphical form

<em>See attachment for the set of multiples of 2, 13, 3 and 6 </em>

Given

Numbers = \{8,9,10,11,12,13\}

Let

<em />A \to<em> Multiples of 2</em>

<em />B \to<em> Multiples of 8</em>

<em />C \to<em> Multiples of 6</em>

<em />D \to<em> Multiples of 13</em>

<em />

First, we split the numbers in set of the given multiples

A: \{8, 10, 12\}

B = \{8\}

C =\{12\}

D = \{13\}

Digit 9 does not belong to any of these set

<em />

<em>Set B and set C are proper subsets of set A.</em>

This means that sets B and C will be inside set A in the Venn diagram

So, we have:

A = \{B,10,C\}

Since 9 does not belong to any of the sets, it will not be inside any of sets A, B, C or D

See attachment for the required Venn diagram

Please Help Me!!! (15 points)
Olenka [21]

Answer:

Step-by-step explanation:

y = 5x + 1

Table for input-output values is,

x        0         1           2           3

y        1          6          11          16          

Now we can plot these points to get the graph.

y = x + 2

Table for the Input-output values,

x       0         1           2          3

y       2         3          4          5

We can get the graph as attached.
