Answer:

d is equal to 4

Step-by-step explanation:

to do this problem divide both sides by 0.5 to isolate the variable d

0.5d = 2

d = 4

Answer:

4

Step-by-step explanation:

You want to get d all by its self. So, divide both sides by 0.5.

2 ÷ 0.5 = 4

d ÷ 0.5 = d

Then you get:

d = 4

Hope this helps!

Answer:

1 < a < 2

Step-by-step explanation:

8 < 2 (a+3) <10

8 < 2a+6 < 10 (Simplify all parts of the inequality)

8+ −6 < 2a +6+ −6 < 10+ −6 (Add -6 to all parts)

2 < 2a < 4

2/2 < 2a/2 < 4/2 (Divide all parts by 2)

=1 < a < 2

Answer:

There is significant evidence to support that more than 3% of the population of the city got infected by the virus.

Step-by-step explanation:

x = 40 ; n = 1000

phat = x / n = 40 / 1000 = 0.04 = 4%

H0 : p = 0.3

H1 : p > 0.3

The test statistic :

(Phat - P) ÷ √(p(1 - p) / n)

1 - p = 1 - 0.3 = 0.7

(0.4 - 0.3) ÷ √(0.3(0.7) / 1000)

0.1 ÷ 0.0144913

= 6.9

Pvalue ; Using the Pvalue from Zstatistic calculator :

Pvalue < 0.00001

Reject H0, if Pvalue < α

0.00001 < α ; We reject H0 ; Hence, there is significant evidence to support that more than 3% of the population of the city got infected by the virus.

Answer:

  Only Glass B is large enough

Step-by-step explanation:

For repetitive calculations, I like to use a calculator or spreadsheet. The attachment shows the volumes for the three glasses. Only Glass B has a volume that exceeds 75 cubic inches.

__

Note that Glass A has a diameter of 5 inches, so a radius of 2.5 inches.

Given:

The function is:

[tex]g(a)=\dfrac{8-a}{4}[/tex]

To find:

The difference quotient of the function.

Solution:

Formula for difference quotient of the function f(x) is:

[tex]DQ=\dfrac{f(x+h)-f(x)}{h}[/tex]

We have,

[tex]g(a)=\dfrac{8-a}{4}[/tex]

The difference quotient of the function g(a) is:

[tex]DQ=\dfrac{g(a+h)-g(a)}{h}[/tex]

[tex]DQ=\dfrac{\dfrac{8-(a+h)}{4}-\dfrac{8-a}{4}}{h}[/tex]

[tex]DQ=\dfrac{\dfrac{8-a-h-8+a}{4}}{h}[/tex]

[tex]DQ=\dfrac{-h}{4h}[/tex]

[tex]DQ=-\dfrac{1}{4}[/tex]

Therefore, the difference quotient of the given function is [tex]-\dfrac{1}{4}[/tex].

Answer:

  (b)  976 m³

Step-by-step explanation:

The total surface area is the sum of the areas of the faces and bases.

The two bases are triangles, each with area ...

  A = 1/2bh

So, the two of them together will have an area of ...

  A = 2(1/2)bh = bh

where b is the base of the triangle, and h is its height. These values are shown as 14 m and 24 m, respectively.

  Total base areas = (14 m)(24 m) = 336 m²

__

The total area of the rectangular faces is the sum of products of length and width. The width of each face is the same as the height of the prism, and the sum of face lengths is the perimeter of the triangular base.

The prism height is 10 m, and the perimeter of the base triangle is  (14 m +25 m +25 m) = 64 m. Then the lateral area of the prism is ...

  Total lateral area = (10 m)(64 m) = 640 m²

So, the total surface area of the prism is ...

  base area + lateral area = 336 m² + 640 m² = 976 m²

Answer:

The sum of the series is: 749

Step-by-step explanation:

Given

[tex]a_1 = 8[/tex]

[tex]a_{14} = 99[/tex]

[tex]n = 14[/tex]

Required

The sum of the series

This is calculated using:

[tex]S_n = \frac{n}{2}[a_1 + a_n][/tex]

Substitute 14 for n

[tex]S_{14} = \frac{14}{2}[a_1 + a_{14}][/tex]

[tex]S_{14} = 7[a_1 + a_{14}][/tex]

Substitute values for a1 and a14

[tex]S_{14} = 7[8 + 99][/tex]

[tex]S_{14} = 7*107[/tex]

[tex]S_{14} = 749[/tex]

Answer:

[tex]x =\sqrt 5[/tex]

[tex]y = \sqrt{5[/tex]

Step-by-step explanation:

Given

The attached triangle

Required

Solve for x

Considering angle 45 degrees, we have:

[tex]\cos(45) = \frac{y}{\sqrt{10}}[/tex] --- cosine formula i.e. adj/hyp

Solve for y

[tex]y = \sqrt{10} * \cos(45)[/tex]

In radical form, we have:

[tex]y = \sqrt{10} * \frac{1}{\sqrt 2}[/tex]

[tex]y = \sqrt{10/2}[/tex]

[tex]y = \sqrt{5[/tex]

To solve for x, we make use of Pythagoras theorem

[tex]x^2 + y^2 = (\sqrt{10})^2[/tex]

[tex]x^2 + y^2 =10[/tex]

Substitute for y

[tex]x^2 + (\sqrt 5)^2 =10[/tex]

[tex]x^2 + 5 =10[/tex]

Collect like terms

[tex]x^2 =10-5[/tex]

[tex]x^2= 5[/tex]

Solve for x

[tex]x =\sqrt 5[/tex]

as we are to find the perimetre of a circle 2πr

it will be 87.96m

since its a semi circle lets just divide by 2

now we get our answer that's 43.96m
