Answer:

w= -52

Step-by-step explanation:

We simplify the equation to the form, which is simple to understand

15-w/4=28

Simplifying:

15-0.25w=28

We move all terms containing w to the left and all other terms to the right.

-0.25w=+28-15

We simplify left and right side of the equation.

-0.25w=+13

We divide both sides of the equation by -0.25 to get w.

w= -52

Hope it Helps :) !!

What is the enlargement ratio if you enlarge the figure to have a width of 16 units and length of 12 units

Fantom [35]

Answer:

The enlargement ratio is 3:4

Step-by-step explanation:

We are given

a width of 16 units and length of 12 units

so,

$W=16$

and

$L=12$

now, we can find enlargement ratio

we can use formula

enlargement ratio = (length)/(width)

$=\frac{L}{W}$

now, we can plug values

$=\frac{12}{16}$

now, we can simplify it

$=\frac{3}{4}$

So,

The enlargement ratio is 3:4

ayme built a box in the shape of a rectangular prism with the dimensions shown. What is the volume of the box, in cubic inches?

Snezhnost [94]

Answer:

$64(in)^{3}$

Step-by-step explanation:

The volume of a box is equal to the length l times the width w times the height h.

$(lenght) \times (width) \times (height)$

Substitute the values of the length l=8, the width w=2, and the height h=4 into the formula.

$8 \times 2 \times 4$

Multiply 8 by 2.

$16 \times 4$

Multiply 16 by 4.

$64 {in}^{3}$

Hence, the volume of the rectangle prism is 64(in)³.

Consider two independent tosses of a fair coin. Let A be the event that the first toss results in heads, let B be the event that

aliina [53]

Answer with Step-by-step explanation:

We are given that two independent tosses of a fair coin.

Sample space={HH,HT,TH,TT}

We have to find that A, B and C are pairwise independent.

According to question

A={HH,HT}

B={HH,TH}

C={TT,HH}

$A\cap B=$ {HH}

$B\cap C$ ={HH}

$A\cap C$ ={HH}

P(E)= $\frac{number\;of\;favorable\;cases}{total\;number\;of\;cases}$

Using the formula

Then, we get

Total number of cases=4

Number of favorable cases to event A=2

$P(A)=\frac{2}{4}=\frac{1}{2}$

Number of favorable cases to event B=2

Number of favorable cases to event C=2

$P(B)=\frac{2}{4}=\frac{1}{2}$

$P(C)=\frac{2}{4}=\frac{1}{2}$

If the two events A and B are independent then

$P(A)\cdot P(B)=P(A\cap B)$

$P(A\cap)=\frac{1}{4}$

$P(B\cap C)=\frac{1}{4}$

$P(A\cap C)=\frac{1}{4}$

$P(A)\cdot P(B)=\frac{1}{2}\cdot \frac{1}{2}=\frac{1}{4}$

$P(B)\cdot P(C)=\frac{1}{4}$

$P(A)\cdot P(C)=\frac{1}{4}$

$P(A)\cdot P(B)=P(A\cap B)$

Therefore, A and B are independent

$P(B)\cdot P(C)=P(B\cap C)$

Therefore, B and C are independent

$P(A\cap C)=P(A)\cdot P(C)$

Therefore, A and C are independent.

Hence, A, B and C are pairwise independent.
