Can somebody please tell me the answer to this

Answer:

b = -2 2/3

Step-by-step explanation:

Isolate the variable, b. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS.

First, subtract 5 from both sides:

-3b + 5 (-5) = 13 (-5)

-3b = 13 - 5

-3b = 8

Next, divide -3 from both sides:

(-3b)/-3 = (8)/-3

b = -8/3

b = -2 2/3

Answer:

Step-by-step explanation:

The initial value is always the value that corresponds to the independent variable being 0. Here, that's the first entry in the table. The initial Height is 0, when Time is 0.

__

The rate of change can be figured by looking at the change in Height for a change of 1 in Time. Here, the height changes by 200 m for every 1 min change in time. The rate of change is 200 m/min.

__

The equation can be written in slope intercept form using the rate of change and initial value:

  (dependent variable) = (rate of change)×(independent variable) + (initial value)

  H = 200T + 0

  H = 200T . . . . . . . . height in meters for time in minutes

Answer:

45

Step-by-step explanation:

let the longer tape be x

shorter tape be y

given

x+y=135⇒equation 1

also given

2y=x⇒equation 2

subtituting eq2 in eq1

2y+y=135

3y=135

y=135/3=45

hope this helps

Final answer:

The length of the shorter piece of tape is 45 centimetres after cutting a 135 centimetre tape into one piece that is twice as long as the other.

Explanation:

A length of tape is 135 centimetres long and it is cut into two pieces where the first piece is twice as long as the second piece. To solve this, let the length of the shorter piece be x centimetres. Therefore, the longer piece would be 2x centimetres long.

The total length of the tape is the sum of the lengths of both pieces, which gives us the equation:

x + 2x = 135

Combining like terms, we get:

3x = 135

Dividing both sides by 3, we find:

x = 135 / 3

x = 45

Therefore, the length of the shorter piece of tape is 45 centimetres.

Answer:

angle FBE

Step-by-step explanation:

By using the formula, the shortest angle is facing the shortest side

so the shortest angle is angle FBE

In triangle ADEF, angle E is the smallest angle.

In triangle ADEF, we are given that DE = 25 cm, EF = 17 cm, and DF = 20 cm. To determine which angle is the smallest, we need to compare the lengths of the sides opposite each angle. The smallest angle will have the smallest side opposite it. Let's compare the lengths:

Side DE is opposite angle D.

Side EF is opposite angle E.

Side DF is opposite angle F.

Since side EF (length 17 cm) is the smallest, angle E is the smallest angle in triangle ADEF.

Step-by-step explanation:

Para encontrar el
área total y el volumen del prisma triangular, primero calculamos el área de la base usando la fórmula para el área de un triángulo equilátero y luego calculamos el volumen y el área total usando esta área de base y la altura del prisma.

Para hallar el

área total
y el volumen de un prisma triangular con una altura de 6 cm y una base que es un triángulo equilátero de lado 5 cm, primero calculamos el área de la base. La fórmula para el área de un triángulo es A = (base
× height) / 2. En un triángulo equilátero, la altura se puede encontrar usando la fórmula height = (sqrt(3)/2)
× lado. Por lo tanto, la altura es height = (sqrt(3)/2)
× 5 cm.

Calculamos el área de la base (Abase) como Abase = (5 cm
× (sqrt(3)/2)
× 5 cm) / 2 = (5
× 5
× sqrt(3)) / 4, y luego redondeamos el resultado a dos cifras decimales para obtener el área de la base en centímetros cuadrados.

El volumen del prisma (V) es el producto del área de la base y la altura del prisma, por lo que V = Abase
× height. El área total del prisma es la suma del área de las tres caras rectangulares (Area laterales = perímetro de la base
× altura del prisma) más el doble del área de la base (Area total = Area laterales + 2
× Abase).

Para concluir, aplicamos los valores y calculamos tanto el
área total como el
volumen del prisma triangular, redondeando cada uno a dos cifras decimales.

