Answer:

8 people

Step-by-step explanation:

4/8 simplifies to 1/2. If there’s 4 fruitcakes, divide each one by 1/2 to get 2. Now you have 8 pieces of fruitcake for 8 people! It’s helpful if you draw it out too

Answer:

Option 1.) y = 125°

Step-by-step explanation:

We know that sum of exterior angles of any polygon is 360°. Therefore we can say;

70° + 60° + 65° + 40° + y° = 360°

235° + y° = 360°

y = 360 - 235

y = 125°

Therefore the measure of ∠y = 125°

Using the normal distribution, it is found that:

A. There is a 0.0228 = 2.28% probability that a randomly selected score is greater than 81 points.

B. 81.85% of students scores are between 69 and 78.

C. The student scored in the 99.87th percentile.

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]

In this problem, the mean and the standard deviation are given, respectively, as:

[tex]\mu = 75, \sigma = 3[/tex].

Item a:

The probability is one subtracted by the p-value of Z when X = 81, hence:

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

[tex]Z = \frac{81 - 75}{3}[/tex]

Z = 2.

Z = 2 has a p-value of 0.9772.

1 - 0.9772 = 0.0228.

0.0228 = 2.28% probability that a randomly selected score is greater than 81 points.

Item b:

The proportion is the p-value of Z when X = 78 subtracted by the p-value of Z when X = 69, hence:

X = 78:

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

[tex]Z = \frac{78 - 75}{3}[/tex]

Z = 1.

Z = 1 has a p-value of 0.8413.

X = 69:

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

[tex]Z = \frac{69 - 75}{3}[/tex]

Z = -2.

Z = -2 has a p-value of 0.0228.

0.8413 - 0.0228 = 0.8185.

81.85% of students scores are between 69 and 78.

Item c:

The percentile is the p-value of Z when X = 84, multiplied by 100, hence:

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

[tex]Z = \frac{84- 75}{3}[/tex]

Z = 3.

Z = 3 has a p-value of 0.9987.

The student scored in the 99.87th percentile.

Answer: 0.1334

Step-by-step explanation:

Given

There are seven trails with a probability of success is  [tex]p=\frac{1}{4}[/tex]

[tex]\therefore q=1-p\\q=1-\frac{1}{4}\\q=\frac{3}{4}[/tex]

Using the binomial distribution, the Probability of exactly no success i.e. x=0 is given by

[tex]\Rightarrow ^7C_0\cdot p^0 \cdot q^{7-0}\\\Rightarrow 1\times(\frac{1}{4})^0 \cdot (\frac{3}{4})^7\\\Rightarrow 1\times 1 \cdot (0.75)^7\\\Rightarrow 0.1334[/tex]

Answer:

Obtuse

Step-by-step explanation:

Right = has angle measure of 90°

Acute = has angle measure less than 90°

Equilateral = 2 or more angles whose angle measures are congruent to others

Circle = measures 360°

Obtuse = Angle measure greater than 90° and less than 180°

Respuesta:

960 m

Explicación paso a paso:

Paso 1: Información provista

Superficie del parque (S): 1600 m²

Paso 2: Calcular cuanto mide cada lado (l) del parque

El parque es un cuadrado, por lo que podemos encontrar la longitud del lado usando la siguiente fórmula.

S = l²

l = √S = √1600 m² = 40 m

Paso 3: Calcular el perímetro del parque (P)

El perímetro es la cantidad de metros que reccorre cuando da una vuelta completa.

P = 4 l = 4 × 40 m = 160 m

Paso 4: Calcular la distancia recorrida cuando corre 6 vueltas

Debemos multiplicar el perímetro por 6.

6 × 160 m = 960 m

Answer:

C

Step-by-step explanation:

on C 1 ice cream cost $1.2 if you multiply 1.2x12=14.4

THE CORRECT ANSWER IS...

C ($9.59 for 8 scoops)

Step-by-step explanation:

well, if you divided 14.89 by 12 it equals $1.24. so that means it's $1.24 for one single scoop for that one. then for B if you divided $7.99 by 5, you'd get $1.60, so that's $1.60 per scoop for B. lastly $9.59 divided by 8 is $1.20, which is the lowest price per scoop, so that makes it the best and most affordable one. i hope i explained that easily, but basically all in all, the answer is C.

The correct answer is in BOLD.

1.24 (A)

1.60 (B)

Answer:

11 sq. units

Step-by-step explanation:

Find the area of the rectangle first, then find the area of the three white triangles.

Area of the rectangle

= 6×5

= 30 sq. units

Total area of the three white triangles

= (4×5)÷2 + (2×3)÷2 + (6×2)÷2

= 19 sq. units

The area of the rectangle minus the total area of white triangles:

Area of the green triangle

= 30-19

= 11 sq. units

Answer:

y=-x+3

Step-by-step explanation:

To find slope, you would want to use the formula for slope which is y=mx+b.

we are basically isolating the "y". So to find slope we would just subtract the "x" from both sides, leaving use with a negative "x" plus 3 on one side and a y on the other.

Answer:

0.982

Step-by-step explanation:

Use your calculator to find the trigonometric ratio sin 79°

Answer: 0.982

Answer:

A general rule for functions of the general form:

y = A*x^n

is:

dy/dx =  n*A*x^(n - 1)

Then, for the function:

y^2 = 4*a*x

Then we can rewrite this as:

y = (4*a*x)^(1/2) = √(4*a)*x^(1/2)

Then we have:

A = √(4*a)

n = 1/2

Now we can use the above rule to get

dy/dx = (1/2)*√(4*a)*x^(1/2 - 1)

dy/dx = (1/2)*√(4*a)*x^(-1/2)

dy/dx = (1/2)*√(4*a/x)

dy/dx = √(1/4)*√(4*a/x)

dy/dx = √( (1/4)*4*a/x)

dy/dx = √(a/x)
