Answer:

\sqrt{x}

Step-by-step explanation:

<u><em>The correct question is</em></u>

Rewrite in simplest radical form  1/x^−3/6

Show each step of your process please

we have

\frac{1}{x^{-\frac{3}{6}}}

Remember the negative exponent rule

\frac{1}{x^{-n}}=x^{n}

so

\frac{1}{x^{-\frac{3}{6}}}=x^{\frac{3}{6}}

Simplify

x^{\frac{3}{6}}=x^{\frac{1}{2}}

Remember that

x^{\frac{n}{m}}=\sqrt[m]{x^{n}}

so

x^{\frac{1}{2}}=\sqrt{x}

Some Field Experience in the use of an Accelerated Method in Estimating 28-Day Strength of Concrete" considered regressing y =28
Brums [2.3K]

Answer:

<h2>(a) 5,050 psi.</h2><h2>(b) 5,051.3 psi.</h2><h2>(c) 5,180 psi.</h2><h2>(d) 4,920 psi.</h2>

Step-by-step explanation:

The given function is

y=1800+1.3x

Where x represents the accelerated strength in psi, and y represents 28-day standard-cured strength in psi.

Part a is about finding the y-value for x=2500

y=1800+1.3(2500)=1800+3250=5,050

Therefore, the expected value of 28-day strength when accelerated strength is 2,500, is 5,050 psi.

Part b is about the y-value for x=2501

y=1800+1.3(2501)=1800+3251.3=5,051.3

Part c is about the y-value for x=2600

y=1800+1.3(2600)=1800+3380=5,180

Part d is about the y-value for x=2400

y=1800+1.3(2400)=1800+3120=4,920

425 students in the 9th, 10th, and 11th grades were asked if they ride the bus to school. The results are shown in the two-way f
Ipatiy [6.2K]

The true statements are:

  • 44/85 of the student surveyed do not ride the bus to school
  • About 32% of the students are in the 9th grade

The false statements are:

  • 64% of the students are 11th graders
  • 134/150 of the students surveyed are in 9th or 10th grade

<h3>How to interpret the two-way frequency table</h3>

<u>The students that do not ride bus to school</u>

From the table, 220 students do not ride bus to school.

So, the proportion of students that do not ride bus to school is:

p=\frac{220}{425}

Simplify

p=\frac{44}{85}

Hence, this statement is true

<u>The 9th graders </u>

From the table, 134 students are 9th graders

So, the proportion of students that are 9th graders is:

p=\frac{134}{425}

Divide

p=0.315

Approximate, and represent as percentage

p=32\%

Hence, this statement is true

<u>The 11th graders </u>

From the table, 141 students are 11th graders

So, the proportion of students that are 11th graders is:

p=\frac{141}{425}

Divide

p=0.331

Approximate, and represent as percentage

p=33\%

Hence, this statement is false

<u>The 9th or 10th graders </u>

From the table, 134 + 150 students are 9th or 10th graders

So, the proportion of students that are 11th graders is:

p=\frac{134 + 150}{425}

p=\frac{284}{425}

Hence, this statement is false
