Answer:

$333.3\%$

Step-by-step explanation:

We want to express 3⅓ as a percentage.

Let us first of all rewrite 3⅓ as decimals to obtain:

$3 \frac{1}{3} = 3.3333...$

To express this as a percentage, we multiply by 100%

$3 \frac{1}{3} = 3.3333... \times 100\%$

This multiplies to give us:

$3 \frac{1}{3} = 333.3\%$

The x3 was supposed to be an exponent not 3x

mote1985 [20]

Answer:

The value of x is $2\sqrt[3]{2}$

Step-by-step explanation:

We are given $2+x^3=18$

We need to solve for x

First we subtract 2 both sides

$x^3=18-2=16$

Taking cube roots both sides to isolate x

$x=\sqrt[3]{16}$

Simplify the radical

$x=2\sqrt[3]{2}$

Thus, The value of x is $2\sqrt[3]{2}$

Suppose you are determining whether the depth of groves cut into aluminum by a milling machine is equal to 1.7 mm. You cut 14 gr

Gemiola [76]

Answer:

For this case we want to check if the true mean for the depth of groves cut into aluminium by a machine is equal to 1.7 (null hypothesis) and the alternative hypothesis would be the complement different from 1.7. And the best system of hypothesis are:

Null hypothesis: $\mu =1.7$

Alternative hypothesis $\mu \neq 1.7[/tx]And the best system of hypothesis are:3. This two-sided test:
H0: μ = 1.7 mm
H1: μ ≠ 1.7 mmStep-by-step explanation:For this case we want to check if the true mean for the depth of groves cut into aluminium by a machine is equal to 1.7 (null hypothesis) and the alternative hypothesis would be the complement different from 1.7. And the best system of hypothesis are:Null hypothesis: [tex]\mu =1.7$

Alternative hypothesis [tex]\mu \neq 1.7[/tx]

And the best system of hypothesis are:

3. This two-sided test:

H0: μ = 1.7 mm

H1: μ ≠ 1.7 mm

Solve 11sinθ-2=2 for a value of θ when 0≤θ≤π/2.? How do you solve the second problem?

Sergio [31]

5cos (2x)+7=cos (2x)+8, 4cos (2x)=1, cos (2x)=1/4, 2x=arccos(1/4), x=(1/2)arccos (1/4). I used x instead of theta, and arccos is cos inverse

Find the student’s error in solving the following inequality.

Mars2501 [29]

Answer:

The correct option is:

The student should have switched the direction of the inequality sign to get –5> x for a final answer

Step-by-step explanation:

The students has made a mistake in the 3rd step.

We know that when we multiply or divide any negative number on both sides of the inequality, the sign of inequality reverse its direction.

In step 3 the student divided 25 by -5 but did not switch direction of the inequality sign.

Therefore the correct option is: The student should have switched the direction of the inequality sign to get –5> x for a final answer

"At most 12" means "the highest we can go is 12". Think of it as the ceiling. So x can equal 12 or it can be smaller. This means $x \le 12$
