Answer:

Step-by-step explanation:

First we will take the LCM of 2 and 5

It's 10

so 1/2 × 5/5 = 5/10

2/5 × 2/2 = 4/10

5/10 y - 4/10 y = 1/10 y

Hope this helps

plz mark as brainliest!!!!

Step-by-step explanation:

1/2y - 2/5y

= 5/10y - 4/10y

= (5/10-4/10) y

=1/10y

9(k − 2) = 3(k + 4) What’s the answer

butalik [34]

9(k-2)=3(k-4)

We simplify the equation to the form, which is simple to understand
9(k-2)=3(k-4)

Reorder the terms in parentheses
+(+9k-18)=3*(k-4)

Remove unnecessary parentheses
+9k-18=+3+*(+k-4+)

Reorder the terms in parentheses
+9k-18=+(+3k-12)

Remove unnecessary parentheses
+9k-18=+3k-12

We move all terms containing k to the left and all other terms to the right.
+9k-3k=-12+18

We simplify left and right side of the equation.
+6k=+6

We divide both sides of the equation by 6 to get k.
k=1

Manny is deciding between two packages of yogurt. YoFruit costs $4.48 for 16 ounces. Yummy Yogurt costs $2.64 for 8 ounces. How

Y_Kistochka [10]

Answer:

16 is double 8, so just double the price: 2.64 x 2= $5.28

then, subtract to find the dufference: 5.28 - 4.48= $.80

then, divide that by the oz:

.80/16= 5 cents per ounce

Please explain this problem. I don't know what its asking, or what to do.

matrenka [14]

The answers are x=4 and y=323/2

1) 40/2x-3=8

Multiply both sides by 2x-3 to get rid of fraction

40= 8(2x-3)

Distribute 8

40= 16x-24

Add 24 to both sides

64=16x

Divide by 16

4=x

2) 2y-3/40=8

Multiply both sides by 40 to red rod of fraction

2y-3=320

Add 3 to both sides

2y= 323

Divide by 2

Y=323/2

Now just describe the differences in solving them

FYI / means fraction, right after the slash is bottom of fraction

Think about a population proportion that you may be interested in and propose a confidence interval problem for this parameter.

o-na [289]

Answer: The confidence interval would be (0.2928,0.3672).

Step-by-step explanation:

Since we have given that

Total number of vehicles = 432

Number of SUVs sold = 142

So, it becomes,

$\hat{p}=\dfrac{x}{n}=\dfrac{142}{432}=0.33$

At 90% confidence interval,

z = 1.645

So, the confidence interval would be

$\hat{p}\pm z\sqrt{\dfrac{\hat{p}(1-\hat{p})}{n}}\\\\=0.33\pm 1.645\sqrt{\dfrac{0.33\times 0.67}{432}}\\\\=0.33\pm 0.0372\\\\=(0.33-0.0372,0.33+0.0372)\\\\=(0.2928,0.3672)$

Hence, the confidence interval would be (0.2928,0.3672).
