Answer:

6.6%

Hope this helps!

Step-by-step explanation:

Oof I am not a fan of chairs right now!

Let's see what info we can collect:

A Chair cost= $75

Total cost + tax = $80

Our Formula:

Tax= final cost- original cost

Let's Solve!!!

Tax rate= 80-75

Tax rate= $5

Tax Percentage = 5/75 * 100

= 6.6%

Answer:

A chair cost $75. The total cost of the chair was $80. What was the tax rate on the chair?

A Chair cost= $75

Total cost + tax = $85

Tax= final cost- original cost

Tax rate= 85-75

Tax rate= $10

tax percentage = 10/75x100

= 13.33%

Triángulo equilátero = todos los 3 lados son congruentes ("equilátero" = lados iguales)

Triángulo isósceles = solo 2 lados son congruentes

Triángulo escaleno = todos los lados son diferentes

El triángulo que se muestra aquí es isósceles porque 2 de los lados tienen la misma longitud de 7 cm.

Answer:

(d)

Step-by-step explanation:

Multiple your numbers out first. This always makes it less hectic to look at. Multiply both sides by x to move the x to the right side. Then divide both sides by ((0.4365)(87.9)). You should get 10.

Georgianna claims that in a small city renowned for its music school, the average child takes at least 5 years of piano lessons.

Allisa [31]

Answer:

The condition are

The Null hypothesis is $H_o : \mu = 5$

The Alternative hypothesis is $H_a : \mu < 5$

The check revealed that

There is sufficient evidence to support the claim that in a small city renowned for its music school, the average child takes at least 5 years of piano lessons

Step-by-step explanation:

From the question we are told that

The population mean is $\mu = 5 \ year$

The sample size is n = 20

The sample mean is $\= x = 4.6 \ years$

The standard deviation is $\sigma = 2.2 \ years$

The Null hypothesis is $H_o : \mu = 5$

The Alternative hypothesis is $H_a : \mu < 5$

So i will be making use of $\alpha = 0.05$ level of significance to test this claim

The critical value of $\alpha$ from the normal distribution table is $Z_\alpha = 1.645$

Generally the test statistics is mathematically evaluated as

$t = \frac{\= x - \mu}{ \frac{\sigma }{\sqrt{n} } }$

substituting values

$t = \frac{ 4.6 - 5}{ \frac{2.2}{\sqrt{20} } }$

$t = -0.8131$

Looking at the value of t and $Z_{\alpha }$ we see that $t < Z_{\alpha }$ so we fail to reject the null hypothesis

This implies that there is sufficient evidence to support the claim that in a small city renowned for its music school, the average child takes at least 5 years of piano lessons.
