Answer:

Option 1.

Step-by-step explanation:

If the inequality contains the signs < or > then the number line should have an open dot (the dot is not colored in). If the inequality contains the signs ≥ or ≤ then the number line should have a closed dot (the dot is colored in).

Since the sign is < you should pick the number line with the open dot that has an arrow facing the left side instead of the right, which is option 1.

I hope this helps you, have a nice day.

Alex says that the function f(x) = (3x)2 represents a vertical stretch of the quadratic parent function by a factor of 3. Marta

gavmur [86]

Our parent function is f(x)=x^2. A vertical stretch by a factor of k means that every point (x,f(x)), has been transformed into (x,kf(x)). Alex is clearly incorrect as our parent function has been transformed to (x,9f(x)), not (x,3f(x)). A horizontal stretch(or compression) by a factor of k means our function has been transformed to (x/k,f(x)). Here, Marta is saying our function should look like (3x,f(x)). This can also be achieved by plugging 3x into the parent function, which would give us f(3x)=(3x)^2, so it seems that Marta is the correct one.

Answer:

C) The test provides the convincing evidence that the proportion is greater than 90%, but the actual proportion is equal to 90%.

Step-by-step explanation:

Options are missing from the question. The complete question with its options is shown in the image below.

We need to describe about the Type 1 error. In Statistics there are two main errors: Type 1 error and Type 2 error.

Type 1 Error occurs when we reject the null hypothesis when infact its true.
Type 2 Error occurs when we fail to reject the null hypothesis when infact its false.

In the given case the Null Hypothesis is:

The proportion of all washers produced with the specified diameter is equal to 90 percent.

The Type 1 error will occur when the test results will reject the Null hypothesis and accept that the specified diameter is greater than 90% , when infact the Null hypothesis is true and actual proportion is equal to 90%.

Therefore, the correct option will be:

C) The test provides the convincing evidence that the proportion is greater than 90%, but the actual proportion is equal to 90%.
