The bases of a right prism are isosceles trapezoids with bases of 10 ft and 18 ft

likoan [24]

Answer:

540 ft^2.

Step-by-step explanation:

The area of the trapezoid = h/2 (10 + 18) = 14h.

By Pythagoras the height h = √(5^2 - 4^2) = 3.

So the area of the 2 trapezoidal bases = 2 * 14*3

= 84 ft^2.

Now we calculate the area of the four lateral rectangular sides:

= 10*12 + 18*12 + 2*5*12

= 456 ft^2.

Total area = 456 + 54

= 540 ft^2.

The sum of three numbers is 62. The second number is equal to the first number diminished by 4. The third number is four times t

alexdok [17]

Let the three numbers be x, y and z respectively, then
x + y + z = 62 . . . (1)
y = x - 4 . . . (2)
z = 4x . . . (3)

The above three expressions could be used to represent the numbers.

Solving the three equations, putting (2) and (3) into (1) gives
x + x - 4 + 4x = 62
6x - 4 = 62
6x = 62 + 4 = 66
x = 66/6 = 11
x = 11.
y = 11 - 4 = 7
z = 4(11) = 44

x = 11, y = 7, z = 44.

Write an equation of the line that passes through the given points (1 , 1.5) and (2, 3.5)

Nitella [24]

Answer:

y=2x-0.5

Step-by-step explanation:

typically, the equation of the line is written in slope intercept form, which is y=mx+b, where m is the slope and b is the y intercept

first, we need to find the slope (m) of the line

the formula for slope calculated from two points is given as (y2-y1)/(x2-x1)

we have two points: (1,1.5) and (2,3.5) and we can label them

x1=1

y1=1.5

x2=2

y2=3.5

now plug into the formula:

m=(3.5-1.5)/(2-1)

m=2/1

m=2

the slope of the line is 2

here's our equation so far:

y=2x+b

now we need to find b

since the line will pass through the points (1, 1.5) and (2, 3.5), we can plug either one of them into the equation to solve for

Let's use (1, 1.5)

substitute 1.5 as y and 1 as x

1.5=2(1)+b

1.5=2+b

subtract 2 from both sides

-0.5=b

therefore, our equation is:

y=2x-0.5

hope this helps!

Use the given qualitative data to construct the relative frequency distribution.

ikadub [295]

Answer:

Category Relative Frequency

male survivors 17.3%

males who died 63.7 %

Female survivors 15.1 %

Females who died 3.8%

Step-by-step explanation:

The relative frequency is the proportion of the number of times the event occurs to the total number of trials.

Given : Total people on ship = 2274

Number of male survivors = 394

⇒ Relative Frequency of male survivors = $\dfrac{394}{2274}$

In percent , $\dfrac{394}{2274}\times100\approx17.3\%$

Number of males who died =1449

⇒ Relative Frequency of male who died = $\dfrac{1449}{2274}$

In percent , $\dfrac{1449}{2274}\times100\approx63.7\%$

Number of female survivors =344

⇒ Relative Frequency of female survivors = $\dfrac{344}{2274}$

In percent , $\dfrac{344}{2274}\times100\approx15.1\%$

Number of females who died = 87

⇒ Relative Frequency of females who died = $\dfrac{87}{2274}$

In percent , $\dfrac{87}{2274}\times100\approx3.8\%$

Hence, the complete table would be :

Category Relative Frequency

male survivors 17.3%

males who died 63.7 %

Female survivors 15.1 %

Females who died 3.8%
