Answer:

The answer SHOULD be: 6.7 (unless if it's cash than 6.67)

Step-by-step explanation:

10 divided by 7 +250 "by" so 10 divided by (7+250), than divided by 60

10 division (7+250) division 60

10 division 257 division 60

(10 divided by 257 = rounds to 0.04) divded by 60

0.04 divided by 60 = 6.6666 (6 repeating) rounding to 6.7

Answer:

  a.  see attached

  b.  $140

Step-by-step explanation:

The graph starts at y=65 when x=0 and increases by 25 for each increase of 1 in x. The attachment shows a graph of the equation.

Use x=3 in the equation.

  -25x +y = 65

  y = 65 +25x = 65 +25(3) = 140

Answer:

1.  She made 91 shots.

2. She missed 30% of her shots, or 39 shots.

Step-by-step explanation:

1. 70% of 130 (or .7 times 130) is 91. The 70% is converted into decimals by moving the decimal 2 places to the left.
2. Out of 100%, 30% is the added percentage to make 100%. 30% of 130 (or .3 times 130) is 39. This can also be found my subtracting 91 from 130.

Answer:

the period of this graph is [tex]\pi[/tex]

Step-by-step explanation:

The period is the length of the section that repeats.  So for this graph, we need to calculate the distance between 2 peaks or 2 troughs of the curve.

Let's look at the peaks (maximums).

One is at x = 0 and the next is at x = [tex]\pi[/tex]

[tex]\pi[/tex] - 0 = [tex]\pi[/tex]

Therefore, the period of this graph is [tex]\pi[/tex]

Step-by-step explanation:

Yes these side lengths can make a triangle

The triangle side length rule states that any 2 sides of a triangle are greater than the other side.

Let's use this rule to determine if these side lengths can make a triangle.

4+7=11 and 11 is greater than 10.

4+10=14 and 14 is greater than 7.

7+10=17 and 17 is greater than 4.

These side lengths can make a triangle.

G'(x) = 1 × g(x) × f(x) + g'(x) × x × f(x) + f'(x) × x × g(x)

G'(x) = g(x).f(x) + x.f'(x).g(x) + x.g'(x).f(x)

Thus ;

G'(3) = g(3).f(3) + 3f'(3).g(3) + 3g'(3).f(3)

G'(3) = 13×9 + 3×( - 11 )×13 + 3×( - 5 )×9

G'(3) = 117 + ( - 429 ) + ( - 135 )

G'(3) = 117 - 135 - 429

G'(3) = - 18 - 429

G'(3) = - 447

Step-by-step explanation:

We need to convert the fraction into a whole number.

We have to solve 11 + 19 first:

30/3 = 10 so we need to increase the numerator:

Answer:

90

Step-by-step explanation:

First we take 11 to other side to give:

[tex]\frac{w}{3} = 19+11[/tex]

[tex]\frac{w}{3} = 30[/tex]

Now we escalate the 3 up to give

w = 30×3

w=90

To double check we can substitute our value of w into the original equation:

[tex]\frac{90}{3}-11 = 19[/tex]    ✅

I don't know what kind of calculator you have at your disposal, so I'll just give one way of computing the sample mean and standard deviation.

• To get the mean, add up all the data points and divide the total by the number of data:

[tex]\bar x = \displaystyle \sum_i \frac{x_i}n = \frac{1243+1264+\cdots+1275}9 \approx 1273.89 \\ \implies \boxed{\bar x \approx 1274}[/tex]

• To get the s.d. s, first compute the variance s² by adding up the squared difference between each of the data points and the sample mean, and divide the total by 1 less than the number of data:

[tex]s^2 = \displaystyle \sum_i \frac{\left(x_i-\bar x\right)^2}{n-1} = \frac{(1243-1274)^2+(1264-1274)^2+\cdots+(1275-1274)^2}8 \approx 1211.61[/tex]

The s.d. is the square root of the variance:

[tex]s^2 \approx 1211.61 \implies s \approx 34.8082 \implies \boxed{s\approx 35}[/tex]

The 90% confidence interval for the sample mean has upper and lower limits, respectively, of

[tex]\bar x \pm \dfrac{\left|Z_{\alpha/2}\right| s}{\sqrt n}[/tex]

(positive root for upper limit, negative root for lower limit)

where [tex]Z_{\alpha/2}[/tex] is the critical value for a (1 - α)×100% confidence level. By critical value, I mean

[tex]\mathrm{Pr}\left[ Z \le Z_c \right] = c[/tex]

where Z is a random variable following the standard normal distribution.

In this case, we have a 90% confidence level, so α = 0.1, and the critical value is [tex]Z_{0.05} \approx -1.64[/tex]. Then the confidence interval has upper limit

[tex]\bar x + \dfrac{\left|Z_{0.05}\right|s}{\sqrt n} = 1274 + \dfrac{1.64 \times 35}{\sqrt9} \approx 1292.97 \approx \boxed{1293}[/tex]

and lower limit

[tex]\bar x - \dfrac{\left|Z_{0.05}\right|s}{\sqrt n} = 1274 - \dfrac{1.64 \times 35}{\sqrt9} \approx 1254.8 \approx \boxed{1255}[/tex]
