if a cup of diced cucumbers weighs 5.3 ounces, how many pounds of prepped cucumbers will you need for your 140 house salads?

Answers

46 pounds of prepped cucumbers are needed for 140 house salads.

It is given that one cup of diced cucumbers weighs 5.3 ounces.

Also, we know that one pound= 16 ounces or 1-ounce measure 1/16 pounds, we can do it in any way.

Thus, firstly, we will convert the ounces into pounds.

thus, 5.3 ounces= 5.3/16 pounds

Now, we need prepped cucumbers for 140 house salads, According to the given question.

thus, pounds needed for 140 house salads= 5.3/16*140

=>  46 pounds (nearly)

Thus, 140 house salads need nearly 46 pounds of cucumbers.

Answers

The value of c after solving the equation is 8.

For the polynomial to be divisible by x+2, hence x = -2

Given

p(x) = 4x³+cx²+x+2

p(-2) = 4(-2)³+c(-2)²+(-2)+2

p(-2) = 4(-8) + c(4)-2+2

p(-2) = -32+4c

If p(-2) = 0

0= -32+4c

-4c = -32

c = 32/4

c = 8

Hence we get the value of c as 8.

if you can notice the difference between 10- and 11-pound weights, which of the following weights could you differentiate from a 100-pound weight?

Answers

If we can notice the difference between 10- and 11-pound weight, we can  differentiate 110-pound weight from a 100-pound weight.

What is weight?

All things close to Earth are constantly subject to the force known as weight. All items are pulled downward toward the Earth's core by the gravity of the planet. On the other hand, weight is a measurement of how much gravity pulls an item downward. The mass of the thing has an impact on this force; the heavier the object, the stronger gravity's pull is. The force of gravity acting on a body is the most typical definition of weight given in introductory physics textbooks. This is sometimes formulated as W = mg, where W is the weight, m is the object's mass, and g is the acceleration due to gravity.

For the parallelogram to represent a rhombus, these following conditions need to be respected:

Parallelism of opposite sides.Congruence of opposite angles -> Same measures.All the sides are equal in length.The bisection of diagonals happen at right angles.

suppose you are testing to see if there is a difference in population mean lifetime of two brands (1,2) of batteries. random samples of batteries are taken for each brand and the following data are recorded: sample 1: n1

Answers

The test statistic of two brands of batteries is -2.177.

How to calculate test statistic?

[tex]n_1[/tex] = size of sample 1 = 16

[tex]n_2[/tex] = size of sample 2 = 21

[tex]\bar{x_1}[/tex] = mean of sample 1 = 210

[tex]\bar{x_2}[/tex] = mean of sample 2 = 225

[tex]\sigma_{1}[/tex] = standard deviation of sample 1 = 20

[tex]\sigma_{2}[/tex] = standard deviation of sample 2 = 23

T test is test for statistical hypothesis that follows t-distribution table under null hypothesis. T test is used when test statistic would follow a normal distribution if the value of a scaling term in the test statistic were known. So, for this case we use t test for test statistic,

t = [tex]\frac{\bar{x_1}-\bar{x_2}}{\sqrt{\frac{\sigma^2_1}{n_1}+\frac{\sigma^2_2}{n_2}}}[/tex]

t = [tex]\frac{210-225}{\sqrt{\frac{20^2}{16}+\frac{23^2}{21}}}[/tex]

t = [tex]\frac{-15}{\sqrt{\frac{400}{16}+\frac{529}{21}}}[/tex]

t = -15 / 7.0845

t = -2.117

Thus, the two brands of batteries have test statistic result is -2.117

Answers

Option-C is correct that is increase, wider. If the level of confidence rises when generating a confidence interval, the margin of error must increase and the confidence interval will get wider.

Given that,

By completing the blanks, the sentence is complete. When generating a confidence interval, the margin of error and the confidence interval will be larger if the level of confidence grows.

We have to find the accuracy of the confidence interval will increase with a larger sample size, so the margin of error and the confidence interval will be-----.

We know that,

If the level of confidence rises when generating a confidence interval, the margin of error must increase and the confidence interval will get wider.

The margin of error is a phrase that conveys how much sampling error there is in the data that was gathered or in the parameter estimates. Accordingly, the credibility of the poll will decrease as the margin of error increases. It displays the degree of estimation accuracy.

Three things determine the margin of error:

Confidence level: The margin of error grows in proportion to the level of confidence.

Sample size: The margin of error gets smaller as the size of the random sample gets bigger.

Step-by-step explanation:

to find the first 3 terms, substitute n = 1, 2, 3 into the nth term rule

n = 1 : 1² + 2(1) = 1 + 2 = 3

n = 2 : 2² + 2(2) = 4 + 4 = 8

n = 3 : 3² + 2(3) = 9 + 6 = 15

the first 3 terms are 3, 8, 15

Using some mathematical operations, we know that each player's headband and wristband are made from 16.18 inches of fabric and 8.63 inches of fabric.

What are mathematical operations?

A mathematical function known as an operation converts zero or more input values into a precisely defined output value.

The quantity of operands affects the operation's arity.

Parentheses, Exponents, Multiplication, Division, Addition, and Subtraction are collectively referred to as PEMDAS.

So, given that we've done it:

There are 35 players.

There are two coaches.

The cloth on the headbands measures 598.66 inches in length.

Just for the players, the wristbands include 302.05 inches of fabric.

Each player's headband's fabric length is specified by:

= Total inches/Total number of persons

= 598.66/37

= 16.18 inches

Each player's wristband's fabric length is specified by:

= Total inches/Number of persons

= 302.05/35

= 8.63 inches


Therefore, using some mathematical operations, we know that each player's headband and wristband are made from 16.18 inches of fabric and 8.63 inches of fabric.

Given that,

A keypad with 10 buttons marked 0 through 9 is located at the building's entrance.

We have to find how much probability is it that someone will correctly guess an 8-digit entry code.

We know that,

Probability is defined as the ratio of the number of required outcomes to the total number of outcomes.

One outcome is expected if the needed number of outcomes is 8-digits.

Since there are 10 numbers and 8 numbers need to be chosen, the total number of outcomes is ¹⁰C₈.

Considering that the lock can only be opened by 8 digits;

The probability that someone will properly guess a 8-digit input code is

P=1/¹⁰C₈

P=1/10!/8!2!

It will take about 16.7 years to reach $15500.

What is the interest rate?

The percentage that a lender adds to the amount of money lent to them is called an interest rate.

Given that, the initial deposited amount is P = $15000, the interest rate is r= 0.2% annually, and the final amount is $15500.

The interest earned is calculated by subtracting the initial amount from the final amount:

15500-15000

=500

Therefore, the interest earned is $500.

Now, the formula for the simple interest is:

interest = P × r × t

Substitute the known values:

500 = 15000 × 0.2% × t

500 = 15000 × 0.2/100 ×t

500 = 30t

t = 500/30

t = 16.7
