3x^2+23x^343x^2+13x-10

Answer:

166.9 miles per hour

Step-by-step explanation:

To round a number to the nearest tenth, look at the next place value to the right (the hundredths). If it's 4 or less, just remove all the digits to the right. If it's 5 or greater, add 1 to the digit in the tenths place, and then remove all the digits to the right. Then, the answer is 166.9.

Step-by-step explanation:

The base and height are perpendicular to each other. In each case, there is only one figure having a labeled h segment perpendicular to the labeled b.

The circumference of the base of the flowerpot is 84.8cm

Circumference of a circle can be described as the length or distance of a circle.

The formular that can be used to calculate the circumference of a circle is

= 2πr

Radius= diameter/2

= 27/2

= 13.5

The circumference can be calculated as follows

= 2πr

= 2 × 3.142 × 13.5

= 84.83

≅ 84.8 (to the nearest tenth)

Hence the circumference of the base of the flower pot is 84.8 cm

500 ml water 4 times a day = 500x4= 2000 ml water per day

there are 7 days in a week so,

2000 x 7 = 14000 ml

1000mililitre = 1 litre

14000ml = 14 L per week

Using the normal distribution, we have that:

a) 34.13% of pizzas were prepared and delivered between 20 and 25 minutes.

b) 34.46% of pizzas were prepared and delivered in less than 18 minutes.

c) 2.28% of the pizza will be free.

The z-score of a measure X of a normally distributed variable with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex] is given by:

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

The mean and the standard deviation are given, respectively, by:

[tex]\mu = 20, \sigma = 5[/tex]

For item a, the probability is the p-value of Z when X = 25 subtracted by the p-value of Z when X = 20, hence:

X = 25:

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

[tex]Z = \frac{25 - 20}{5}[/tex]

Z = 1

Z = 1 has a p-value of 0.8413.

X = 20:

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

[tex]Z = \frac{20 - 20}{5}[/tex]

Z = 0

Z = 0 has a p-value of 0.5.

0.8413 - 0.5 = 0.3413.

Hence 34.13% of pizzas were prepared and delivered between 20 and 25 minutes.

For item b, the probability is the p-value of Z when X = 18, hence:

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

[tex]Z = \frac{18 - 20}{5}[/tex]

Z = -0.4

Z = -0.4 has a p-value of 0.3446.

34.46% of pizzas were prepared and delivered in less than 18 minutes.

For item c, the proportion is one subtracted by the p-value of Z when X = 30, hence:

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

[tex]Z = \frac{30 - 20}{5}[/tex]

Z = 2

Z = 2 has a p-value of 0.9772.

1 - 0.9772 = 0.0228, hence 2.28% of the pizza will be free.

Answer:

X is a discrete Random variable where X is the number of races Jockey can win.

Step-by-step explanation:

To find - A jockey will ride horses in 10 different races at a race track today.

The number of races that the jockey will win is what type of random variable ?

Proof -

Given that,

A jockey will ride horses in 10 different races at a race track today.

Let us assume that,

X is the number of races Jockey can win

So,

X can take value 0, 1, 2, 3, ......10

As,

It can take countable finite values

So,

X is a discrete Random variable

∴ we get

X is a discrete Random variable where X is the number of races Jockey can win.

Answer:

G. 60 m²

Step-by-step explanation:

The lawn is in the shape of a trapezium.

The area of a trapezium can be found using the equation  0.5*h*(a+b), where h is the height and a and b are the top and bottom of the shape.

Area = 0.5*h*(a+b)

= 0.5*4*(12+18)

= 60 m²

Answer:

<1= 62

•it is 62 because it is an alternate interior angle which is congruent

<2= 83

• when you add the given angles 62 and 35 you get 97 and a triangle is 180 so you subtract 97 from 180

<3=35

• it is 35 because it is an alternate interior angle which is congruent

Step-by-step explanation:

62+35= 97

180-97= 83

Answer:

[tex]x=\sqrt{\dfrac{a(b-y^2)}{b}}[/tex]

Step-by-step explanation:

The given equation is :

[tex]x^2\div a+y^2\div b=1[/tex]

We need to find the value of x.

It can also written as :

[tex]\dfrac{x^2}{a}+\dfrac{y^2}{b}=1[/tex]

Subtract [tex]\dfrac{y^2}{b}[/tex] from both sides,

[tex]\dfrac{x^2}{a}+\dfrac{y^2}{b}-\dfrac{y^2}{b}=1-\dfrac{y^2}{b}\\\\\dfrac{x^2}{a}=\dfrac{b-y^2}{b}\\\\\text{Cross multiplying both sides}\\\\x^2=\dfrac{a(b-y^2)}{b}\\\\x=\sqrt{\dfrac{a(b-y^2)}{b}}[/tex]

Hence, the value of x is equal to [tex]\sqrt{\dfrac{a(b-y^2)}{b}}[/tex].
