Answer: $7

Step-by-step explanation: So $27 -$6= $21.Then you Divide by 3 and you will get $7 for each beaker.

Answer:

$7

Step-by-step explanation:

In order to find the total cost of the 3 beakers, take away $6 from the total amount Adam has.

$27 - $6 = $21

$21 is the amount needed for 3 beakers, hence to find 1 beaker, you just have to divide $21 by 3.

$21 ÷ 3 = $7

Therefore, each beaker costs $7.

Aislinn bought a new car. After 8 months, the odometer read 14,010 miles. How many miles did
UNO [17]

d) Aislinn's average per month on her car is 1,751 miles per month.

<h3>How to find the average speed?</h3>

The average speed is calculated by dividing the total distance traveled by the total time it took to travel that distance. Speed is the rate at which something moves at any given time.

Average speed is the average rate of speed over the course of a journey. Velocity exists as the directional speed of a moving object as an indication of its rate of change in position as observed from a specific frame of reference and measured by a specific time standard.

Given,

After 8 months, the odometer read 14,010 miles.

Solution:

t = 8,

d =  14,010 miles,

s = ?

s = d/t

s =  14,010/8

s = 1751 miles/month.

Aislinn drove an average of 1,751 miles per month.

Determine if the sequence below is arithmetic or geometric and determine the common difference/ratio in simplest form.
Nana76 [90]

Step-by-step explanation:

this is clearly not a linear sequence (the terms don't have the same difference).

so, it has to be a geometric sequence.

the common ratio is r.

s2 = s1 × r

16 = 64 × r

r = 16/64 = 1/4

control :

s3 = s2×r

4 = 16 × 1/4 = 4

correct.

In-s [12.5K]

Answer:

Step-by-step explanation:

h = √6 units

b = √9 units

A = b*h/2 = √6·√9 /2 = √(6·9)/2 = √(2·3·3·3)/2 = 3√3 /2 units ²≈ 2.6 units²

Test scores are normally distributed with a mean of 500. Convert the given score to a z-score, using the given standard deviatio
Bond [772]

Answer:

The percentage of students who scored below 620 is 93.32%.

Step-by-step explanation:

Problems of normally distributed samples are solved using the z-score formula.

In a set with mean \mu and standard deviation \sigma, the zscore of a measure X is given by:

Z = \frac{X - \mu}{\sigma}

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 pvalue, we get the probability that the value of the measure is greater than X.

In this question, we have that:

\mu = 500, \sigma = 80

Percentage of students who scored below 620:

This is the pvalue of Z when X = 620. So

Z = \frac{X - \mu}{\sigma}

Z = \frac{620 - 500}{80}

Z = 1.5

Z = 1.5 has a pvalue of 0.9332

The percentage of students who scored below 620 is 93.32%.