Answer: 13.5 % would be the answer

To estimate the probability of a meerkat living between 12.3 and 14.2 years, we can use the empirical rule (68-95-99.7%).

The probability of a meerkat living between 12.3 and 14.2 years can be estimated using the empirical rule (68-95-99.7%).

Next, use a standard normal distribution table or a calculator to find the probabilities associated with these z-scores.

Finally, subtract the probability of the lower value from the probability of the higher value to find the probability of a meerkat living between 12.3 and 14.2 years.

Answer:

3825 pages

Step-by-step explanation:

Add the pages together:

1349+1281+1195 = 3825 pages

Danny read a total of 3,825 pages over winter break, which is well above 1,050 pages, indicating that it was very likely he had to read more than 1,050 pages.

Danny read three books over winter break. To determine the total number of pages Danny read, we need to add up the pages from each book. Here is the step-by-step explanation:

First book: 1,349 pages

Second book: 1,281 pages

Third book: 1,195 pages

Add these numbers together:

1,349 + 1,281 + 1,195 = 3,825 pages in total

Therefore, Danny read a total of 3,825 pages over the break. Clearly, this number is much greater than 1,050 pages, so without doing any calculations, we could confidently say that it's highly likely that Danny had to read more than 1,050 pages based on the individual page counts of each book provided.

The mean of the sampling distribution of p  is 0.70  and the standard deviation is 0.029 .

To find the mean and standard deviation of the sampling distribution of p , we can use the properties of sampling distributions.

Given:

Sample size, n = 250

Proportion of subscribed households who watch sports,  p = 0.70 (from the population)

Sample proportion of households who watch sports, [tex]\( \hat{p} = 0.75 \)[/tex](from the sample)

The mean of the sampling distribution of p  is equal to the population proportion, which is  p = 0.70 .

The standard deviation of the sampling distribution of p  can be calculated using the formula:

[tex]\[ \sigma_{\hat{p}} = \sqrt{\frac{p(1-p)}{n}} \][/tex]

Substituting the given values:

[tex]\[ \sigma_{\hat{p}} = \sqrt{\frac{0.70(1-0.70)}{250}} \]\[ \sigma_{\hat{p}} = \sqrt{\frac{0.70 \times 0.30}{250}} \]\[ \sigma_{\hat{p}} = \sqrt{\frac{0.21}{250}} \]\[ \sigma_{\hat{p}} = \sqrt{0.00084} \]\[ \sigma_{\hat{p}} = 0.029 \][/tex]

So, the mean of the sampling distribution of p  is 0.70  and the standard deviation is 0.029 .

Answer:

Y intercept is -10

Step-by-step explanation:

Answer:

slope = -4

y-intercept = -10

Step-by-step explanation:

Isolate the variable, y. Note the equal sign, what you do to one side, you do to the other. Subtract 4x from both sides:

4x (-4x) + y = -10 (-4x)

y = -4x - 10

Note the slope intercept form: y = mx + b

y = y

m = slope = -4

x = x

b = y-intercept = -10

slope = -4

y-intercept = -10

Given Information:

Distance = d = 12 miles

Time = t = 15 minutes

Required Information:

Speed of the bus = r = ?

Answer:

Speed of the bus = r = 48 mph

Step-by-step explanation:

We are given that a bus has traveled a distance of 12 miles in a time period of 15 minutes.

We are required to find the rate or speed at which the bus is traveling.

The relation is given by

[tex]rate = \frac{distance}{time}\\\\r = \frac{d}{t}[/tex]

Where r is the rate or speed, d is the distance and t is the time.

First let us convert time from minutes to hours

as we know 1 hour has 60 minutes,

15/60 = 0.25 hour

Now we will get the speed of the bus in miles per hour

[tex]r = \frac{d}{t}\\\\r = \frac{12}{0.25}\\\\r = 48 \: mph[/tex]

Therefore, the speed of the bus is 48 miles per hour.
