Answer:

(a)

Step-by-step explanation:

Given

See attachment for sets A and B

Required

The true statement about both sets

First, we calculate the typical values (mean) of set A and set B.

This is calculated as:

Mean = \frac{\sum fx}{\sum f}

For A:

A= \frac{0*1+2*1+5*1+6*1+7*1}{1+1+1+1+1}

A= \frac{20}{5}

A =4

For B:

B = \frac{7 * 1 + 8 *1 + 9 * 2 + 10 * 1}{1+1+2+1}

B = \frac{43}{5}

B = 8.6

<em>Here, we can conclude that B has a larger typical value</em>

Next calculate the spread (range) of sets A and B

This is calculated as:

Range = Highest -Least

For A:

A = 7 - 0

A = 7

For B

B=10 - 7

B = 3

<em>Here, we can conclude that A has a larger spread.</em>

<em></em>

<em>Hence, (a) is true</em>

The equation y = 5.50x represents the cost y (in dollars) for x visits to the
mr Goodwill [35]

In Graph x-axis represents number of visits and y-axis represents cost.

As graph comes up to be a linear one, so we can clearly say that cost is increasing linearly in multiples of 5.5 with increase in number of visits.

Example :

If museum is visited once then cost (y) = 5.5 x 1 = 5.5

If museum is visited twice then cost (y) = 5.5 x 2 = 11

If museum is visited thrice then cost (y) = 5.5 x 3 = 16.5

... cost (y) goes on in creasing when number of visits (x) increase with multiples of 5.5

Tim wrote 16 as (-2) squared 4. Is he correct?
stepladder [879]

Answer:

Yes, Tim was correct.

Step-by-step explanation:

It is given that Tim wrote 16 as (-2) squared 4. It means

16=(-2)^4

We need to check whether he is correct option not.

LHS=16

RHS=(-2)^4

RHS=(-2)\times (-2)\times (-2)\times (-2)

RHS=4\times 4

RHS=16

RHS=LHS

Since LHS is equal to the RHS, therefore the Tim was correct.

the perimeter of a rectangular garden is 100 feet the length of the garden is 8 feet longer twice the width
KonstantinChe [14]
Start with this - l = 2w+8
2*(l+w) = P
2*(2w+8 + w) = 100
(2w+8 + w)  = 50
2w+w = 42
3w = 14
