ANSWER

t = 10.27

EXPLANATION

Step 1: Given

Step 2: Divide both sides by 500

Step 3: Take the natural logarithm of both sides

Step 4: Divide both sides by 0.0675

Hence, t = 10.27 (rounded to the nearest hundredth).

The track lap time of the runner will be 3 3/5 minutes.

From the information, the runner has a track lap time of 1 minute while at a run, 4 minutes while at a jog, and 7 minutes while at a walk. If 2/5 of the lap is paced at a run, 1/3 at a jog, and 4/15 at a walk.

The track lap time of the runner will be:

= (2/5 × 1 minute) + (1/3 × 4 minutes) + (4/15 × 7 minutes)

Note that 1 minute = 60 seconds

(2/5 × 1 minute) + (1/3 × 4 minutes) + (4/15 × 7 minutes)

= 24 seconds + 80 seconds + 112 seconds

= 216 seconds

= 3 minutes 36 seconds.

Answer:

omg what is standard deviation that was on my psat today

Answer:

i cannot see the lines very well, but i can tell you how to find slope

Step-by-step explanation:

slope is rise/run. find where the line hits a intersection on the graph, and count the squares across the graph where it hits another intersection. it should not be on the line though, because that is only the run. then count how many squares up it takes till you touch where the line hits another intersection. that is the rise. then divide the rise by the run.

The price of the house will double the original value in 35 years

The given parameters from the question are

Initial value of the house = $265,100

Rate of gain = 2% of its value every year

An exponential function is represented as

y = a *(1 + r)^x

Where

This means that

a = 265,100

r = 2%

So, we have

y = 265,100 *(1 +2%)^t

When the price doubles, we have

2 * 265,100 = 265,100 *(1 +2%)^t

Divide both sides by 265,100

So, we have

2  = (1 +2%)^t

Evaluate the sum

So, we have

2 = 1.02^t

Take the logarithm of both sides

t * log(1.02) = log(2)

Divide

t = log(2)/log(1.02)

Evaluate

t = 35

Hence, the number of years is 35

The area under the standard normal curve between z=0 and z=3 is 0.4987.

It should be noted that because the normal distribution is symmetrical on both sides of the mean and is a continuous probability distribution, the right side of the center is the opposite of the left side.

The normal distribution was first termed by early statisticians who observed that the same shape repeatedly appeared in many distributions. The characteristics of normal distributions are as follows: Bell-like in its symmetry. The distribution's mean and median, which are both at its center, are equal.

The area will be illustrated as:

P(0 < Z < 3)

From the distribution table. In this case, it's important to look at the normal distribution table under the z score for the values of zero less than Z and Z less than 3. This will be:

The number of gorillas at the safari park is 4.

Let the number of gorillas at the safari park be x.

It is given that there are 24 more buffalo than there are gorillas.

Number of buffalo at the safari park = 24 + x

There are 7 times as many wallabies as there are gorillas.

Number of wallabies at the safari park = 7x

Now, the number of buffalo is the same as the number of wallabies.

So, we equate their numbers to find the value of x i.e. number of gorillas.

24 + x = 7x

7x - x = 24

6x = 24

x = 4

Therefore, the number of gorillas at the safari park is 4.

The true statements about the solutions to this number line include the following:

A. -1 is a solution.

E. -1.5 is a solution.

F. All negative numbers are solutions.

A number line can be defined as a type of graph with a graduated straight line which contains both positive and negative numbers (numerical values) that are placed at equal intervals along its length.

This ultimately implies that, a number line can be used to determine the difference between two numbers such as 23 and 12. Also, a number line typically increases in numerical value towards the right and decreases in numerical value towards the left.

In conclusion, we can reasonably infer and logically deduce that an inequality which represent the solutions to this number line in interval notation is given by: -1 ≤ x ≤ ∞.

Answer:

(a) There are 22 workers are available in the factory.

Step-by-step explanation:

(a) Let the number of workers in the factory be x.

Basic rate = $15

Working hours in a week  = 48 hours

Total wages in a week = $ 15840

If no overtime is to be paid then according to question,

Amount paid to 1 worker = 48 X 15 = $ 720

Amount paid to x worker = 720x

15840 = 720

x = 15840/720

x = 22

The interest that they will they have to pay if it takes them 4 years and 3 months to repay the loan is $1377.

From the information, Isaac's parents borrow $3600.00 from the bank for new appliances for their kitchen and the simple interest rate is 9% per year.

Principal = $3600

Rate = 9%

Time = 4 years 3 months = 4.25

It should be noted that simple interest is calculated as:

= Principal × Rate × Time / 100

= (3600 × 9 × 4.25) / 100

= 137700 / 100

= $1377

z = 6

Step-by-step explanation:

The angle in the middle is a right angle with a measure of 90°

Together, all three angles, makes a stright angle which is measured 180°.

So we can write the following equation to find the value of z:

5z + 1 + 59 = 90 (we don'thave to include the middle angle since we already its measure)

add like terms

5z + 60 = 90 subtract 60 from both sides

5z = 30 divide both sides by 5

z = 6
