Answer:

y=2x+0

Step-by-step explanation:

The slope is rise over run (which is 10/5, so 2) and the y-intercept is 0,0

Answer: Yes that I correct.

Step-by-step explanation:

Because 25 times 4 is 100 and what you do to the bottom you have to do to the top so 7 times 4 is 28

Answer:

We fail to reject the Null and conclude that the standard deviation of the contributions of all sanitation workers is not greater than that of all workers living in the city.

Step-by-step explanation:

σ = 1.40 ; σ² = 1.40² = 1.96

H0 : σ² = 1.96

H0 : σ² > 1.96

Given that:

Sample size, n = 12

Population Standard deviation, σ = 1.40

Sample standard deviation, s = 1.75

α = 0.01

The test statistic :

χ² = [(n-1)s²] ÷ σ²

χ² = [(12 - 1) * 1.75²] ÷ 1.40²

χ² = (11 * 3.0625) ÷ 1.96

χ² = 33.6875 / 1.96

χ² = 17.1875

χ² = 17.19

Using the Pvalue from Chisquare score calculator;

df = n - 1 ; 12 - 1 = 11

Pvalue ; χ²(17.19, 11) = 0.10238

Since Pvalue > α ; We fail to reject the Null and conclude that the standard deviation of the contributions of all sanitation workers is not greater than that of all workers living in the city.

Answer:

y=-1/8x

Step-by-step explanation:

Its non of the above. Though I did have a question like that, if there is a choice below the square, that has the following properties, that must be the answer:

7 sides

1 right angel

______________________________________________________

But if you are talking about it being 1 of the 2, its non of the 2 that is in the picture. The option below square must be the answer if I am right according to what I had.

Hope it helps ! The things that I told you about the figure is the only way I can tell you. Sorry, but have a great day and good luck.

26.3

Step-by-step explanation:

Delta Math

The radius of a hemisphere with a volume of [tex]38153[/tex] in", to the nearest tenth of an inch is [tex]26.3[/tex].

A circle's or sphere's radius is any line segment that connects the object's centre to its perimeter in classical geometry; in more contemporary usage, it is also the length of those line segments.

The word "radius" is derived from the Latin word "radius," which also refers to the spoke of a chariot wheel. Use the equation  [tex]r =\frac{D}{2}[/tex]  to determine the radius, which is equal to half the diameter. This is the same process used to determine a circle's radius from its diameter.

A hemisphere's volume is equal to  [tex]\frac{2}{3} \pi r^3[/tex]  cubic units. Where is an estimated constant with a value of [tex]3.14[/tex]. The hemisphere's radius is denoted by "r."

Required calculations are:

V = r

r = radius.

Given, V = 38153 in³

[tex]38153 = \frac{2}{3} \pi r^3[/tex]

[tex]r^3 = \frac{3 \times 38153}{2 \times \pi }[/tex]

[tex]r = 3\sqrt{\frac{3 \times 38153}{2 \times \pi }}[/tex]

r =26.3 in

Therefore, the radius of a hemisphere with a volume of [tex]38153[/tex] in", to the nearest tenth of an inch is [tex]26.3[/tex].

Answer:

136

Step-by-step explanation:

First you need to know that there are 2 triangles in the image.

One triangle (the smaller one) has sides that measure 119 (the side) and 56 (the bottom).

The other triangle (the bigger one) has sides that measure 119 + ? (the side) and 120 (the bottom).

Let's replace the 119 + ? with an x so that the entire side length of the big triangle measures x.

1. Make a proportion using ratios. For the ratios of each triangle, we can do side over bottom lengths and then set them equal to each other.

119  =    x              sides

56        120            bottoms

2. You can cross multiply, or just solve for x.

119*120= 14280

14280/56= 255

3. Then subtract the total length minus 119 to find the question mark

255 - 119 = 136

Answer:

+6/27=?/?

Step-by-step explanation:

+6/27=?/? will be the next number as the patter keeps increasing the numerator by 1 and denominator by 9

Step-by-step explanation:

w(idth) = 2.5 inches for both boxes

h(eight) = 10 inches for both boxes

l(ength)l(arge) = 8 inches

l(ength)s(mall) = 75% of ll (=> of 8 inches)

=> ls = 8 × 75/100 = 2 × 75/25 = 2 × 3 = 6 inches

vl (volume large) = 8 × 2.5 × 10 = 200 inches³

vs (volume small) = 6 × 2.5 × 10 = 150 inches³

the difference of these two volumes is 50 inches³

the units to be used is cubic inches (inches³). we are talking about volumes. not lengths (inches), not areas (inches²).

the reason - for a volume we need to multiply 3 lengths (measured in simple inches). so, inch multiplied by inch is inch². this multiplied by inch again is then inch³.

Step-by-step explanation:

Molly is paid £280 for 35 hours' work, so

  £280/(35 h) = £8/h

In the next 5 hours, her pay jumps to £350, so she earns at a rate of ...

  (£350 -280)/(5 h) = £70/(5 h) = £14/h

The difference in her pay rates is £14/h -£8/h = £6 per hour.
