Answer:

65   3    46

Step-by-step explanation:

Answer:

a² + 1 = 65

18/2a = 3

6(d + 8) - 10d = 46

Step-by-step explanation:

a² + 1 when a = 8

first, plug in 8 for a.

begin simplifying by finding 8², which is just 8 · 8.

finish simplifying by adding 64 + 1.

therefore, when a = 8, a² + 1 = 65.

18/2a when a = 3

first, plug in 3 for a.

begin simplifying by multiplying 2 · 3.

finish simplifying by dividing 18 ÷ 6.

therefore, when a = 3, 18/2a = 3.

6(d + 8) - 10d when d = 1/2

(i'm going to convert 1/2 to 0.5 because i prefer working with decimals rather than fractions)

so... 6(d + 8) - 10d when d = 0.5

first, plug in 0.5 for d.

begin simplifying by distributing 6 to 0.5 and 8, which is just 6 · 0.5 and 6 · 8.

after distributing, your expression is 3 + 48 - 10(0.5).

continue simplifying by multiplying -10 · 0.5.

add 3 + 48.

finally, finish simplifying by subtracting 5 from 51.

therefore when d = 1/2 or 0.5, 6(d + 8) - 10d = 46.

i hope this helps! have an amazing day <3

Can someone please help me on these four problems. The photo is linked above

A rapid strep test is often given in a clinical setting so that, if needed, antibiotics can begin as soon as possible. Researchers at Cochrane.org evaluated the effectiveness of rapid strep tests and found that one type had a sensitivity (ability to correctly detect people with strep) of 85.4% and a specificity (ability to correctly identify people who do NOT have strep) of 95%
Fill in the following chart, assuming that you have a group of 10,000 people, 15% of whom actually have strep throat.
Patient is given a rapid strep test
Result is positive Result is negative totals
Has strep throat
Does not have strep
Totals 10,000
For a population of patients similar to those described in the stem of this problem, use the chart find each of the following probabilities. Write you answer as an abbreviated probability statement with your answer to four decimal places without using a percent symbol. For example, P(strep) = 0.15
A) The probability that a randomly chosen patient has strep throat and tests positive
B) The probability that a randomly chosen patient tests positive for strep throat.
C) The probability that a randomly chosen person actually has strep throat, given that they have tested positive.

A trial balance has total debits of $36,000 and total credits of $48,500. Which one of the following errors would create this imbalance?

A.) A $6,250 debit to utilities expense in a journal entry was incorrectly posted to the ledger as a $6,250 credit, leaving the utilities expense account with a $7,000 debit balance.

B.) A $12,500 debit to salaries expense in a journal entry was incorrectly posted to the ledger as a $12,500 credit, leaving the salaries expense account with a $2,350 debit balance.

C.) A $6,250 credit to consulting fees earned (revenues) in a journal entry was incorrectly posted to the ledger as a $6,250 debit, leaving the consulting fees earned account with a $14,300 credit balance.

D.) A $6,250 debit posting to accounts receivable was posted mistakenly to land.

E.) A $12,500 debit posting to equipment was posted mistakenly to cash.

F.) An entry debiting cash and crediting accounts payable for $12,500 was mistakenly not posted.

Scientists are conducting an experiment with a gas in a sealed container. The mass of the gas is measured, and the scientists realize that the gas is leaking over time in a linear way. Its mass is leaking by 9.7 grams per minute. Eight minutes since the experiment started, the remaining gas had a mass of 339.5 grams. Let x be the number of minutes that have passed since the experiment started, and let y be the mass of the gas in grams at that moment. Use a linear equation to model the weight of the gas over time.
a. This line's slope-intercept equation is ___________
b. 31 minutes after the experiment started, there would be ____________ grams of gas left.
c. If a linear model continues to be accurate,______________ minutes since the experiment started, all gas in the container will be gone.
