Answer:

h ≤ 45

Step-by-step explanation:

The maximum height is 45 feets

Let the height of the object = h

Hence, the sentence means that the height, h of the object cannot be beyond 45 feets ;

This means the height can be any number of feets less than or equal to 45 feets

Hence, h ≤ 45

Answer:

9 yrs ago

Step-by-step explanation:

(50-x)(20-x) = 451

x^2-70x + 1000 = 451

x^2-70x + 549 = 0

(x-9)(x-61) = 0

x = 9 (if it was 61 yrs ago, the father and son both wouldnt be a live)

Step-by-step explanation:

A right triangle is defined as a triangle with sides in the ratio 3:4:5. Pythagorean Doubles are triangles whose sides have had a ratio of the whole numbers as their sides. Even if the sides are multiplied by any number, the result is still a right triangle with sides in the ratio 3:4:5. For instance, 6, 8, and 10 are all numbers.

Answer:

Step-by-step explanation:

#27). 6k² = 48

k = √8 = 2√2

x = [tex]\frac{8}{2\sqrt{2} }[/tex] = 2√2 cm

y = [tex]\frac{12}{2\sqrt{2} }[/tex] = 3√2 cm

#29). 16k² = 48

k = √3

x = [tex]\frac{8}{\sqrt{3} }[/tex] = [tex]\frac{8\sqrt{3} }{3}[/tex] cm

y = [tex]\frac{12}{\sqrt{3} }[/tex] = 4√3 cm

Answer:

skewed to the right

Step-by-step explanation:

Given that

the mean household income for the last year was $46,200

And, the median was $37,800

In the case when the historgram is prepared so the income would be skewed to the right as the mean i..e $46,200 is more tha the median i.e. $37,800

So, the distribution would be right skewed

Hence, the same would be considered and relevant

Answer:

Height = 4 cm and slant height = 5 cm

Step-by-step explanation:

Given that,

The surface area of the cone, A = 75.4 cm²

Radius, r = 3 cm

The surface area of the cone is given by the formula as follows :

[tex]A=\pi r^2+\pi rl[/tex]

Put all the values,

[tex]75.4=3.14\times 3^2+3.14\times 3\times l\\\\75.4=28.26+9.42l\\\\75.4-28.26=9.42l\\\\47.14=9.42l\\\\l=\dfrac{47.14}{9.42}\\\\l=5\ cm[/tex]

Also,

[tex]l^2=r^2+h^2\\\\h=\sqrt{l^2-r^2}\\\\h=\sqrt{5^2-3^2}\\\\h=4\ cm[/tex]

Hence, the height of the cone is 4 cm and the slant height is 5 cm.

Answer:

a) 5 pizzas need to be ordered and half of a pizza will be left over aka 0.5

b) $45

Step-by-step explanation:

Answer:

In the explanation I'm 80% sure it's this

Step-by-step explanation:

4 quarters in the pizza so

18 divided by 4= 4.5

4.5 rounded is 5 so she will need 5 pizzas because you can't buy 4 1/2 pizzas.

10*5= 50 so she will need to spend 50$ on the pizza.

Answer:

Step-by-step explanation:

1). Since, line segment AB passes through two points ((0, 0) and (3, 4)

Therefore, slope of the segment = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]

                                                        = [tex]\frac{4-0}{3-0}[/tex]

                                                        = [tex]\frac{4}{3}[/tex]

2). Relative minimum of the graph from B to C → (5, 0)

   Therefore, x-coordinate of the relative minimum → x = 5

3). From the graph attached,

   f(3) = 4

   f(4) = 1

   f(6) = 1

   f(7) = 4

   Therefore, f(3) + f(4) + f(6) + f(7) = 4 + 1 + 1 + 4

                                                          = 10

Answer:

0.0082 = 0.82% probability that the mean battery life would be greater than 523.8 minutes

Step-by-step explanation:

To solve this question, we need to understand the normal probability distribution and the central limit theorem.

Normal Probability Distribution:

Problems of normal distributions can be solved using the z-score formula.

In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the p-value, we get the probability that the value of the measure is greater than X.

Central Limit Theorem

The Central Limit Theorem estabilishes that, for a normally distributed random variable X, with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]s = \frac{\sigma}{\sqrt{n}}[/tex].

For a skewed variable, the Central Limit Theorem can also be applied, as long as n is at least 30.

Standard deviation of 86 minutes with a mean life of 505 minutes.

This means that [tex]\sigma = 86, \mu = 505[/tex]

Sample of 120:

This means that [tex]n = 120, s = \frac{86}{\sqrt{120}}[/tex]

What is the probability that the mean battery life would be greater than 523.8 minutes?

This is 1 subtracted by the p-value of Z when X = 523.8. So

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

By the Central Limit Theorem

[tex]Z = \frac{X - \mu}{s}[/tex]

[tex]Z = \frac{523.8 - 505}{\frac{86}{\sqrt{120}}}[/tex]

[tex]Z = 2.39[/tex]

[tex]Z = 2.39[/tex] has a p-value of 0.9918.

1 - 0.9918 = 0.0082

0.0082 = 0.82% probability that the mean battery life would be greater than 523.8 minutes

Answer:

50.24 ft

Step-by-step explanation:

diameter = 250  -----  radius = 125  (radius of the smaller circle)

125+4 = 129  ( radius of the bigger circle)

129-125 = 4

4² x pi   =  16x 3.14  = 50.24

Answer:

Step-by-step explanation:

The area (A) of a trapezoid is calculated as follows:

A = 1/2 * sum of the parallel sides * height

In this case:

A = 1/2 * (3.4 + 1.1) * 2 = 4.5 cm^2.

[tex]\lim_{x \to -3} \sqrt{x^2 - 8}[/tex]

Here we have

[tex]\lim_{x \to -3} f(x)=f(x)[/tex]

Therefore

[tex]\lim_{x \to -3} \sqrt{x^2 - 8} = \lim_{x \to -3} \sqrt{(-3)^2 - 8} = \lim_{x \to -3} \sqrt{9 - 8} = \lim_{x \to -3} \sqrt{1}[/tex]

[tex]\lim_{x \to -3} \sqrt{1}= \lim_{x \to -3} 1 = 1[/tex]
