Solve. y = -3x + 6 y = 10x – 7

pickupchik [31]

$y = -3x + 6\\
y = 10x - 7\\\\
-3x+6=10x-7\\
-13x=-13\\
x=1\\\\
y=10\cdot1-7\\
y=3\\\\
\boxed{x=1,y=3}

Which of the following is not equal to cos⁡(520°)?

Gnoma [55]

The cosine repeats itself every 360 degrees, and it mirrors at 0 and 180 degrees. It inverts around 90 and 270.
So without using a calculator, you can tell that:

cos(520)=cos(520-360)=cos(160)
cos(160) = cos(180-20) = cos(180+20) = cos(200)
cos(160) is NOT equal to cos(20), it would be -cos(20).
cos(160) = -cos(20) = -cos(-20)

So C is the only one unequal.

According to the Vivino website, the mean price for a bottle of red wine that scores 4.0 or higher on the Vivino Rating System i

lozanna [386]

Answer:

The null hypothesis is $H_o : \mu = 32.48$

The alternative hypothesis is $H_a : \mu < 32.48$

$t = -1.504$

There is no sufficient evidence to conclude that the mean price in Providence for a bottle of red wine that scores 4.0 or higher on the Vivino Rating System is less than the population mean of $32.48

Step-by-step explanation:

From the question we are told that

The mean price of is $\mu = \$ 32.48$

The sample size is n = 56

The sample mean is $\= x = \$30.15$

The standard deviation is $\sigma = \$12$

The null hypothesis is $H_o : \mu = 32.48$

The alternative hypothesis is $H_a : \mu < 32.48$

Generally the test statistic is mathematically represented as

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

=> $t = \frac{30.15 - 32.48 }{\frac{12 }{\sqrt{60} } }$

=> $t = -1.504$

Generally the p-value is mathematically represented as

$p-value = P (t < -1.504 )$

From the z-table

$P(t < -1.504) = 0.066291$

$p-value = 0.066291$

From the value we obtain we see that

$p -value > \alpha$

Then we fail to reject the null hypothesis

Hence there is no sufficient evidence to conclude that the mean price in Providence for a bottle of red wine that scores 4.0 or higher on the Vivino Rating System is less than the population mean of $32.48

How long will it take $5,000 to double in an account that pays 1.6% simple interest?

forsale [732]

Answer:

43.667 years

Step-by-step explanation:

Simple Interest Rate Formula: A = P(1 + r)ⁿ

Step 1: Define variables

A = 10,000

P = 5,000

r = 0.016

n = unknown

Step 2: Substitute variables

10,000 = 5,000(1 + 0.016)ⁿ

Step 3: Solve for n time

2 = (1.016)ⁿ

$\log_{1.016}2$

43.667 years
