I think the first option is correct because after taking away $28 from $50, you have $22 left over. If you know how gift cards work, then you know you cannot go over the limit ( the limit here is $22) so the “or equal to” is included. Moreover, because you can’t go over the limit with a gift card, the value of x would have to be less than or equal to $22. If you have any questions comment on my answer so I can answer them! Hope my answer helps!

Answer:

4th option

Step-by-step explanation:

She purchased a DVD for $28.

$50 - $28 = $22

1. 22 < 22

2. 22 > 22

3. 22 < 78

4. 22 > 78

I would say it would be the 4th option because she can only spend less than 78.

I can be very incorrect though, don't depend on me that much. Just make sure to think about my answer and what you would answer.

One meter is 3.28 feet, so anything shorter than that. A basketball, maybe a very young child?

The area of a rectangle is 4w - 10 square units.
podryga [215]

Area of rectangle = 2(2w - 5) is the factored form of given expression

Multiplying the length and width of a rectangle, we get the area of the rectangle

<em><u>Solution:</u></em>

Given that, area of rectangle is 4w - 10 square units

We have to factor the expression

From given,

Area of rectangle = 4w - 10

Take 2 as common factor

Area of rectangle = 2(2w - 5)

Thus the given expression is factored

<em><u>The area of rectangle is given as:</u></em>

Area\ of\ rectangle = length \times width

Area\ of\ rectangle = 2 \times (2w - 5)

Thus, multiplying the length and width of a rectangle, we get the area of the rectangle

When we multiply 2 with 2w - 5 we get the area of rectangle

From above we can say,

Length = 2 or 2w - 5

Width = 2w - 5 or 2

So when dimensions of rectangle are multiplied we get area of rectangle

The missing term in the denominator is
Margaret [11]

\frac{7^{16} }{7^{12} }= \frac{7^{16-34} }{7^{12-34} } =\frac{7^{-18} }{7^{-22} } = 2401

so the missing term in the denominator is 7^(-22)

ok done. Thank to me :>

IQ test scores are standardized to produce a normal distribution with a mean of = 100 and a standard deviation of = 15. Find the
mixas84 [53]

Answer:

0.01

Step-by-step explanation:

Using the z score formula

z = (x-μ)/σ,

where x is the raw score = 135

μ is the population mean = 100

σ is the population standard deviation = 15

z = 135 - 100/15

z = 2.33333

P-value from Z-Table:

P(x<135) = 0.99018

P(x>135) = 1 - P(x<135)

P(x > 135) = 1 - 0.99018

= 0.0098153

Approximately to 2 decimal places

= 0.01

Therefore, the proportion of the population for the following IQ score of 135 is 0.01
