Help i dunno the answer to it :

Novay_Z [31]

Answer:

5 miles per hour

Step-by-step explanation:

Let the speed of Kelly is $v_1$ miles per hour and speed of Raul is v₂ miles per hour.

Since, speed = $\frac{\text{Distance}}{\text{Time}}$

Kelly took 135 minutes to cover 90 miles from New York to Philadelphia.

∵ 1 minute = $\frac{1}{60}$ hours

∴ 135 minutes = $\frac{135}{60}$ = $\frac{9}{4}$ hours

v₁ = $\frac{90}{\frac{9}{4}}$

= $90\times \frac{4}{9}$

= 40 miles per hour

Raul took 153 minutes to cover the same distance as Kelly,

∵ 1 minute = $\frac{1}{60}$ hours

∴ 153 minutes = $\frac{153}{60}$ = $\frac{51}{20}$ hours

v₂ = $\frac{90}{\frac{51}{20}}$

$=90\times \frac{20}{51}$

= 35.29

≈ 35.3 miles per hours

v₁ - v₂ = 40 - 35.3

= 4.7

≈ 5.0 miles per hours

Therefore, Kelly is 5 miles per hours faster than Raul.

Please answer this question based on the following data. SSTR = 6,750 H0: μ1= μ2=μ3=μ4 SSE = 8,000 Ha: at least one mean is diff

Nookie1986 [14]

Answer:

$P_v =P(F_{3,16}>4.5)=0.0180$

So on this case the best option for the answer would be:

between .01 and .025

Step-by-step explanation:

Analysis of variance (ANOVA) "is used to analyze the differences among group means in a sample".

The sum of squares "is the sum of the square of variation, where variation is defined as the spread between each individual value and the grand mean"

If we assume that we have $4$ groups and on each group from $j=1,\dots,5$ we have $5$ individuals on each group we can define the following formulas of variation:

$SS_{total}=\sum_{j=1}^p \sum_{i=1}^{n_j} (x_{ij}-\bar x)^2$

$SS_{between=Treatment}=SS_{model}=\sum_{j=1}^p n_j (\bar x_{j}-\bar x)^2 =6750$

$SS_{within}=SS_{error}=\sum_{j=1}^p \sum_{i=1}^{n_j} (x_{ij}-\bar x_j)^2 =8000$

And we have this property

$SST=SS_{between}+SS_{within}=6750+8000=14750$

The degrees of freedom for the numerator on this case is given by $df_{num}=k-1=4-1=3$ where k =4 represent the number of groups.

The degrees of freedom for the denominator on this case is given by $df_{den}=df_{between}=N-K=20-4=16$ .

And the total degrees of freedom would be $df=N-1=20 -1 =19$

We can find the $MSR=\frac{6750}{3}=2250$

And $MSE=\frac{8000}{16}=500$

And the we can find the F statistic $F=\frac{MSR}{MSE}=\frac{2250}{500}=4.5$

And with that we can find the p value. On this case the correct answer would be 3 for the numerator and 16 for the denominator.

$P_v =P(F_{3,16}>4.5)=0.0180$

So on this case the best option for the answer would be:

between .01 and .025

Write a real world problem that involves a percent then model the percent used in the problem

s344n2d4d5 [400]

You go to a restaurant and your bill is $35.00. Your service was excellent so you leave a 20% tip. What was the total amount paid for the bill including the tip?

10%=$1 for every $10
15%=$1.50 for every $10
20%=2% for every $10

10% of the bill would be $3.50(move the decimal to the tens place)
15% of the bill would be $5.25( halve the 10% and add it to the original 10% tip; $3.50+$1.75)
20% of the bill would be $7.00(double the 10% tip)

(8w^7 x^-5 y^3 z^-9)^2/3 Please find an equivalent answer to the problem.

-BARSIC- [3]

Answer:

your answer will be option A

Step-by-step explanation:

(8w^7x^-5y^3z^-9)-2/3

= (8)-2/3×(w^7)^-2/3×(x^-5)^-2/3×(y^3)^-2/3×(z^-9)-2/3

=(2^3)^-2/3×w^-14/3×x^10/3

xy^-2xz^6

=2^-2 w^-14/3 x^10/3 y^-2 xz^6

=1/4×1/w^14/3× x^10/3 xz^6/y^2

=x^10/3z^6/4w14/3y^2

hope it helps..

have a great day!!
