They’re not equivalent because 18 divided by 6 is not the same as the quotient of 8 divided by 4

To get from 6 to 18 you multiply by 3 to get from 6 to 4 you only multiply by 2

Hey fellas, giving brainliest and a lot of points to who gets this correct​
Ainat [17]

Answer:

7\frac{1}{12} or \frac{85}{12}

Step-by-step explanation:

total boxes = Jills boxes + Mikes boxes

total boxes = 5\frac{1}{3} +1\frac{3}{4}

                   = \frac{16}{3} + \frac{7}{4}

                   = \frac{64+21}{12}

                   = \frac{85}{12}

                   = 7\frac{1}{12}

The equation that represents the canned goods order is 24x+64y=384
Lubov Fominskaja [6]

The x-intercept is (16, 0) and y- intercept is (0, 6).

<h3>What is intercept?</h3>

The x-intercept is the point where a line crosses the x-axis, and the y-intercept is the point where a line crosses the y-axis.

Given: 24x+64y=384

For y- intercept, put x=0

Then,

24*0+64y=384

64y= 384

y= 6

Now, for x- intercept put y=0

Then,

24x+64*0=384

24x= 384

x= 15

Hence, the x-intercept is (16, 0) and y- intercept is (0, 6).

2) Brian purchased pens for 75 cents each and pencils for 40 cents each he bought total of 22 writing utensils for $11.95. How m
d1i1m1o1n [39]

Answer:

13 pencils.

Step-by-step explanation:

Let x be the pens and y be the pencils

Given:

Brian purchased pens for 75 cents each and pencils for 40 cents each he bought total of 22 writing utensils for $11.95.

Total pens and pencils is 22

So, x+y=22----------------(1)

And he bought all utensils for $11.95. and each pen for 75 cents and pencils for 40 cents.

0.75x+0.40y=11.95------------(2)

solve equation 1 and equation 2 for x and y.

From equation 1.

x+y=22

y=22-x----------------(3)

put y value in equation 2.

0.75x+0.4(22-x)=11.95

0.75x+0.4\times 22-0.4x=11.95

0.75x+8.8-0.4x=11.95

0.75x-0.4x=11.95-8.8

0.35x=3.15

x=\frac{3.15}{0.35}

x=9

Now substitute x value in equation 3.

y=22-9

y=13

So, he buy 13 pencils.

The height distribution of NBA players follows a normal distribution with a mean of 79 inches and standard deviation of 3.5 inch
Shtirlitz [24]

Answer:

The probability will be "0.0111".

Step-by-step explanation:

The given values are:

Mean,

\mu = 79

Standard deviation,

\sigma = 3.5

Now,

⇒ \sigma\bar x = \frac{\sigma}{\sqrt n}

         =   \frac{3.5}{\sqrt 16}

         =0.875

⇒ P(\bar x > 81) = 1 - P(\bar x < 81)

So,

= 1 - P{\frac{(\bar x - \mu \bar x )}{ \sigma \bar x}  < \frac{(81 - 79) }{0.875} ]

= 1 - P(z < 2.2857)

= 0.0111
