Answer: 3:4

Step-by-step explanation: because the ratio of a :b is 2:3 which means b is 3 . And the ratio of a:c is 3 :4 which means c is 4.

And 3:4 is in simplest form .

Hope it helps.

Answer:

The required ratio is b:c = 9:8

Step-by-step explanation:

We are given:

The ratio a:b = 2:3

and the ratio a:c = 3:4

We need to find the ratio b:c

We are given a:b=2:3

We can write it as: [tex]\frac{a}{b}=\frac{2}{3}[/tex]

Finding value of a: [tex]\frac{a}{b}=\frac{2}{3}\\3a=2b\\a=\frac{2b}{3}[/tex]

Now, we have a:c = 3:4

We can write it as: [tex]\frac{a}{c}=\frac{3}{4}[/tex]

Putting value of a and finding b:c

[tex]\frac{a}{c}=\frac{3}{4}\\Put\:a=\frac{2b}{3}\\\frac{2b}{3}}\times \frac{1}{c}=\frac{3}{4} \\Finding\:value\:of\:b/c\\\frac{b}{c}=\frac{3\times 3}{4 \times 2}\\ \frac{b}{c}=\frac{9}{8}[/tex]

So, we get b/c = 9/8

We can write them in ratio as: b:c = 9:8

Answer:

[tex]d' = (9,3)[/tex]

Step-by-step explanation:

Given

[tex]c = (5,-7)[/tex]

[tex]d = (-3,9)[/tex]

Transformation: 270 degrees rotation

Required

Determine the coordinates of d

I'll treat the question as: Determine the coordinates of d after the transformation

When a coordinate point d(x,y) is rotated 270 degrees about the origin, the new image of the point is:  d'(y,-x)

In this case: [tex]d = (-3,9)[/tex]

[tex]x = -3[/tex]

[tex]y = 9[/tex]

So, the image of d is:

[tex]d' = (y,-x)[/tex]

[tex]d' = (9,-(-3))[/tex]

[tex]d' = (9,3)[/tex]

Step-by-step explanation:

rectangle area = 144 cm

Formula: A= L*H

The give the length which is 16

144 = 16*H

Since they gave u the area instead of the height, work backwards

144/16 = 16/16 *H

9 = H

Now you have the length and height

Length: 16

Height: 9

Perimeter is when you add up all the sides

The top and bottom of the rectangle is the length which is 16 so

16 + 16 = 32

The left and right side of the rectangle is the height which is 9 so

9 + 9 = 18

Now add then both

32 + 18 = 50

So the perimeter of the rectangle is 50

Answer: Number of cheese pizzas = 6

Number of sausage pizzas =18

Number of pepperoni pizzas = 12

Number of supreme pizzas =  3

Step-by-step explanation:

Let x= Number of cheese pizzas.

Number of sausage pizzas = 3x

Number of pepperoni pizzas = 2x

Number of supreme pizzas = [tex]\dfrac{2x}{4}=\dfrac{x}{2}[/tex]

Total pizzas = [tex]x+3x+2x+\dfrac{x}{2}=39[/tex]

[tex]\Rightarrow\ \dfrac{13x}{2}=39\\\\\Rightarrow\ x=\dfrac{39}{13}\times2\\\\\Rightarrow\ x=6[/tex]

Number of cheese pizzas = 6

Number of sausage pizzas = 3(6) = 18

Number of pepperoni pizzas = 2(6) = 12

Number of supreme pizzas =  [tex]\dfrac{12}{4}=3[/tex]

Answer:

The probability is 0.017429

Step-by-step explanation:

We start by calculating the z-score

Mathematically;

z-score = (x-mean)/SD/√n

In this case;

x = 273

mean = 276

SD = √(variance) = √81 = 9

n = 40

Substituting these values into the z-score formula, we have that;

z = (273-276)/9/√40

z = -2.11

So we proceed to get the probability

the probability in this case is;

P( z < -2.11)

We can use the normal distribution table for this

Our answer will be

P( z < -2.11) = 0.017429

Answer:

The formula for the gray squirrel population is [tex]n = 3125\cdot 2^{\frac{t}{6} }[/tex].

Step-by-step explanation:

The statement indicates that gray squirrel population increases geometrically, population is doubled every 6 years. That is:

[tex]\frac{n_{t+6}}{n_{t}} = 2[/tex] (1)

If the population after 30 years is 100000, then we construct the following relationship:

[tex]\frac{n_{6}}{n_{o}} \cdot \frac{n_{12}}{n_{6}}\cdot \frac{n_{18}}{n_{12}}\cdot \frac{n_{24}}{n_{18}}\cdot \frac{n_{30}}{n_{24}} = 2^{5}[/tex]

[tex]n_{30} = 2^{5}\cdot n_{o}[/tex]

[tex]n_{o} = \frac{n_{30}}{2^{5}}[/tex] (2)

[tex]n_{o} = \frac{100000}{2^{5}}[/tex]

[tex]n_{o} = 3125[/tex]

A geometric progression for the grey squirrel population is defined by the following formula:

[tex]n = 3125\cdot 2^{\frac{t}{6} }[/tex] (3)

Where:

[tex]t[/tex] - Time, measured in years.

[tex]n[/tex] - Population of gray squirrels.

80% confidence interval with Maximum error is

(3.61, 3.79)

Step-by-step explanation:

Explanation

Given the mean of the sample ( x⁻) = 3.7

The maximum error  = 0.09

80% confidence interval is determined by

[tex](x^{-} - Z_{0.80} \frac{S.D}{\sqrt{n} } , x^{-} +Z_{0.80} \frac{S.D}{\sqrt{n} })[/tex]

( x⁻ - M.E , x⁻ + M.E)

( 3.7 - 0.09 , 3.7 +0.09)

(3.61 , 3.79)

Final answer:-

80% confidence interval with Maximum error is

(3.61, 3.79)

There were 77% of the entries with a score less than 68. Therefore, the correct answer is option A.

Given that, at a recent contest with 1,000 entries, a score of 68 was at the 77th percentile of the distribution of all the scores.

A score X being in the xth percent of a distribution means that x% of the scores are below X and 100 – x% of the scores are above X.

In this question, we have that:

A score of 68 is in the 77th percentile of the distribution.

This means that 77% of the scores are below 68, and 100 – 77 = 23% of the scores are above 68.

Therefore, the correct answer is option A.

Answer:

Step-by-step explanation:

Surface Area of a Cuboid

Given a cuboid of dimensions x,y, and z, the surface area is:

A = 2xy + 2yz + 2xz

The first cuboid of dimensions 1,a,9 has a surface area of:

A1 = 2a + 18a + 18 = 20a + 18

The first cuboid of dimensions 2,a,7 has a surface area of:

A2 = 4a + 14a + 28 = 18a + 28

Both areas are equal, thus:

20a + 18 = 18a + 28

Rearranging:

20a - 18a = 28 - 18

2a = 10

a = 5
